Re: [RE-wrenches] Enphase Gateway causing lamp to flicker

Hi Adam, We have a clause in all of our contracts that reads “prices not include any un-anticipatable events”While I can understand the need to placate clients, the days of solar martyrdom needs to end!

It seems like when the Enphase Gateway is powered up it causes the lights to freak out. Once we flip the breaker to the Gateway off the lamp operates as normalZ Interestingly, with another load (homeowner was using a dehumidifier) plugged into the circuit it seems to stabilize the lights. We isolated the problem to the Gateway specifically (ie having PV breakers on/off doesn’t make a difference). It’s a supply side connection. The house is small but we tried the lamp in multiple parts of the house and it happens everywhere.  Enphase doesn’t have any ideas. Anyone have this happen to them? I think we might just need to buy them some new lamps, but I’m also interested to understand what is happening. These are just some cheap lamps, but wondering if other household loads that are more sensitive might be affected as well?  Adam

You might want to replace the screws with something shorter

  1/2" plywood.

Hi All,


I've run into a roof-mounted job where the roof is
  built-up with the following:


Comp shingle
Plywood
Foam board
T&G (roof deck, but also interior ceiling)


The beams that hold the t&g up are wide-spaced and
  not convenient for fastening the full extent of the
  array.  



This being the case, I was considering other fastening
  options and am writing to pick the collective brain of the
  Wrenches to see how others have addressed similar
  situations.


One thought I had was to use the PLP Easy Mounting Foot
  and I'd be glad for any opinions on that or another
  solution.

What has changed?  I have spent hours on the phone, often times being

Re: [RE-wrenches] Protecting New Roofing during Summe

[Solar Energy Solutions]

Great Question James.  We too have tried sprinklers and soaker hoses, rugs and 
mats with only mixed success.  
After years of blistered feet and even burned butts we try to make a point of 
being off a hot roof by noon.  I also try to get our guys to think of walking 
on a roof as one might walking on rice paper without tearing it.

Re: [RE-wrenches] MLSD module level shutdown

[Solar Energy Solutions]

Dear All,
I apologize for letting this conversation get a little stale before being able 
to comment further.
Before I reply, I would like to say I don't believe MLSD has anything to do 
with firefighter safety.  If being on dangerous roofs was really a concern, 
steep roofs, slate roofs, metal roof, wet metal or shake roofs and snow on 
roofs would get the same kind of scrutiny as solar on roofs.  I can only guess 
and think that some HUGE solar hating utility company devised this whole 
firefighter safety thing.  It is also my understanding none of the string 
inverter folk turned up to the code development meetings where MLSD was 
determined and you can guess who was.    But much of this is only rumor and the 
dark thoughts of a solar bozo.

I HATE the hassle and maintenance issues of MLSD.  I loved string inverters and 
hated to see them go.  So far as I can tell the US is the only place on planet 
Earth to make String inverters all but illegal.  This said... a picture is 
worth a thousand words.  All of the attached photos of systems had the wire 
management done very well.  If you look at the metal roof photo you can see a 
small hole in it from the arc.  I have many more photos of different squirrel 
damaged systems.  Ground Fault protection has saved the inverters, but not the 
roofs.

I don't really like the idea of squirrel guards.  It seems like I may be 
creating another problem down the road that I can't really imagine.  Debris 
build up could be an issue.  Rainwater could back up from a damn and get under 
shingles and into the cavity of the house.  For me the easiest thing that could 
be done is for some kind of a bittering agent to be part of the wires so that 
one little lick would send a critter looking for a better food source.

I totally agree; where else does the NEC allow loose single conductor cables to 
run unprotected? outdoors?  All because the module manus and industry in 
general has made no effort, zero, to accommodate any type of electrical

gone this wacky direction, starting about 15 years ago, we probably wouldn't be 
having this conversation, because there would be much less reason for MLSD. 
 
 
I could see whips of TEK 90 that plugged into polarized 2 pole quick connects 
mounted integrally to a J box on the back of each module.

 There’s a buried-in-plain-sight issue here that has bugged me for years. 

In the bad old days we had to hard wire into J-boxes on the backs of modules. A 
pain, but it meant that, if necessary, we could install conduit from the module 
to the combiner box. Now we have convenient pigtails.

 However, we are stuck with #10 PV wire hanging under the module from the box 
to the nearest attachment point. There are all sorts of trays and wire 
management systems, but there’s always that one loop of wire hanging in the 
open. 

I know that the module industry has near zero margins as a commodity market. 
Perhaps one manufacturer could differentiate themselves by making a module with 
either 1) armored pigtails, or 2) provision for some kind of conduit starting 
at the J box.

I’m thinking of all the various back covers installers have to improvise on 
ground mounts. I’m thinking of squirrels and ice dams. 

Why can’t there be a module with the equivalent of Teck 90 cable on it?

Maybe I’m just being naive.

Re: [RE-wrenches] MLSD module level shutdown

[Solar Energy Solutions]

Dear All,
I have been an outspoken critic of module level shutdown for all the reasons 
folks do.  However, I have come around.  We have witnessed too many systems 
where rooftop wiring has been chewed up by critters... mostly squirrels.  We 
have seen everything from residential fires to holes in metal roofs caused by a 
DC arc.   I never thought I would see the day when I would not only be thinking 
MLSD is a good idea but advocating for it.

