Performance Analysis of Polycrystalline Silicon PV Modules on the basis of Indoor and Outdoor Conditions

Abstract

This paper summarizes the electrical characteristics of two Polycrystalline silicon PV Modules. Tests are operated in outdoor exposure and natural sunlight located in Gurgaon Region of Haryana (India) as specific composite climate environment, characterized by high irradiation and temperature levels. PV modules performance evaluation was performed according to International Standard as diagnostic test of data, manufacturer. Data acquired by Environmental Operating Conditions (EOC) was converted into Solar Module Output characteristics at Standard Test Conditions (STC) by using method suggested by A.J. Anderson and G. Blaesser. Then, based on the investigation results of the conversion equations, these methods of translation are distinguished by the type of Solar cell Technology and the application range. A difference between the tests in indoor situation and in natural environment exists, attributed to various factors including effect of spectral changes over time, module temperature, effect of reflection by PV incident angles and also light induced degradation in crystalline silicon.
