Analysis of albedo effect in a 30-kW bifacial PV system with different ground surfaces using PVsyst software

Abstract

Today, electrical energy is used extensively worldwide, increasing importance in almost all business sectors. For this reason, how to produce electrical power from earth sources is so important. Renewable energy sources that do not damage the environment and do not cause greenhouse gas emissions are increasingly used in electrical energy production. Solar energy, also renewable energy, is an excellent choice for the world's future because it is durable, abundant, low cost, recycling, and clean. Efficiency in solar energy is essential in terms of reducing resource use. The efficiency of solar PV modules depends on their structure, irradiance, and temperature. The albedo effects are significant in the bifacial modules because of the reflection of direct and diffuse irradiances. In this paper, the Albedo effect, and the surface's reflective power, are analyzed in a 30-kW bifacial PV system making simulations with PVsyst software. With different ground models and albedos, the PV system is simulated under given conditions using the PVsyst software. After results are compared, it is understood that the albedo effect brings about a severe power increase in bifacial PV systems compared to mono facial PV systems.
