Analysis of Temperature effect on Power Productivity of Solar Panels in Residence Area

Solar panel temperature coefficient varies according to it’s industry, relates to the rate at which thepanel will under-perform at each increase in degree Celsius (?C). Majority of panels available here in Sudan for residential and agricultural usage are Poly-crystalline Chinese origin like A star have a temperature coefficient -0.4% /?C, when tested under standard laboratory conditions, where ambient temperature is set to 25?C. But in practical installations is found -0.025% /?C. The lower temperature coefficient, the better panel performance when the temperature rises. It’s important to chose the perfect solar panel technology for optimum performance at a given location considering the average temperature. This research study is proposed for performance variations evaluation of the solar panel during the day related to the temperature in Khartoum, Sudan. Field data of produced power of residence area A Star Chinese origin panel serve in designed Solar Panel system were collected. These data were analyzed and compared to the calculated results and with the installed solar panels ratings.
