An optimum layout scheme for photovoltaic cell arrays using PVSYST

Abstract

The layout scheme of photovoltaic cell arrays has the most significant impact on the total power generation in a large photovoltaic power plant. Here, a simple optimum layout scheme for single-axis tracking photovoltaic systems using PVSYST is proposed. First, the photovoltaic array reference spaces in north-south and east-west orientation are determined following the actual engineering experience. Then, using the power generation capacity of unit cost as the optimization function, the photovoltaic array spaces are meshed twice to obtain the optimization parameters. A real example was given to show the specifics of the method
