Shading of a Cell in a Module. An individual solar cell has an output of 0.5 V. Cells are connected in series in a module to increase the voltage. Since the cells are in series, the current has to be the same in each cell and shading one cell causes the current in the string of cells to fall to the level of the shaded cell.

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 will give the temperature coefficient in mV/°C. In this case you can convert to %/°C by dividing the mV/°C figure by the …
