Abstract

In this paper the experimental study provides effects of cloud, temperature change, dust over the panel and tilt angle of Photovoltaic panel has been discussed and studies. This study is not for the hot summer but it is for upcoming winter i.e. from 1st of October 2014 to 30th of November 2014. Also the study over tilt has been made as maximum power is when the tilt angle is between 45∘ to 55∘as it allows maximum beam radiation to fall on the photovoltaic that provides the maximum power as output. While experimental study over temperature change on the photovoltaic the power is being effected as is shown in the graph plots of P-V and I-V curve for temperature change throughout the day. Study over temperatures at 28℃, 33℃ and 38℃ has been shown by the help of graph. From the results it is concluded that there is large power loss due to non-uniform shading area of cell or solar PV module in series connection but in the parallel connected PV module, there is no large power loss under the shading condition but it may be chance to circulating current due to variation of power but these circulating current blocked by blocking diodes.
