  1. Your using a string converter and micro-inverters maintain power output better. You are selling rather than leasing the system out. I decided to go with a micro inverter package. The monthly payments are less than leasing. They included a total monitoring system that includes breaker load consumption. in the house. The inspection has not occurred yet, but if that does not change, it is what I want.
