Seems like it's going to be a classic race to the bottom with regards quality of equipment. There's no way you could make it pay using best quality kit.
And check out the warranties on some of those cheap chinese/korean panels. They say they will replace unit if output drops by more than 20% but reduces the ammount by 4% per year they have been installed so if the performance dropped off after say 15 years you could maybe recoup 40% if your lucky.Where does that leave the customer?
It's a bit like cheap LED bulbs, is anybody really going to return them if they fail after say 20,000 hrs rather than the quoted 50,000. It's just not been thought through.
