Optimization of Electrical Power of Solar Cell of Photovoltaic Module for a Given Peak Power and Photovoltaic Module Area

摘要

In this communication, an attempt has been made to optimize maximum electrical power (i) for a given number of solar cells by varying area of photovoltaic (PV) module and (ii) for a given PV module area by varying number of solar cell. Analytical expressions for solar cell temperature and electrical efficiency of solar cell have also been derived for opaque and semi-transparent PV module. Numerical computations have been made for New Delhi climatic conditions with the help of MATLAB R2015a. Based on numerical computation, it has been observed that (i) an electrical efficiency is maximum for higher PV module area with lower packing factor for a given peak power of PV module (75 W_p) and (ii) an electrical efficiency is lower with maximum packing factor for a given PV module area (2.1 m~2). Further, an effect of different solar cell materials (i.e., m-Si, p-Si, a-Si, CdTe, CIGS, and HIT) on electrical power has also been investigated. It is found that electrical power output for m-Si and HIT is better than other solar cell material PV module.
