I had a whole thing about my setup here, but it was more than I want to share. Short version, panels are cheaper, easier to deal with, and longer lasting than you think. Most manufacturers guarantee 80% capacity after 30 years, area covered is more important than max output, there’s no need to buy the whole thing at once, 3-5k no more than 1200 at a time over a few years can get a lot of people all they need
