Here are a few options, and Rain-X ISN’T one of them. (It washes off after a few rains! Yeah, so does bird do.) haha
“Let it snow, let it snow, let it snow.”
Interested in adjustable roof racking? Active Solar Power enthusiast, those individuals who tinker with their system may chose to install adjustable racking. During the winter months an adjustable rack would allow you to take advantage of the suns winter positioning.
Wow, this article was written in August! “Snow? You want to talk about SNOW?!”
This is due to the albedo effect, which is the diffuse reflectivity, or reflecting power, of the surface. The whiter the surface the more sunlight is reflected off it (it is for this reason that skiers can get snow blind, and badly sun burnt when out on the mountain).
But if you’re so inclined…
“On Wednesday morning, I was prepared. A week earlier, I had bought a snow rake. (These are hot items this year given all the snow and problems with ice dams.) A snow rake–the one I bought was about $75–is just a flat aluminum plate with a long handle. Run it down your roof and the snow comes off.”
“In heavy snowfall, the solar panels still give off heat, allowing the snow to begin melting above them. Houses with solar panels will avoid roof cave ins because of the dispersion of the snow due to the heat of the panels.
Snow falling off panels simultaneously cleans them and therefore boosts their power output.
On days when snow covers your solar panels, there is no need to worry about your output because your total energy is calculated throughout the entire year, meaning that variations in output during winter months are made up at other parts of the year.”
I wouldn’t advise using a rake to clean your panels, but I’d seriously think about some Rain-X.
Most people are especially concern about their electricity generation during storms because a utility’s outage usually means your solar power system may power down IF it has not been UPGRADED to, or DESIGNED as a BIMODAL or ISLAND-capable system. Contact your Solar Power Consultant, Contractor, or Installer and inquire about Bimodal and Island-capable Solar Power Systems.
