  Yeah, Travis, there are "excuses", dude. In the current issue of the 
Economist there's an article about wireless vs. wire-based telephone service. 
The US is only ranked 15th among developed nations in cellular coverage. I 
believe it's the same with internet. Private enterprise at work, dude, for 
better and worse. We can't all afford satellite (at $70/month?) if we haven't 
been served with good wired or wireless coverage.

   

  And after posting this short rant about cellular and wireless service in the 
US, I will note that Bruce Geddes is in Motueka, New Zealand. More power to 
Wrenches who don't live in LA and still read our posts!! Bruce is somewhere on 
the other side of the planet, likely surrounded by sheep, mountains, and sheep. 

   

  Peace, brother,

  Allan  (who pays $30/month for great high-speed internet through a 
community-based nonprofit high-speed wireless cooperative (www.lcwireless.org - 
check out the home page - hooray for nonprofit anarchy!) using two PV-powered 
access points (repeaters) I installed to bring it the 12 or so miles up into 
our neck of off-grid mountains well south of Santa Fe).

[Travis Creswell]

Please accept my apology not being aware of your unique situation and
realize that my tone was based on what I interpreted on an unnecessarily
less the friendly tone towards the poster of the pictures.

 

On a side note, I imagine the wrenches list is the least of your internet
problems.  How in the world are you able to do anything on the internet?  My
outrageously expensive and somewhat unreliable 1.6 MB connection via
satellite is almost too slow for most of the web now a days.  The very
instant I have another option I'm getting off of satellite.

 

Peace, Travis

Thanks for the tip William.  I am using MS Windows Mail on Vista and I can not 
see any option for that action in the setups.  Maybe it is hidden somewhere.

I am investigating another satellite BB option that has recently come available 
but until they come out to check I don't know if it is going to work.

Thanks,
Bruce

Travis,

Evidentally you didn't read the last sentence about *not by choice*. I'm 
sure there are still some parts of the U.S. that aren't served by broadband, 
sometimes it just not feasibly possible.

I'm sure some of the Ozark hillbillies would be glad just to wear shoes, let 
alone have a POTS phone.

We've done mounts like this before, when the roof was too sketchy to  
mount to, or an off grid system with a roof not facing close enough  
to south. It works pretty well: no penetrations or loading on the  
roof, still allows one bolt  tilt adjust,  azimuth to due south  
regardless of building orientation, etc.
We normally would sit the pole in concrete, and then attach it with  
unistrut to the wall in a couple of spots. The unistrut would be long  
enough to catch 2 or 3 wall studs, and then attach to the pipe with   
a 6" unistrut  clamp.
As better roof mounting products have become available, we have been  
moving away from this method. Also, Grid tie just isn't near as  
critical for panel orientation, where as a small off-grid system in  
the winter really needs to be tilted to at least 30 deg, and within  
20 deg of south to work right.
Funny teaching us old off gridders to quit tilting, etc. with grid  
tie. Bill Brooks had some humorous examples of off grid sensibility  
applied in very ugly fashion to grid tie systems. At some point, I  
think NABCEP should consider separate certifications, as Off grid and  
grid tie have such different design requirements.

I don't have a photo, but have seen a pole mount, in the ground, run  
up the side of the building, supported by the building by a bracket,   
which can mount a tracking or non tracking pole mount.


I have seen a pole mount ( don't recommend this) that was mounted  
through the house.  One interesting drawback was a lot of noise from  
the tracker motor through the metal pipe and walls.


Just a few other ideas.

at equinox.  Rack to be 3 sets of 3 modules each on two rails.


Every time I have tried this it is heavy and very difficult to do.

Re: [RE-wrenches] Seasonal Adjusters

[Allan Sindelar]

I have taken the opposite approach. Keep in mind that we have sunny winters,
so angle makes a real difference; if the system is well designed the gennie
only runs a few times in winter during storms. 

I strongly recommend pole-top racks, because it gets seasonal adjustment
down to a (usually) one-person job that takes 15 minutes twice a year,
because the rack is well-balanced over its pivot point. We make it as easy
as possible, with seasonal settings marked on the strongback with a center
punch. I recommend to homeowners that, unless they run low on charging
during summer, they set to winter angle (latitude + 15) around November 10
(halfway between fall and winter) and back to latitude on February 10
(halfway between winter and spring). Don't bother with a summer setting.

I like the new DP&W design and specify their racks. I never recommend UniRac
poletops.

I so totally agree - during the winter there's not enough sun to make  
a difference where we tilt the modules, and in the summer we dump  
power anyway so we've set them for a nice spring/fall angle and  
forgot about them for the last decade of so. The funny part is I  
spent all kinds of extra dollars on my racking so it could adjust it  
seasonally and through the day too. Never have done either with this  
racking simply not worth the trouble.

Re: [RE-wrenches] Seasonal Adjusters

[R. Walters]

This is a funny thread as I spend some of my time doing commercial  
installs in Hawaii, where tracking and tilt adjust is definitely not  
happening, and you're lucky to get the panels facing even close to  
south. The rest of the time though, I'm working with off grid  
customers that some may actually track azimuth manually by loosening  
the bolts on their top of pole rack.  Tilt adjust in New Mexico for  
off grid is pretty important, as we have short but intense winter  
days followed by lots of snow that doesn't slide off unless you have  
at least 40 degree tilt.


Also, I've run the numbers for Wattsun trackers with grid tie, and  
the economics pencil out in favor of tracking. (PV Watts lets you  
compare the benefits for your area)
If there is actually unobstructed area for tracking (very rare) I ask  
the customer if they're interested. If they seem mechanically  
inclined and like the idea, I might do it.
But if its a little old lady, who doesn't want to mess around, I set  
everything for a year round setting, and never look back.


BTW, I once tried Unirac's roof mount with tilt adjust: very flimsy,  
and hard to work with.

Re: [RE-wrenches] Seasonal Adjusters

[Dave Click]

The only system I've done with this feature, we used 2 Seas (now Iron 
Ridge, it appears) racking. I guess if you can limit those racks to 
being only two modules high, the weight would still be manageable. Still 
not something that one person can easily adjust, though.

I've been messing with DP&W racks and a ratcheting load binder 
(the barrel kind with eyes on both ends),
in place of the adjuster bar. I've also installed a greased thrust plate on top of the pole (under the cap) so folks who'd care to can adjust azimuth. Just make sure to mark solar south. (I use a center punch). sometimes I'll weld a flat bar or something fun to the cinch bolts. db

Re: [RE-wrenches] Seasonal Adjusters

[William Miller]

Darryl:

If this is a ground mount, I recommend a Direct Power top of Pole 
mount.  http://www.power-fab.com/tpmphotos.htm


The rack is supported at the center of gravity making a manual adjustment easy.

I need help designing or buying a seasonal adjuster.  I have a customer 
that insists on a seasonal adjustment.  They would like 30 degrees summer 
side of equinox and 50 degrees winter side.  Wants to adjust twice a year 
at equinox.  Rack to be 3 sets of 3 modules each on two rails.


Every time I have tried this it is heavy and very difficult to do.
Darryl

[RE-wrenches] Seasonal Adjusters

[Darryl Thayer]

He all
I need help designing or buying a seasonal adjuster.  I have a customer that 
insists on a seasonal adjustment.  They would like 30 degrees summer side of 
equinox and 50 degrees winter side.  Wants to adjust twice a year at equinox.  
Rack to be 3 sets of 3 modules each on two rails.  

Every time I have tried this it is heavy and very difficult to do. 
Darryl
