This article focuses on the performance of PV modules under partial shading, which causes a variation in the output power, and the module operating temperature. To reduce this effect, it is important to take appropriate action. The partial shading affects most of the hot spots in the PV module, resulting in total energy dissipation and cracking the solar module, which can reduce up to 10% of the total power of the solar module. Reverse current due to partial shade can be increased to a high temperature on the module. The analysis conducted shows that the hot spot of solar cell components in the concentration of the element is not uniform. This paper considers the internal heat generated due to shade cells and power loss. The use of a bypass diode model in PV module significantly improves the power and the operating temperature of the solar cell under partial shading.
