Correction Procedures for Temperature and Irradiance of Photovoltaic Modules: Determination of Series Resistance and Temperature Coefficients by Means of an Indoor Solar Flash Test Device

The comparison between I-V (current-voltage) curves measured on site and declared by the manufacturer allows to detect decrease of performance control degradation photovoltaic modules strings. On site, are usually obtained under operating conditions (OPCs), i.e. at variable solar radiation module temperature. OPC must be translated into standard test (STCs), a global irradiance 1000 W/m2 temperature 25 °C. correction STC estimate deviation power examined maximum manufacturer. A possible translation procedure requires two parameters: Rs’, internal series resistance, k’, corresponding coefficient. aim this work is determine parameters carrying out specific experimental tests as indicated IEC 60891. set brand-new was experimentally characterized determining their means an indoor flash device based class A+ AM 1.5 simulator. Using curves, several temperature, it being considered.
