Temperature coefficient of solar panel

The temperature coefficient of solar panel indicates percentage of power output decreases due to rise of one degree centigrade with reference to its rating.

Conversion efficiency

The conversion efficiency of solar cell is affected by wavelength, recombination of holes and electrons, temperature and reflection.
