Evaluation of energy loss in solar panels in day-night circulation by MATLAB

Abstract

Fossil fuels as known as non-renewal sources which are mostly affect environment very adverse were extraction operations are costly which that the new-energy sources application is widely considered. The solar panels are the most effective devices for receive and control solar energy which focused on this study. The most important issue in solar cells is the problem of energy dissipation during day-night cycles. For this purpose, the particle swarm optimization (PSO) and perturb & observe (P&O) algorithms are utilized for evaluate the energy dissipation amounts were implemented in MATLAB. As basic of the analysis, Maragheh city's solar cells site is conducted to assessments. According to the results, the P&O method as well as PSO is suited for single-element solar radiation and for radiation/time response at tracking of maximum power point tracking (MPPT) were related to the day-night cycles.
