Mathematical model for determining the performance characteristics of multi-crystalline photovoltaic modules

摘要: Mathematical models for predicting the performance characteristics of multi-crystalline photovoltaic (PV) modules have been developed. In any prediction electric output PV systems, an understanding its is fundamental importance. These are popularly expressed in form IV curves that may be presented graphically; or using equations. There exists many equations calculating photogenerated current IL, saturated I0 and a fitting-parameter a. The simulations experiments on conducted. To achieve this, experimental system 5 kWp capacity was set-up comprising 40 modules, arranged string combination 8 series by parallel. voltage data were recorded at various solar radiation levels module temperatures. This paper then presents discusses set new pertaining to a, I0, maximum power point. results graphs with constant values compared those obtained from set-up. could used predict performances points temperature only.
