Performance analysis of standalone photovoltaic system

The Electricity requirement of the world including India is increasing at an alarming rate. Several recent energy crises has forced the world to develop new and alternate method for production of electricity, since we so for not adopted due to various reason. Thus use of renewable energy is quite important. The performance analysis of a solar photo voltaic power plant is very important due to environment and economic benefits. Increase in the usage of standalone photovoltaic (SAPV) systems forces the better and even deeper understanding of factors that influence the performance of SAPV systems for better efficiency. Many researchers have analyzed the PV module in terms of panel modelling and I–V characteristics but in this works aspects that involve external conditions are not taken into consideration.This paper analyses performance consideration and factors that affect the performance of the SAPV such as effect of dust and shadowing. This paper also shows how these factors can lead to reduction in power output of Standalone Photovoltaic and cause a permanent degradation of PV cell.
