Effects of High Module Temperature on Electrical Efficiency of Opaque Type Photovoltaic (PV) Module with Emphasis on Temperature Coefficient of Efficiency (TCE)

Saurabh Kumar Rajput

This paper investigates the influence of increasing module temperature on photovoltaic (PV) module’s parameters e.g. open circuit voltage, short circuit current, load voltage, load current, power and efficiency. The effect of variation in solar intensity on “temperature coefficient of efficiency” is analyzed as well. The results of calculations and experimental investigations are presented for opaque type photovoltaic (PV) module. Also the graphical representation of Reduction in efficiency and increment in module temperature with increasing solar intensity condition is shown.
