I will be adding 2 possibly 4 if I can find the real estate SunPower solar panels over the winter layup. I know I'm getting ahead of myself but are products like 303 or 210 plastic cleaners OK to use on a flexible solar panel? Their manual says over the counter cleaners such as Windex can be used but I would never use Windex anywhere on my boat.
SunPower SPR-E-Flex-100 Flexible Solar Panel 100 Watt Monocrystalline
Their installation manual states:
Trained SunPower dealer or trained SunPower support personnel should inspect all modules annually for safe electrical connections, sound mechanical connections, and freedom from corrosion. Periodic cleaning of module has resulted in improved performance levels, especially in regions with low levels of annual precipitation; therefore, SunPower recommends periodic cleaning of the modules. To clean a module, wash its surface with potable, non-heated water. Normal water pressure is adequate. Some fingerprints, stains, or accumulations of dirt on the surface may be removed with over-the-counter cleaners (such as Windex® or equivalent), or with a 3% soap-and-water solution. Wet the module surface with the solution, let it stand for five minutes, and then wet them again and use a soft sponge or seamless cloth to wipe the surface in a circular motion. Do not use harsh industrial-strength cleaning materials such as aggressive chemicals, scouring powder, steel wool, scrapers, blades, or other sharp instruments to clean the module. Use of such materials will void the product warranty.
Thoughts?
