Our daily energy production since September, 2010, when the panels were installed. Some days are missed because no one was home to record the data. The red curve is the expectation from a very simplified model. The points above the curve were relatively cool days when the panels were most efficient; low production occurred on cloudy days. The green points are for the second year. During the first year, our total annual production was 4150 kilowatt hours.
The rooftop array. The peak production has been about 2400 W from these commercial SolarWorld crystalline silicon panels.
