Loading ...Yeah, the electric company ‘buys’ solar inputs at half what they charge for it. My leased Sunrun system is 3.5kw PV panels, a 7kw inverter, and 9.5kwh LG lithium battery. They are standardized ‘cookie cutter’ systems that will replace SOME (not all) of your electric usage at a monthly lease rate that is less than you would pay for the equivalent electricity from the grid. And the more the grid costs go up, the better the lease deal is for the juice received.
My system software and grid tie is capable of selling to the grid at off hours overnight if I have enough battery charge. But the system is biased to keep and use everything locally at the house. My electric bill notes that I sell them exactly 1 kwh every month… just to keep the billing system working. I use all the rest, and still buy some from the grid also. It varies with solar input days, but looking at my bottom line averaged monthly, it had reduced my electric bill around 60%… for half the cost.
