Which kind of gets to the heart of the problem: putting solar on dwellings is inefficient and really expensive. We provide incentives to make it profitable for some, but the benefits go to the people who need it the least. Why not just let any household invest up to $20k into a solar farm instead while getting the same incentives, etc? We would get ~3x more solar capacity for the money that way, and wouldn't discriminate against renters. Interest rates have gone up, but loans to cover the investment could be available the same as now.
