Abstract

This article compares the actual wasted power cost of the three maximum 12 MW solar farm projects with different shapes: Trapezoidal shape Rectangle shape and polygon shape In the same area of the Solarco project Installed in the area of Bang Len District, Nakhon Pathom Province by comparing the calculated loss power factor from the actual measured panel temperature. This is the panel temperature influenced by the wind blowing from the north and south side. Other factors such as sunlight, ambient temperature, and wind speed were assigned the same values for all 3 projects. Data was collected for 365 days or in the year 2015 at 06:00 a.m. - 06:00 p.m., finding the difference in shape by the centroid method and comparing the wasted power of each project. It was found that the shape with the highest point position on the horizontal plane. The power loss is less than the shape with the position of the point on the vertical plane. When influenced by the wind blowing from the south Therefore, a rectangular shape with a point position on the horizontal plane that is greater than that of a trapezoid shape and polygon shape installed in the same area Therefore, the energy loss due to the least heat is 7.22 percent less than the trapezoidal shape and polygon shape. The power loss was 9.44 percent and 8.43 percent, respectively.
