The Effect of Electrical stress under temperature in the characteristics of PV Solar Modules

Abstract

The effect of electrical stress under temperature, in dark and light conditions, on the performance of PV solar modules was evaluated. The forward and reverse characteristics I-V and C-V of a commercial silicon solar module have been measured in dark and light conditions after 10 min for each dose of stress. Experimental evidence showed that different stress levels of reverse currents under temperature is confirmed to be a major degrading factor and result in affecting the performance, efficiency, and power of a solar cell and module. The paper contributes to the research on the adverse effects of reverse currents under temperature on the normal functioning of cells and solar modules.
