nice setup. After he converts over to all led lights he can sell power back on the grid. That looks to be about a 12 panel setup with a power wall for connection and distribution through existing power panel. About $20k start up costs looks like to me. Should be getting about 15k on an average day sunny day, all day long. Great for the climate and the plants too. Why store power when you have to maintain the battery pack, plus they are expensive. Wait for Elon Musk and he will have cheap batteries soon from Nevada desert. nce setup and grow bro. peace
