Abstract
Photovoltaic energy has many advantages, for instance, it does not pollute the environment, it has a large availability around the world, and in general, it is reachable by all the countries. However, this energy source has its performance affected by external and/or intrinsic parameters. Therefore, this study intends to analyze, via computer simulation, the shading and inclination angle influences on the photovoltaic module performance, acquiring the characteristics curves I-V and P-V using the software PV*SOL. Besides, the electrical efficiency in different configurations of shading and angles were studied. Analyzing the simulations, it is observed that the PV module tilted at 15° exhibited superior overall performance during the day, presenting the best results of dissipated power in a resistive load of 150 Ω. When there was shading on the PV module surface, it is verified a significant and proportional reduction of electrical power and maximum current, resulting in 1/3 maximum power reduction when 1/3 of the surface is shaded.