 So far the module level shutdown requirements have been a real blow to our 
industry. The reliability and cost from a maintenance and installation 
standpoint has been very hit or miss so far. It feels like this requirement was 
rolled out far too quickly without enough forethought to its impact on the 
industry. We are constantly going out and fixing problems with mlsd installed 
by other contractors. Thankfully the problems have nothing to do with the 
quality of the installations. The problems are almost all due to premature 
failure of the products or some inherent defect in them. This is a serious 
issue costing the industry time and resources and making our installers less 
safe. It just doesn’t really accomplish the intended goal of the requirement. 
I’m curious how other wrenches are dealing with this issue. I recently became 
aware of fixMLSD.com which appears to be focused on bringing a more sensible 
approach to this requirement. 

Your thoughts are appreciated,

Speaking of rails...  What are thoughts about how much rail to leave sticking 
out from an array.  It seems the industry has moved towards trying to make the 
rails invisible by designing them to be cut at the edges of an array.
I don't like this practice and try to leave at least 4 - 6 inches sticking out. 
 The reason for this is to make it easier for those who follow when the roof 
needs re-roofing.     

We also don't install skirts as we believe this hurts the efficiency of the 
system... but are open to hearing the contrary.

[RE-wrenches] ITC for the Second Time

[Solar Energy Solutions]

Dear Wise Wrenches,
We have a client who installed a GT system with us in 2015.  They now want to 
install another system on the same house.  Will they still qualify for the 30% 
ITC?  Or is that a one time only thing?
Thanks a Ton!

Re: [RE-wrenches] SunBandit Solar PV Hot Water

[Solar Energy Solutions]

Hi Kirpal and All,
Our 30 experience with solar hot water has not been good.  These experiences 
aside, I wonder why go through the expense of installing a SunBandit?  Wouldn't 
a client, given enough roof space, be better off with a net metered system and 
a conventional electric hot water heater?
Thank you for your thoughts,

[RE-wrenches] Defective UFOs
Solar Energy Solutions Tue, 10 Oct 2017 18:21:07 -0700

Dear Wrenches,We were at a project yesterday and were quite perplexed as to why
we were breaking so many Iron Ridge UFOs.. 15 on a 10kW.  Had it not been for
us attending an IR workshop today it would still be a mystery and the problem
would continue to plague us for the next several installation.
Below is the IronRidge reply.
A couple batches of black ufo made it out in the market place due to a machine
calibration issue that has been identified and fixed. The customers are to send
an email tosupp...@ironridge.com If they come across any bad product and will
be taken care of with new product and a return address to send the bad ones
back to the factory. Smiles,

[RE-wrenches] Panels Damage in Delivery

[Solar Energy Solutions]

Dear All,
I am learning for the first time, and the hard way, the necessity of checking 
deliveries for damaged panels.  For the first time I am hearing that it is not 
uncommon for the bottom or last panel to be damaged in shipping.  Nobody ever 
explicitly tells you this until it is too late.  It is ridiculous to think 
folks are going to physically unload a pallet of panels just to make sure the 
bottom panel is not damaged.  And yet... We are now without recourse as the 
bottom panel was not discovered until a month after delivery and we are now in 
desperate need of a Solar World 325.  Unicorns, attractive naked people and 
Obamas to anyone who has one.
Probably best to contact me off list.

 Hello,I 
recently upgraded a 12 year old Sanyo HIT 167 watt (14 total) array to a 
Solaredge system while adding two strings of LG 315’s. Every time there is rain 
or heavy condensation the inverter shuts down with a ground fault error. I was 
able to isolate the error to the old Sanyo string. The Solaredge diagnostics 
estimated the fault was in the middle of the string. So we went up on the roof 
with a garden hose and trickled water on each panel individually, while 
meggaring the string at the roof combiner. Sure enough, the moisture 
infiltration was in the middle panel of the string, just as the Solaredge IRT 
test predicted. Good job Solaredge.These panels are circa 2004, so I’m 
wondering who the US contact is to ask about warranty issues. Has Panasonic 
taken over warranty claims on old Sanyo’s? I know this model isn’t made 
anymore, but maybe there is some remuneration offered. Thanks.

Re: [RE-wrenches] CA wrenches

[Solar Energy Solutions]

The Energy Trust of Oregon, the local administrator of the investor owned 
utilities incentive program, mandated an additional production meter be 
installed between the inverter in the circuit box for the first 11 years of the 
program. Finally, they changed that technical requirement so additional meter 
is no longer needed. A call to Portland General Electric or the Energy Trust of 
Oregon may prove helpful in developing an argument to dissuade the utility 
company of this requirement.

Subject: Re: [RE-wrenches] Protecting Asphalt Shingled Roofs  Hi James, Great 
topic! Minimizing roof wear and tear during installation is a big deal. We have 
Yellow Spaghetti mat 
(http://www.bestmaterials.com/PDF_Files/yellow-spaghetti-datasheet.pdf) and 
carpet scraps. Each has pros and cons. Spaghetti mat is durable and we use it 
over and over. It does get slippery when wet and doesn’t have good enough grip 
over ~ 26-30 degree pitched roofs. Carpet actually performs better when wet but 
it gets heavy and messy. We can also use carpet on steeper roofs where we 
actually tie it off to our anchors by making a hole in the top of the carpet 
piece and tying a rope to it.  It takes a lot of perseverance to get crews to 
consistently protect the roof to the level that is required to minimize damage. 
It has to be part of every installation plan just like fall protection. On hot 
days we try to get on the roof as early as possible and off the roof by the 
time the roof gets warm and soft. One of my colleagues mentioned that they 
would spray a roof down with a garden hose to cool it off on hot days, I  
haven’t personally tried that. AugustLuminalt From: RE-wrenches

Has any one used the Milbank tap connectors?
Or maybe get them approved by the utility?

