Just wondering what others have experienced as maximum and minimum solar output. We have a 12 KW system in Northern California (between Sacramento and Lake Tahoe) and our maximum monthly output in the summer averaged 58.47 Kwh per day and the minimum monthly output averaged 7.19 Kwh per day. Maximum output was in June and minimum is in December. Total output for the year was around 12,400 Kwh. Our yearly use was about 21,000 Kwh with maximum use of about 2000 to 2200 Kwh per month in December, January, February and June. We have propane as a heat source. We have some tree shading and our roof system is 1/4 facing South, 1/4 facing West and 1/2 facing East. We are on the PG&E EV-A rate and our cost for electricity last year was $840. My system has 4 sets of panels (4 inverters). I assume the shading and location of the panels is causing the big difference between Summer and Winter Output. I wonder what what the increase would be with micro inverters?
