| Popis: | 23rd European Photovoltaic Solar Energy Conference and Exhibition, 1-5 September 2008, Valencia, Spain; 3152-3159 As the word photovoltaic describes the light used to produce electricity, photovoltaic technology generates electricity from light. The greater the light intensity, the greater the flow of electricity, thus shading is critical. Minor shading can result in a significant energy reduction. Tilting the panel could definitely be a solution one might think! The tilting motion allows the build up of fine sand to be blown off from the array’s surface. However, gradually with time, dust particles tend to accumulate at the edges of the panel making it incredibly difficult to thereby simply float off by a passing breeze and thus affecting the overall efficiency of the solar panel, thus periodical cleaning of PV generators seems to be necessary. In this research work an original method to reduce the effect of wind blown sand and dust on photovoltaic arrays is described. The proposed method is based on the use of small DC fans that can be attached to the solar module and help in reducing the dust accumulation on the surface of the module, hence improving its efficiency. |