It would require meter removal, but seems to be a good alternative to a

Re: [RE-wrenches] Access pathways

[Solar Energy Solutions]

The Death Knell of the Solar Electric Industry for residential roofs is the 
loss of available space. The mistake we see made over and over and over again 
is local jurisdictions  copying and pasting code hostile to the solar industry 
birthed as "suggested practices" for California and then making it law without 
any thought as to what devastating effect such actions have on the solar 
industry.  This is exactly what happened on Oregon.
But, one person going up against the entire 12 person, governor appointed board 
to develop code for the state, said, "NO WAY".  The fight was brutal and went 
all the way to the governor's desk.  Finally, the 25% rule was established... 
It should have been the 40% rule.

1.1. Where the PV array does not exceed 25% as measured in plan view of total 
roof area of the structure, a minimum 12 inch (305mm) unobstructed pathway, 
shall be maintained along each side of any horizontal ridge.
1.2. Where the solar array area exceeds 25% as measured in plan view of total 
roof area of the structure, a minimum of one 36 inch (914 mm) unobstructed 
pathway from ridge to eave, over a structurally supported area, must be 
provided in addition to a minimum 12 inch (305 mm) unobstructed pathway along 
each side of any horizontal ridge

Unless, we are going to require fire person friendly roofs everywhere that 
would also outlaw steep roofs, slate roofs, slick roofs, wood roofs and snow on 
roofs there is no reason to single out the solar industry with such toxic 
requirements.  Home Power and Solar Pro publish photo after photo after photo 
of PV installations that would fail the requirements so rapidly spreading 
across the nation like wild fire.

Dear Solar Colleagues,

I know the building code language regarding PV installations providing 3' 
access pathways was proposed and adopted in several states a few years ago. 

"3113.1.2.1 Residential buildings with hip roof layouts. Panels or modules 
installed on residential buildings with hip roof layouts shall be located in a 
manner that provides a 3-foot-wide (914 mm) clear access pathway from the eave 
to the ridge on each roof slope where panels/modules are located. The access 
pathway shall be located at a location on the building capable of supporting 
the live load of firefighters accessing the roof." (this is just a partial 
quote from here https://www.revisor.mn.gov/rules/?id=1305.3113)

This is a newly adopted code addition in MN, and there was absolutely no 
discussion with the solar industry. In MN we install solar on the south-facing 
roof as optimal, with perhaps the SE, SW, or even the east- or west-facing roof 
as possible options, but we almost without exception NEVER would mount solar 
panels on any roof with an azimuth 270 - 90 degrees (i.e. north of west or 
north of east). The requirement to leave a 3' walkway on all surfaces will in 
many cases diminish the amount of available roof surface for a residential 
solar PV installation to about 40% of previous designs. 

I see how this safety requirement may be necessary in a state where mounting 
solar panels on all roof surfaces is an option, but in MN since we can really 
only mount on the south-facing roof I don't understand how safety for fire 
fighters is a primary concern with this code addition. My understanding is that 
if there is another roof surface available, fire fighters would not choose to 
vent a roof with solar panels even if a 3' walkway is available -- so for what 
purpose are we avoiding that roof space for a solar installation?

Our local folks at the state level either don't understand these details or 
feel that there must be an overriding reason that this building code language 
has been adopted in other states. Can any of you give me input,

emblematic of the cheapening of the solar industry.  If a contractor cannot be 
bothered to get on a roof to provide an accurate assessment of the site, I 
wonder if they will be honest if it turns out there are shading or other issues 
not anticipated?  The entry level installer will never notice shading problems. 
 If there are undocumented shading issues, the consumer may never know they are 
being cheated out of some of the return on their investment. This is true also 
about the condition of the roof and electrical infrastructure.  We have seen 
the contracts offered by some of our competition.  They get the job by 
low-balling estimates and then make up the difference by contract “adders.” I 
believe that at some point a competent professional needs to get out of the 
office and in the field to evaluate each and every job before the contract is 
offered or the customer suffers.  I caution consumers:  if no one looked 
carefully at your roof and your electrical then you are not dealing with a 
reputable contractor. William Miller PS:  The Pathfinder is still a reliable, 
accurate alternative.  If you apply the values on the chart to a model adjusted 
for pitch, azimuth and local insolation you can get very accurate values for 
shading.  Those who can create a spreadsheet tool will find the results can be 
tabulated in short order. Wm

 So far, so good. No issues like that. However, on one job we had a problem 
with the bolt heads not "catching" in the rail channel and modules popping up. 
I chalked that up to an installation error by an installer that was easily 
resolved. Despite the convenience, I'm not a huge fan of t-bolts for top 
clamps. Square head bolts that you slide into the channel seem much more secure 
and less prone to error. However, the bonding feature makes the T-bolts worth 
the tradeoff.

