Effect of Dust on Output Power of Conventional Solar Panels in Bangladesh
There is a recent upsurge in the usage of renewable energy resources. Among renewable resources solar energy is the main contributor in the power generation in our country. Efficiency of existing solar panels is reduced due to many factors due to which the rated efficiency cannot be achieved. Dust on solar panel is one of the main factors that reduces it efficiency. Dust is barrier between sunlight and solar panel. In this paper we have discussed a method to improve the efficiency of a solar panel by removing the dust from its surface. It was found that efficiency of solar panel is improved by using dust cleaning method. The experiment was carried out using two solar panels having same rating. Dust from the surface of one panel was cleaned regularly and another one was kept as it is. The measured power was found to be higher at the panel that was cleaned regularly. Experimental data and results are discussed in details.
