Technical mapping of solar photovoltaic for the Coal City of India

Abstract

Performance of nine commercial solar photovoltaic (PV) panels from different manufacturers with combination of different manufacturing materials and technologies are studied under the environmental conditions of the Coal City of India. The results give an indication of the comparative performance of different PV technologies under the aforesaid location's environmental condition which helps to choose the best suitable PV technology for the Coal City of India. This procedure is commonly known as technical mapping of solar PV. Performance of PV panels made of Maxeon Cell Technology, heterojunction with intrinsic thin layer (HIT), mono-crystalline silicon (Mono C-Si), poly-crystalline silicon (Poly C-Si), Micromorph, SCHOTT, amorphous silicon (a-Si), copper indium gallium selenide (CIGS) and cadmium telluride (CdTe) technologies is analysed. Meteorological and PV panel parameters required for the study are collected from National Aeronautics and Space Administration (NASA) renewable energy resource website (Surface Meteorology and Solar Energy) and the data sheets of commercial PV panel manufacturers, respectively. The outcome of this study concludes that modules made of amorphous silicon technology perform better under the typical temperature variant and dry environmental condition of the Coal City of India. The same PV technology is also best suited considering life cycle assessment and global warming impact point of view for the concerned site.

“…Therefore, to evaluate the actual performance of a PV system, it is important to determine the operating temperature of the PV module. By knowing the ambient temperature of a particular location, NOCT (Nominal Operating Cell Temperature) of the PV module and the incident solar radiation at that location [71] the module operating temperature can be calculated as…”

“…The solar intensity (G) in the equation 1can be neglected and operating temperature can be calculated only by considering the ambient temperature of the location and specified NOCT [71] which is presented in equation (2). The deviation of the operating temperature from 25°C, results in changes of the power output of the module.…”