 I'm curious if these vertical integrators will still make their acquired 
brands available to small dealers through distribution. When SolarCity snatched 
up Zep, I had concerns about being able to service or add onto existing Zep 
systems we installed. That's definitely a concern going forward, and reason to 
perhaps stick with the most compatible racking solutions available. We used 
IronRidge for a while, which is largely compatible with Unirac, but now we're 
back on the Unirac bandwagon.  Interesting times... Jason Szumlanski​Fafco

[Solar Energy Solutions]

Here is our ad. We are looking to hire a highly motivated individualinterested 
and excited about a career in solar energy.  During your apprenticeship you 
will learn howto design, service and install solar hot water heating systems, 
solar poolheating systems, and photovoltaic systems. 
To consider this as a career, a person must be extremely physically fit andable 
to work under the most strenuous of environmental conditions. Solarinstallation 
work is both physically and mentally difficult work and not forthe faint of 
heart.  Able to run one mileand perform several hours of Bikram in a row would 
be good watermarks.  The work consists of conditions including andnot limited 
to high temperatures in summer and cold and wet in the winter,ladders extended 
40 feet, very steep roofs with cliff like fall-offs, hot, hotattics, swimming 
through insulation in hot, hot attic and using a variety ofpower tools for work 
while swimming through insulation in hot, hot attics. 
A professional appearance is required and applicants should be 
personable,willing to take direction and able to maintain a positive and 
pleasant attitude.Pay is negotiable, but usually starts out at around 
$11.00/hour. Rapidincreases in wages are the goal. The top wage in the industry 
is about$22.00/hour. 
Along with a letter telling us why you feel you are suited, and skilled forthis 
particular job opening, send a resume and referrals.  Andrew

We also like the SunEarth panels.  Please make sure you put the Rheem tanks 
under an 80psi pressure test for 3 days and that it holds like a ROCK.  We 
prefer these tanks but have also found their heat exchangers to leak from time

 Bill, 
I'm based in Southern Colorado, so unfortunately don't have personal experience 
with NE CA distributors, but having said that,  I would recommend giving 
SunEarth a call. They make top-notch harp-style collectors in So Cal, and they 
private label a host of other Solar Thermal components, including Steca 
controllers. The folks I have talked to from their sales team are friendly and 
helpful and I'm sure they can tell you who in your area distributes their 
stuff. They might even sell to you directly. 
I prefer Resol controllers for our thermal projects and have found that Alpha 
Thermal Systems in Massachusetts is the place to get those controls. They also 
distribute PAW pumpstations and will ship for a reasonable price.

Re: [RE-wrenches] Setbacks for fire responder protection

[Solar Energy Solutions]

William,
 
Please feel free to add this link to your site.  The Oregon Code is precedent 
setting and should be copied and improved upon regarding rooftop access.  When 
I say improved, I mean that 60% or more of an entire roof be available to 
firefighter access leaving 40% for solar.  This should be the line in the sand 
for anyone representing the solar industry.  Fighting tooth and nail against a 
committee of 12 and without any industry support one Bozo got 25%.  See pg 26 
for the Koyaanisqatsi clauses.

Re: [RE-wrenches] Flashing vs Sealant... again (is sealant code defensible?)

[Solar Energy Solutions]

We are the McDonalds of roof penetrations. During the last 30 years we have 
literally made pincushions of the roof we have worked on. After millions of 
unflashed penetrations we have only had one leak.  Observing hundreds of Carter 
era systems we have never seen a mounting foot leak. Like Sasquatch sighting we 
have heard the stories. But from where we stand, we have seen exactly the same 
amount of both.  Geography may be a key factor.  

We have used Vulcum and Dimonic we equal success. 

We are now forced to use flashing. Oregon specialty code forces every 24" when 
within 3' of a peak or edge. Where rafters are 16"oc we are forced to install 
every 16".  Outside of 3' every 48". 

The solar industry sleeps.

Re: [RE-wrenches] Purchasing SunPower modules

[Solar Energy Solutions]

Hi Larry,
It is my very strong understanding that SunPower only distributes panels to 
their authorized distribution channels. The authorize distribution channel is 
bound by SunPower agreement not to resell those panels.  That said, I have 
personally experienced SunPower panels floating around from those other then 
authorized distributors  I wonder if the originator of these panels is still a 
SunPower dealer?  

Have a nice weekend

Re: [RE-wrenches] California State Fire Marshal's "Solar Photovoltaic Installation Guidelines

[Solar Energy Solutions]

Dear
Esteemed Colleagues,
The purpose of this email is to start sharing solutions to the roof top access 
issue.  
I am not an
expert in fire fighting.  However, one of
our best clientele demographic is firefighters.  I have learned the following 
from them.   1) Firefighters avoid jumping on roofs.  I witnessed this 
avoidance first hand along
with their venting technique during a home fire of my own.  It was a single 
story house with flames
pouring out of the back bedroom window.  They stormed the house and 
simultaneously set up a HUGE fan in a door to
blow out the smoke and vent the house (the house was saved).  It is my 
understanding this is how Europe and
other parts of the world have been fighting fires for decades.  2) On the rare 
occasion where they 
jump on a roof, a 3 foot pathway for a person carrying an 80lb pack offers no
appeal and alternate access and egress are employed. 
When I look
at houses in Germany and Japan, when I look at cover after cover after cover of
Home Power, and all of the articles and pictures within,  I don’t see any of 
these anti solar pathways
being employed.     
 
