I’ve been charging my model 3 at home off peak and noticed that the energy produced from solar is not sufficient enough to sustain. Let me share my story. 9.1 kW system installed in August last year with a promised minimum generation of 13000 kWh. I add all the monthly generation numbers from the solar city app and come up with ~14300 kWh. When I check the electricity bill, my one year consumption from 08-17 to 08-18 is ~8800 and net surplus generation is -700 kWh, which translates to a total of ~9500 kWh recorded . My question is: where did the ~4800 kWh difference go? Am I losing them in transit coming from the solar panels back to the grid?
