Shalini Garg, Arun J.B. . High Temperature Effect on Multicrystalline Photovoltaic Module in Western Rajasthan, India. Communications on Applied Electronics. 4, 2 ( January 2016), 44-48. DOI=10.5120/cae2016652055
The literature and research papers all show that PV (Photovoltaic) module have maximum efficiency at 25°C. However on analysing the real time data of a 5 MW (Mega Watt) PV (Photovoltaic) power plant located at Ramgarh, district Jaisalmer, India, it was found that the DC output voltage of a multicrystalline module is not maximum at 25°C, instead much higher DC voltage is obtained at 40°C ambient temperature and stable voltage is obtained only if ambient temperature is greater than about 37°C and panel temperature is greater than 50°C. DC output voltage decreases slightly with increase in panel temperature only after panel temperature crosses 52°C but the output obtained even at 68°C is much higher than that obtained at 30-35°C panel temperature roughly corresponding to 25-28°C ambient temperature. Since the power output is directly proportional to the voltage, Western Rajasthan has a great potential to become a leader in solar photovoltaic.