I know what
it is like to be in that room out manned and out gunned.  I know what it is 
like to part of a truly
insane process.  However, something as
over the top hostile to solar as this roof top access thing is a line in the
sand that needs to be refought and reestablished.  There is no excuse for the 
solar industry to
cave on this rooftop access issue.  If
folks in the room won’t listen to reason, it is time to usurp the process and
appeal to more reasonable minds. 
Unless we
are going to outlaw steep roofs, metal roofs, slate roofs, mossy shake roofs
and snow on roofs, singling out solar is irrational, hostile and extremely
detrimental to solar’s rapid, mass integration.
I can't hardly think of a more important matter to the solar industry than 
this.  I am here ready, willing and able to serve.
Thank you for your time and attention on this important matter.Andrew

Re: [RE-wrenches] On demand WH

[Solar Energy Solutions]

All,
 
We are finding, with rare exception, that despite claims by On Demand 
manufactures of  their units being, "solar compatible" most do not reach the 
common sense definition of being so.  I would suggest anyone installing a solar 
preheat tank before an on demand talk to no less than two people from the 
manufacture to confirm the nature of the solar compatibility and get a plumbing 
diagram from them as well.  We like the Takagi as it seems to be truly solar 
compatible.  Many of our clients have light switches installed to facilitate 
easily turning the unit on or off so in the summer they can get rid of needless 
short cycling or any phantom load.  But, honestly, for conventional homes we 
have moved away from advocating for on demands thinking standby heat loss for 
an occupied homes is so little that the expense of the 'maybe energy saving 
device', by and large does not warrant its use in these situations.

Hi Bill,

I'm still running an Aquastar 125BS (original French model, before Bosch bought 
them) that I installed in 1990. I've had to rebuild the water valve once (after 
a freeze up; it's in an unheated outside closet on the north side of my house), 
the high-temp sensor once, and I needed to replace the thermocouple a few times 
when I was just using a small propane tank to run it. I installed a 250 gallon 
propane tank in the late nineties and haven't had to replace the thermocouple 
since. 

The Aquastar still works great, even when my incoming water temp is near 
freezing. I just have to use less cold-water mix during the winter.

Are you finding the new Bosch models to be this reliable?

Hi Bill, et al,

There are two major categories of tankless water heaters-natural draft (which 
work very similar in control aspect to a conventional tank i.e.. 
no electric required, some form of pilot light) and power vented (all power 
vented machines have need for at least a fan, most a computer with some form of 
display included - if your own body is incapable of telling you if the water is 
sufficiently hot).

Of the Big Five (major players in the tankless market) all manufacture one or 
more models of power vented tankless. Today, only Bosch markets a natural draft 
tankless. Bosch offers more than one model of natural draft tankless, standing 
pilot and intermittent pilot. If you like simple, trouble free, and low life 
cycle cost, you have but one choice.


http://www.bosch-climate.us/files/201304181918370.520PN_English_06.2011.pdf

What must be properly addressed with _any_ tankless is intake and exhaust 
venting, gas line sizing, and water quality. Since this isn't a tank, the pilot 
flame does almost nothing in terms of freeze prevention.

Some manufacturers state flow rate for their heaters without also providing 
temp rise. Flow rate without temp rise is meaningless. The above is a 117,000 
BTU/h machine. Sometimes winter ground water temperatures are significantly 
colder than summertime temps. If you want hot water in the winter, too, make 
sure you use the appropriate temp rise. Hardness is the biggest issue with 
water quality, if you scale the heat exchanger you won't get the performance 
advertised. If you have hard water, a water softener or descaling _as required_ 
is necessary.

I am a big fan of tankless and have been since '89 when I was first introduced 
to them as a user. Today, I install and troubleshoot all five major 
manufacturers. Co-located with the load, tankless provides you not only endless 
hot water but also instant hot water.

Good luck,

Re: [RE-wrenches] SHW - parallel tanks

[Solar Energy Solutions]

 
For years we installed, "Double Whammy" bypass valves enabling folk to go 
'solar only', 'solar preheat', or 'primary only', hoping folk would bypass and 
turn off their primaries during the summer season.  We did this ourselves for 
years.  However, going back on those 'DW' systems years later and asking the 
owners if any of them ever, ever used them even after having paid for them... 
and the answer was always, 'no'.    Like Jeremy says, just turn off the primary 
and the boiling hot water from the solar tank should keep the primary tank nice 
and hot.  
 
In the mean time we have moved to a 120 gallon Rheem single tank DB system with 
a steca controller and a digital Intermatic timer that only turns the heater on 
for an hour twice a day in the winter and is kept off all summer long.

Hi,
 
Every summer I get a few calls from annoyed hot water customers who can’t stand 
hearing their boiler fire merely to keep the indirect tank up to setpoint 
temperature, when of course the solar preheat tank is at 160 degrees or better 
at mid-day. So what’s the best way to transfer heat, in essence temporarily 
putting the tanks in parallel, from the solar tank to indirect? I can think of 
a few possibilities using a circulator and temperature controller, and a 
additional connection between the tanks, such as the tank drains plumbed 
together as a return line, but where is the best place to locate the circulator 
in a standard preheat arrangement (i.e. hot output of solar preheat plumbed to 
cold input of indirect tank)?

