Panels layout needs facing south
4.7 kw panels system was installed and facing North-West based on Tesla design. After some monitoring experiences we found our solar energy output was very low: 8kwh per day on December . Compared to the same 4.7 kw of neighbor, our system generated about a half. Contact Tesla for our panel layout need to be redesign to face South-East but no response !! Anyone have the same problem ?
