Dust and dirt can block sunlight, causing a reduction in solar panel efficiency by up to 6%. Regular cleaning can restore up to 95% of original power after maintenance. . Solar power is an efficient, eco-friendly energy source. Solar panels convert sunlight into electricity, but dirt can significantly reduce their efficiency. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the. . In recent decades, the use of photovoltaic (PV) modules as a source of electricity has grown significantly, driven largely by government incentives and regulatory advancements. However,depends on module design,installation and environment,each hotovoltaic panel has different level of performance.