Re: [RE-wrenches] SHW Schuco issue

[Solar Energy Solutions]

Dear SWH Wrenches,
 
I was about to start out raging against the machine, but, what's the use.  This 
Tyfocor LS I am thinking is going to be a big issue.  The &^$(*^ Schuco glycol 
is of such a special nature not even the CIA can replicate it... and it is the 
only glycol sanctioned by Schuco for use in their system.  The good news is 
that after e n d l e s s hours chasing this thing down and for the most part 
coming up empty handed, I found a guy... who has some pallets.  I was able to 
successfully order some Tyfocor LS from him last fall.  Below is an email he 
sent us along with his contact information.  The 'guy' is a small, 'wing it 
theater' kind of a guy.   Pleasant enough to work with as long as you don't 
expect anything too polished.  
 Hi Andrew,

Thanks for your interest for the Schuco Solar Heat Transfer Fluid.
As long as Schuco International KG supplies solar components we will find a way 
to make those components available.

For your existing service situation, the excess quantity of Solar transfer 
fluid that was purchased for CT projects could be a solution.
Currently 144 PU or 180 PU of original Schuco 232105 is available for delivery.

Price: $26.5/container (10 liters or 2.65 gallons)

If you are interested in the whole pallet or partial quantity, please respond 
to this e-mail.

Best Regards

Were you successful in tracking down one of these pumps?  We have a number of 
Schuco units in the field all running fine at present, but it would be good to 
have a part source when the time comes.  Any joy locating a US distributor for

Re: [RE-wrenches] SHW Schuco and Labor warranty issues

[Solar Energy Solutions]

Our biggest issue with Schuco moving on is finding their 'typhocor' glycol... 
which is of such a special nature that not even the CIA know what the heck it 
is, or what makes it so special or where in this great country of ours we can 
get it.
 
So far as Labor warranties it has been my crusade to get manufactures to pay a 
decent labor rate for things that fail all to quickly or worse still, right out 
of the box.  In the Thermal industry I have been hammering panel manufactures 
for a 5 yr $500.00 labor warranty.  The standard is... wait for it... $100.00.

Re: [RE-wrenches] Stainless Steel Cable Ties

[Solar Energy Solutions]

We have used black cable ties since 1987 to strap sensor wire to PVC pipe for 
our solar pool heating systems.  I was just at a system we installed in 1989 
mounted on an East facing roof yesterday.  The exposed 20g sensor wire still 
had intact and plyable sheilding and the black cable ties still firmly attached 
and not brittle.  We have other similiar scenes with systems mounted on South 
facing roof were the black cable ties are still in tact under full solar 
exposure... for Portland Oregon.  Yanking on some of these cable ties sometimes 
break the ancient tie.  But, more often than not, as yesterday, we have to 
break out our wire cutters to accomplish this task.

Thus, I gotta think that black cable ties under a PV array which are not 
exposed to any of the heat or sun we usually subject them to... are going to 
last an even longer time.

Make sure you use black cable ties, the white ones fail in UV from sunlight.

Corey,
If rain water isn't doing good enough, which it usually does depending on angle 
and other factors…..

-pick up a window washing squeegee (like at a gas station) that you can add a 
longer, maybe telescopic handle.  That works great.
-Just use water, it works fine.  There is no need for additional chemicals or 
cleaners.  If bird crap or dirt is particularly stubborn just wet it, scrub it, 
wet it again and let it soak a few minutes, then it should wipe right off.  
Keep in mind most module mfgrs recommend nothing more than a mild detergent 
added to water (read the specific module instructions).  
-Be wary of temp differences between water and module glass.  Cold water on hot 
glass can cause the glass to crack.  Best to wash in the morning before the 
glass heats up.

I've seen a few module washing products (automatic sprayers) advertised, but 
have no first hand experience with any.

Good luck,
benn

[RE-wrenches] 14 inch aluminum standoffs?

[Solar Energy Solutions]

Dear All,

While not participating much in the dialog  I greatly appreciate your time and 
knowledge on matters of the Sun.

My question is two fold.  Are folks using galvanized or hot dipped galvanized 
in any way, shape or form out there for their mounting systems?  I feel like I 
need to know this as we only use aluminum because our climate is so wet.  Yet 
we are in a situation where using galvanized might be the best and only 
options, although we am not seeing anything with galvanized that is readily out 
there either.

Fold Two:  Does anyone know of a source for 'standoffs' that are greater than 
7"s but less than say 20"?

Sincerely,

Sounds like you already have the
equipment.  But perhaps next time consider DPW’s Easy Feet.  They are
made to tech-screw right into the decking without having to hit the truss. 
Come pre-made with EPDM.  Just snap a line, set and screw.  Obviously you will
need to do some math to make sure your decking material is substantial as well
as anchored well to the blue board.  I have not used them yet, but will be 
putting
up 20kW next month and will report back.  That being said, anybody else have
experience to report with them?

Subject: [RE-wrenches] Best practices for comp shingle flashing?


Hey guys,
 
What's the consensus on the best practice for flashing roof penetrations on 
existing (not new) comp shingle roofs? 
 
I don't like Oatey because the boot degrades quickly and even shaded under the 
modules I don't like the idea of using an inferior product. The flashing on 
Master flash is quite extensive; I don't like disturbing the established 
roofing material as much as is required with Master Flash...nor do I like the 
idea of having to trim so much of the flashing. Quick-mount is easy but I 
really don't like the lack in height versatility plus the fact that there is no 
decent way of retracting the lag bolt. I know there must be a better way.
 
