Wife wants Solarworld as they are American made, I am not as particular as I doubt many panels have been up for 25 years yet to prove their durability. Definitely want micro-inverters, leaning toward the Grape systems that Costco sells, but there are no reviews which I find strange. I know they will custom design a system for a good price. I’m thinking 5-5.5 KW should keep us out of tiers 3 and 4. Never even considered the roof because it looks good, but was up there last week measuring pitch and noticed the composite shingles are definitly harder that I thought they should be.
