No not a clean energy discusion , clean panels!
Bird poop, dirt, dust it all gets on the solar panels.
One thing most people that own solar do not consider is how efficieny reduces with dirt and grime build up, sure if it rains often they can be self cleaning, but in the country dust is as common as cows mooing and oxygen!
When considering design of the solar apart from the gain from a north-facing panels, ground mounted panels had a few benefits, easy of cleaning to be one!
So with a little collected rainwater the panels can be cleaned easily to remove poop, grass and even dust build up to maintain a high level of solar power production using a simple window cleaner with extendable pole to reach the top of the panels.
Things you do for clean power 😉
