[RE-wrenches] Cleaning Modules

[Solar Energy Solutions]

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
