Solar Panel Output Less Than Expected
Just bought a house with an existing 5kw solar system. I reviewed past electric bills, showing the panel monthly output, and it’s lower than I would’ve thought. Around me, most calculators/maps indicate ~5hrs of useable sunlight per day average. That works out to about 750kwh/mo of production. The bills show half that amount. Am I misunderstanding something? Is something wrong with the panels? Or is it something to do with the orientiation? Due to house/roof design, 3kw are on the SE roof, 2kw on the SW roof. The SE roof is shaded by a taller neighboring house until mid-morning or so. Could that be the issue?
