The present work focuses on sunlight conditions and environmental influence on photovoltaic (PV) solar modules. These modules are often exposed to very severe operating conditions that induce defects in the cells that constitute the module. Defects on the solar modules are modelled as shading defects, dirt or dust deposits, and others. The study showed the dependence of the overall module temperature on the solar insolation level. The photovoltaic module comprises 72 cells divided into six (06) groups of twelve (12). The theoretical study was carried out in the case of shadowing defects on photovoltaic (PV) solar modules. This work also showed the negative influence of shading on the electrical parameters of a module.
