| Abstract | Currently the value of photovoltaic (PV) modules is evaluated by power rating given by energy conversion efficiency under the standard test condition (STC), i.e., incident solar irradiance: 1kW/m2; solar spectrum distribution: AM1.5G; module temperature: 25?C; and the total area of the PV modules. The output power of the PV modules is greatly influenced by environmental factors which can change every minute outdoor. Thus, the evaluation at the one fixed condition cannot accurately rate the real value of the PV modules. Also, the impact of the environmental factors is different on different PV technologies such as crystalline Si and thin-film Si PV technologies. In this study, we demonstrate how to evaluate the output power of various kinds of Si-based PV modules under real working condition using contour maps. Also, we propose one of the promising methods for energy rating, which is the method for the rating of the PV modules by output energy in certain period and conditions, using the contour maps. |
