LIGHT ON PV SYSTEM

In today’s world as we have seen there is a lot of demand for renewable energy and their subsets. Solar PV is also one of the most powerful technology to deal with today’s energy crisis. So there is a tremendous development had already been done but still some problem we are facing in the field of solar PV installed on building or roof top. As we know for increasing PV performance on roof top there are so many factors responsible for that like inclination angle, orientation angle, dust accumulation, weather forecasting and many more.

There are so many factors which affects the performance internally and externally. Still many factors are there but we are not aware about it and thus constant degradation of PV module is keep on reducing the output power. The problem lies in how to identify and evaluate that important parameter and look for reasonable solution. PV module converts less than 15% of the solar radiation into electricity .thus the remaining incident solar energy is converted as heat energy which leads to cause undesirable short term and long term losses in PV module.The electricity produced by a PV system is directly proportional to the intensity of the solar radiation at the installation site and the positioning of the module with respect to the solar trajectory in the sky.
