Solar panel formula
Solar panels are an unlimited source of free energy that produce no pollution. During daylight hours every panel provides the maximum power level, 60kW. Generated power will increase/decrease linearly during dusk and dawn, and no power is produced at night. This means one solar panel produces an average of 42 kW over one day and night cycle. - Download [PDF]

Calculating Solar PV String Size – A Step-By-Step Guide
For example, if you have a solar panel that has a Voc (at STC) of 40V, and a Temperature Coefficient of 0.27%/°C. Then for every degree celsius drop in panel cell temperature, the voltage will rise by: 40V x 0.27% = 0.108V. Or if your calculator doesn''t have a % sign. 40V x 0.0027 = 0.108V . Since STC is at 25°C, then at 24°C, the new Voc would be 40.108V. Some datasheets …
