Used large solar panels are reaching a point, that they are almost cheap as metal roofing.
So I'm thinking about combining those two pictures into once concept.
I wanted to build a Carport for my RV (20x26 ft) for a while, I figure - could I just use large panels to cover the structure? Metal is expensiven and panels are cheap, while produce all the power I would ever need.
Call me crazy, but I'm working backwards from the space I want to cover - to figure out the amount of panels I need minimum lol.
Large panels are usually around 40 inch x 80 inches (3,3 ft x 6.6ft)
Excel tells me I would need 3 rows of 8 panels each. 24x Used Sunpower 435 - are selling for like $220 each shipped (full palette 27X), sometimes my local distributer has them in stock and I can pickup for $150. That's then roughly 10,440 watts for 8 rows or 11,745w for the whole thing.
Any ideas if Bifacials would be any better? The carport will be like 13-14ft tall to fit my RV underneath.
But I'm in Florida so our ground is usually green - not expecting much reflection.
