A simplified approach for fundamental photovoltaic module performance analysis

This paper presents a simplified approach for fundamental photovoltaic module performance analysis. The performance analysis is based on monthly average solar irradiance data and photovoltaic module parameters obtained from manufacturer datasheet. The proposed simplified approach is capable to compute the photovoltaic module power output without the need of complex photovoltaic modeling calculation. It is based on the solar irradiance, module rated maximum power and a derate ratio. The performance analysis includes monthly power output in kW and kWh, yield, capture losses, fill factor, efficiency, sizing by kWh usage, sizing by site area and economy in term of cost saved per energy generated. It contributes as an easy to use pre-analysis tool providing quick fundamental assessment of photovoltaic module performance to assists the selection of photovoltaic module and compliment the full-fledged commercially available renewable energy design and analysis software.
