Benchmarking of temperature coefficients for two different manufacturers (poly-Si)

Measurement of I/V characteristic at different module temperatures to determine the temperature coefficient of PV module. The characteristics are recorded in the range of 25 to 65 °C, with an interval of 1 Kelvin and an irradiance of 1000 W/m². Temperature coefficients for power, operating current, operating voltage, open circuit voltage and short circuit current are reported.
