The total annual radiation on photovoltaic arrays is affected by the position of the sun and placement angles of a photovoltaic array that are included tilted angle and azimuth angle. In addition, it is also affected by the shape of the site and the position of photovoltaic arrays. The photovoltaic arrays generate electricity by aligned placement at the large-scale photovoltaic generation plant. On the other hand, in the case of the small-scale and complex shape of the site, there is a possibility that the aligned placement of photovoltaic arrays causes blank spaces in there. Therefore, these sites are expected to increase the total annual radiation on photovoltaic arrays according to the arbitrary placement of photovoltaic arrays. This study examines the placement optimization of each photovoltaic array at the site of small-scale and complex shapes. The placement parameters are used tilted angle, azimuth angle, and placement position of each photovoltaic array. The photovoltaic arrays with different placement parameters are optimized simultaneously by the genetic algorithm to maximize the total annual radiation of photovoltaic arrays. As a result, the photovoltaic arrays are arranged at sites of arbitrary shape, and the total yearly radiation of photovoltaic arrays was maximized.
