Here is a broader view of the data from our solar panels, usage by our house and electric car. Our emergency power backup solar generating system provides more than enough power for the car. The chart below shows the big picture. The system has been in operation for nearly twelve years. It was designed as an emergency power backup system, an emergency generator, for those times when the grid is down. It has functioned perfectly in that role while offsetting daily electrical usage.
Update
My new system generates more than twice the old one. Now, the system easily powers the house, including air conditioning, charges my car, and charges the Franklin Apower whole house battery to run everything at night or when the grid is down.
