Performance of 20w Solar Photovoltaic Module for Energy and Exergy Analysis

Abstract

The solar photovoltaic system generates both thermal energy and electrical energy by utilizing solar\nenergy. In this paper an experimental attempt has made for calculating energy output as well as exergy\noutput of solar PV panel installed at R.L.J.I.T. Bangalore. Energy and exergy analysis was performed by\nusing first and second law of thermodynamics to evaluate energy and exergy. The framework involved in this\nprocess are ambient temperature, overall heat transfer, open-circuit voltage, short-circuit current, fill factor,\nsolar radiations etc. It is predicted that temperature of pv solar module has most effect on the efficiencies. By\nthe help of water or air the heat can be removed to improve both energy and exergy efficiencies.
