Photovoltaic power generation has been done for a variety of sites. It is necessary to design the arrangement to consider the solar orbit dependent on latitude to increase the amount of light received by PV arrays. PV arrays can be packed into a site through arbitrary placement. However, this reduces the maintenance space for PV arrays. In addition, the shade created by front PV arrays reduces the amount of light received by behind PV arrays. Thus, packing PV arrays into a site is not the best solution. This study proposes optimization placement of PV arrays on arbitrarily shaped sites to maximize the amount of light received in arbitrary placement. The design variables of the PV array are the tilted angle, azimuth angle, and placement position of each PV array. The optimization problem to increase the total annual amount of light is solved using a genetic algorithm. The shaded area is calculated by ray tracing the sun rays. The effectiveness of the proposed method is demonstrated from several example analyses.
