Studying the weather condition affecting on solar panel efficiency
Solar energy is one of the most widely used types of renewable energy. Solar panels are more used, but weather factors affect their efficiency. In this research, some factors affecting the efficiency of solar cells were studied. A solar cell of single crystalline silicon have been used. The theoretical efficiency of this cell was about (16.276%), and the practical efficiency of the solar cell itself was calculated when the weather was Cloudy and its surface moistened with rain water, its maximum efficiency (8.5258%). As for when its surface is dry in the same conditions, its greatest efficiency is (14.5703%), and when the atmosphere is clear and the cell surface is covered with dust, its greatest efficiency will be (8.9502%).
