Comparison of Performance between Bi-facial and Mono-facial 10kW Photovoltaic Power Systems

Abstract

This paper is based and written on performance analysis of a 10kW Grid-connected solar power system with a comparison in integration of bifacial photovoltaic systems vs mono-facial photovoltaic systems. Thus, all these tastings were carried out on computer simulations using PVSyst6 software & MATLAB/Simulink. These simulations were done considering different albedos and tilt angles in order to identify power variations under different environmental conditions. The selected panels used monocrystalline type-high efficiency cells, both in bifacial and mono-facial and therefore, the technical parameters of both cell types will be the same in operating conditions. With the results obtained, it has shown the power gain in ground mounted-grid connected bifacial solar system is 23% more than the mono-facial solar power system and using these details, the researcher proposed a table that represents, most suitable PV panels for different site conditions.

Evaluation of the impact of the main parameters affecting energy performance in bifacial photovoltaic modules in a tropical location.

“…The growth that bifacial technology has had in recent years and the little knowledge we have about its performance has led to different studies being carried out in the world to understand how parameters such as albedo, inclination, height, and separation between sheds (pitch) affect its energy performance. The results of these studies [14][15][16][17][18][19] have shown that bifacial technology can obtain up to 30% more energy compared to monofacial technology. However, in tropical sites bifacial technology has not been well studied and it is unknown under which parameters bifacial technology can perform better, therefore, this research focuses on evaluating and comparing the energy performance of bifacial technology with respect to monofacial technology according to 4 main parameters of affectation: 1) inclination, 2) pitch, 3) albedo and 4) height from the ground, in a tropical location.…”
