Re: [RE-wrenches] Micro-inverters for 3-phase 220/127 in Mexico

2013-04-18 Thread Chris Mason
Do you think Enphase be willing to increase the VMax? That's what we do
here when we have 220V 3ph issues. As we are not US based, there is no UL
issue.
I have a project right now that Enphase is the best solution, but the
voltage would be 129v typically, so I would be unwilling to put in stock
units.

 a 225 kva transformer supplying 220/127 volt 3-phase to the property. They

Re: [RE-wrenches] Cleaning Modules

2013-04-18 Thread Benn Kilburn - DayStar Renewable Energy
Corey,
If rain water isn't doing good enough, which it usually does depending on
angle and other factorsŠ..

-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

Jesse,
Schletter PV Max is a great ground mount system.  Requires concrete
footers/pads.
when it comes to putting up the rack, it assembles very quickly.  And two
guys can easily mount 24 mods in under an hour. (just mounting, not wiring)

I cleaned my system in Palm Springs with rain-ex every 4 months. It did a great 
job and left a coating that keep the dust from sticking to the modules
I probably didn't need to clean it that often, but it was easily accessible. I 
put a garden sprayer on a hose to coat the panels after I cleaned them using
 a dust mop on an extension handle to remove any dirt. Each time they needed 
less cleaning. Rain-ex keeps the dirt from sticking.

We use a mild solution of Cascade dishwashing soap and a car wash brush.  We 
have been tempted by a product call Power Boost.

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

Greetings Wrenches,


I am wondering if anyone can offer tried-and-true tips for cleaning modules: 
tools, materials, methods?
