We've always wanted to go solar, but our house has too many huge wonderful trees. When we bought the little rowhome at the bottom of our block as a rental property, we realized that we could put solar on that roof, and through Virtual Meter Aggregation, could get credit for any excess solar generation at our own house up the street. The system produces 100% of the tenant's use and about 75% of our use. It's working perfectly. We love reducing our carbon footprint!
