Abstract
A solar PV module operates with optimal efficiency only when it is run at its maximum power point. Furthermore, a number of factors, including panel temperature, load on the system, dust deposition, amount of irradiance from the sun, and direction of the sun, can affect the performance of the solar PV panel. There is a significant amount of research being conducted to improve the efficiency of solar power systems, particularly in the area of efficiency improvement by overcoming the aforementioned challenges. The main factor decreasing the effectiveness of solar panels is dust or shadow deposition, which must be addressed. The proposed experiment is an effort to examine how solar panels perform electrically in a variety of shadow or dust collection scenarios. The research indicates that the efficiency of solar panels is significantly reduced by dust or shadows that fall on them. According to the investigation, a solar panel’s output power and efficiency are decreased by 20% to 80% depending on how thick the dust accumulation is.
