After three days of work, the PV system is installed, connected to the grid, and producing power. This is a 4000 watt grid-tied system, estimated to produce an average 400 kWh/month. The system was installed using State of Ohio grant money combined with the remainder financed by my wife and I. 24 X Sharp 167 Watt panels and Sunny Boy 4000 Watt inverter. Installation by Dovetail Solar and Wind. I had wanted to do this myself, but in order to be eligible for the state grant money, it had to be done by a certified installer (which I am not!).
