Abstract

Photovoltaic (PV) module is one of the most useful, sustainable and non-harmful product in the field of renewable energy. It offers longer service period for least maintenance cost. The elements of PV are abrasive, easy for designing, and their structure like stand-alone technique give production from micro to mega-power level. A 3D numerical system of PV module has been build up and solved applying FEM technique based software COMSOL Multiphysics in this article. The average solar irradiation and optimum tilt angle for six divisions (Dhaka, Chittagong, Rajshahi, Khulna, Barishal and Sylhet) in Bangladesh have been calculated. The effects of solar radiation, angle of inclination, ambient temperature, and partial shading on temperature of solar cell, electrical power and PV module's electrical efficiency have been investigated. It has been observed from the results that the greatest value of electrical power 15.14 W is found in Rajshahi for solar radiation 209 W/m2. The highest electrical efficiency is found as 12.85% in Sylhet at irradiation level of 189 W/m2. For every 1° increase of inclination angle, electrical power and electrical efficiency level devalue by 0.06 W and 0.05%, respectively. Results also show that the efficiency level is decreased from 14.66 to 11.32% due to partial shading area from 0 to 40%. PV module's electrical power and electrical efficiency reduce approximately 0.01 W and 0.01%, respectively due to every 1°C addition of solar cell temperature.