I recall in the old days (old for me anyway) we used to just mount L-feet to 
the shingles and on my own house I mounted stand-offs directly to the shingles 
because I'm confident in that method. But, I need something with more insurance 
when working on other people's homes.
 
William, what are you using these days?

any kind of a warranty on it.  I have replaced about 6 pieces of glass on 
thermal panels and even that is such a pain in the butt I now recommend panel 
switchouts.  And thermal panels do not require nearly the functional perfection 
PVs do.  That said, this brings up a great point that PV manufactures and 
perhaps the industry needs to address.  Though not a commonality, PV panel 
breakage is inevitable.  I think the question best be turned over to the 
manufactures.  I can't see the answer coming from anywhere else.

Esteemed group:
 
I have a customer who called this week stating that their son hit a golf ball 
in the backyard up on the roof and shattered one of the solar modules. The 
system was installed in 2005 and the module is a Sanyo HIP-190BA19. I have not 
been able to find a replacement as most sites list the module as discontinued. 
The module is still functioning and I was wondering if anyone has taken a 
module to a glazier for a glass replacement? Any other solutions are welcome. 
Thanks.

Re: [RE-wrenches] FINALLY! A flashed solar thermal penetration option

Hi  Nick and All,
 
I was not able to look at the Zilla too closely, but we are keeping away from 
anything that has a gasket on it.  We are currently using Flat Jack and are 
loving it.  It is a bit spendy but seems bullet, or maybe I should say, rain 
proof.

Looks good! I haven't seen it in person but I did see a sample of their PV

I would appreciate any feedback from the group.

Re: [RE-wrenches] Stiebel Eltron SHW Collector condensation issue

[Solar Energy Solutions]

After 25 years of installing solar thermal panels, we have come to the 
unfortunate conclusion that they all suck.  We have had out of the box 
failures on all panels we have used... and we are a very, very, very small 
company.   We pressurize our solar thermal systems to 60-80 psi and let them 
sit for 3 days.  If they hold that pressure... like a ROCK, we complete the 
install.  What we find, as often as not, is some little piddly leak somewhere 
in the loop.  Micro holes are not an uncommon encounter in panels.  So, we then 
have to wrestle the solar thermal manufacturer into first believing their 
"infallible" product is leaking , "out of the box"  and then pay, out of OUR 
pocket the substantial labor costs for its replacement.  So far as I can tell, 
all solar thermal manufacturers warranty their panels for 10 years.  But, they 
only cover $100.oo in labor costs to replace a defective product.  This does 
not begin to cover our labor costs. 
 Consequently, I have started down the road, (without success so far) of 
demanding solar thermal manufactures to stand behind their products with a 5 
year $500.00 Labor warranty.  I have talked to a ton of solar thermal 
manufacturers and  they all say the same thing.  "Our panels are the 
best.   Our failure rate is less then 2%.  We warranty them for 10 years, but 
we only pay $100.00 labor to replace those that are defective out of the box."  
I can't even get the evacuated tube guys to stand behind their product with a 
decent labor warranty!
 
Perhaps if more than one solar Bozo stands up and  says, "Enough, we want a 
panel with a 5 year $500.00 labor warranty".  A manufacturer might see the 
competitive edge of being the first to do so.
 
Sincerely,

Hi David -
 
Doesn't sound fun. We experienced a similar problem with a 10-collector system 
with Schuco Slim-Vs about 3 years ago. The collectors had lots of condensation 
build up in them, especially during the rainy season. Schuco stepped up and 
gave us new 2nd generation collectors under warranty. The new collectors do not 
have the condensation problem. Apparently they redesigned the ventilation 
method. Generally speaking I like the Schuco product although now we're 
noticing a browning effect occurring near the in inlet and outlet pipes on the 
absorber plate on Slim Vs installed a few years ago. I have yet to deal with 
this issue.
 
It sounds like Stiebel is still working out their design. You'll probably want 
to make sure that they have it fully figured out before replacing the old 
collectors under warranty otherwise you might have the same problem!
 
Good luck with it.
 
Best, August

SHW Wrenches,
 
Our first experience with SHW flat plate collectors with a condensation issue 
on the inside of the collectors’ glass cover. The system has two Stiebel Eltron 
Sol 25 collectors (88” x 48” each) with a 82 gallon single heat exchanger 
insulated tank in the basement of the home, with a SOM 6 solar loop controller. 
System installed fall of 2008.
 
Condensation problem was first noticed by homeowner late last December. The 
collectors’ manufacturer, Stiebel Eltron, instructed us to watch and see if the 
problem resolved on its own. It did not. Stiebel then instructed us to drill 
small holes through the sides of the collectors near the top for venting and 
more holes through the sides near the bottom for draining the collector (see 
attached pdf for Stiebel’s venting advice). We did that in early May of this 
year. The homeowner called us back with the same condensation issue. 
 
Stiebel then sent a bag of plastic insert venting plugs that required us to 
drill out larger holes in the side of the collectors and pop these vent plugs 
in. Plugs appear to be an attempt at making more venting area while trying to 
keep the rain out. After we installed these plugs we still have the same issue, 
homeowner still sees condensation and poor performance from the SHW system. 
 
The homeowner is now asking for new collectors under warranty.  Have others 
experienced a similar SHW collector problem? And have collector manufacturers 
stepped up with new collectors?
 
