ANALYSIS OF ENERGY DISTRIBUTION OF PHOTOVOLTAIC MODULE UNDER NON-STANDARD TEST CONDITIONS

Electrical-thermal performance and power loss analysis of PV module are two hot issues in the field of PV research. However, the complex photoelectric conversion mechanism and the variable operating conditions pose great challenges. This paper develops a coupled energy distribution model for PV modules under non-standard test condition, integrating the five-parameter electrical mode, heat resistance model and loss model. The coupled model is verified by comparing simulated and measured electrical-thermal performance. Operating performance and energy distribution of the PV module under non-standard test condition is also discussed in detail. The results show that on a typical day, 21.9% of the incident solar energy is reflected, 14.3% is converted into electricity, and the rest（63.8%） is dissipated as the heat. More than half of these heat losses come from spectral mismatch losses, including sub-bandgap and thermalization loss.
