Soiling impact on energy generation of high concentration Photovoltaic power plant in Morocco

In this paper, we are studying the effect of soiling on High Concentration Photovoltaic (HCPV) modules performance. We evaluate the electrical characteristics such as power and energy depending of the variation of dust thickness. The result indicated a 1,610 µm thick fouling layer has decreased the modules performance by 7.64 % for a period of one month. The study is also investigating the effect of module tilt angle on soiling. The results clearly show that soiling effect is present at any tilt angle, but the magnitude is evident: the flatter the solar module is placed, the more energy it will lose.