Thanks,

Re: [RE-wrenches] Xantrex / Schneider recall update

[Solar Energy Solutions]

All,
 
It took 2  twelve hour days and several hundred miles but we got all of our 
replacement capacitors installed.  It was actually good to go out and see how 
our systems have fared after 5 years or so.  The found two things without 
exception.  All the systems needed their panels cleaned, and...we have yet to 
figure out a good way to label systems on the fly with something other than a 
Sharpie which definitely is NOT permanent.
  
On the paperwork don't forget to include the serial number for the replacement 
capacitor.  All of ours started a z100.
 
Just called Schneider to check up how things are going with our claim.  Talked 
to Allegra who asked if I had been set up as a vendor.  I go, "huuu".  She says 
it is her slip up and that she will pass on the additional paperwork needed to 
process the claim.  I asked if she could put her hands on the 12 claim forms I 
had sent them on the 11th of May.  She took my number and said she would be 
back in touch with me today.
 
Smile, smile, smile...

We received all our parts this week.
Step 1 - remove capacitor in photo with pliers.
Step 2 - install interposing daughterboard
Step 3 (surprise) -  install three additional brackets to keep the inverter
from jumping off the wall & strengthen the front panel from being blown off?

Including paperwork to be filled out for each site requiring signatures from
the customer and an unposted envelope to submit to receive reimbursement for

If you have a muni then it's possible, but I'd guess that with most 
investor-owned utilities they'd just laugh in your face. There are a few 
utilites out there that have done this- I think that Portland, OR and 
Seattle have this and we're working on it here in Orlando too.

[RE-wrenches] Xantrex / Schneider recall update

[Solar Energy Solutions]

Just got off the phone with Schneider Electric, formally Xantrex.  They said, 
"bla bla bla, yada yada yada" and they are hoping our parts will be in by the 
end of the month.

Re: [RE-wrenches] Value of PV system to a home

[Solar Energy Solutions]

Aah, the persistent and what I find irritating issue of solar and economic 
value. Simply and as calmly put as I am able, money isn’t the issue, because a 
simple arithmetic calculation of costs just doesn’t capture the relevant 
factors. Just like a car, TV, cell phone, couch, or whatever, the real payback 
is in having something that does something for you, not recouping the costs.  
Also, it's the Environment ... !
 
Sadly, I know this is an extreme view so please don't bombard me with arguments 
I have heard add nauseam for the last 30 years.
 
We did have a client who installed a 3kW and solar water heating system and two 
year into ownership had to sell his house due a job relocation.  In our area, 
Portland Oregon, the average time a house takes to sell is 5 months.  His sold 
in a month, at above market rate with folks courting him for the sale.  Wh 
Da... Go Solar!

Regardless of the valuation placed on a PV or SHW system, a "green" real estate 
broker I know tells me that in the current market, having either or both of 
those on a home significantly increases the chance of the home actually selling 
rather than sitting on the market forever.
It's hard to imagine that anyone really wants to sell their home into this 
market, but for those folks who must for whatever reasons, that's a big deal.

Re: [RE-wrenches] Roofers installing solar = creative, new installation methods

[Solar Energy Solutions]

Joel,
 
Our company cannot survive without selling an entire system.  When we help the 
unqualified and untrained we legitimize unsubstantiated pv businesses.  We get  
a dozen phone calls a month from folks wanting us to install their systems.  It 
is a rat hole and we have learned that not only are such ventures unprofitable, 
they are fraught with poor designs and a plethora of other hassles.  This whole 
thing reminds me of the Carter solar Gold Rush where, sure, a bunch of systems 
were installed, but look at the damage it did to the industry.
 
Respectfully,

Guys,
You're missing a business opportunity. Instead of complaining about roofers' 
bad work and competition, show the company owners photos of their screw-ups and 
your quality work. Tell him that he is a risk. Then offer to do their design 
and electrical installation (let them do the sales, roofing, and grunt work).

We have seen a lot of the roofing companies nibbling around the edges of solar 
installs lately. I have only seen a couple of installs personally, and they 
were far from what I would call professional or reliable. Not quite as bad as 
your example, but in one case they had used Romex to run the wiring down to the 
inverter, and not in conduit.

Hi wrenches:
   Have you noticed that roofing companies have recently been trying to sell 
solar?  One company thought of something that I had never considered.  Listen 
to this neat story.
   I was servicing a job today, where a roofing company recently removed and 
re-installed a PV array on a 12 degree sloped roof.  The funny thing is that 
the roofer didn't want to penetrate his new roof, so he and the customer 
decided to leave the panels sitting on the composition roof without any 
attachments to the structure.  They didn't think it was necessary!  
    Shortly afterward, the array slid down the roof, and a MultiContact 
connector came unplugged.  The customer noticed that his system was not 
operating, and called us to the site.

Re: [RE-wrenches] Schneider recall

[Solar Energy Solutions]

They are first looking for the UL listing number on specific inverters before 
they send out repair kits.

I believe that Schneider will send PB board swap-out kits to installers and
compensate installers for the swap-out. We are putting together a list of
all the GT inverters that we have installed since 2002 and will ask for
enough to cover the list, and if we have extra kts left over, we will be
able to send them back to Schneider.

I understand that almost every GT inverter is subject to this recall.  It
looks like we may have 30 or so to take care of.

So have you seen the widespread recall on the Xantrex GT and Sunpower SPRx
line?
Bulletin reports instances of the wiring cover blowing off the inverter &
suggests all inverters be shut down until a retrofit kit is available for
installation.
