Abstract:

Formulas for calculating the array spacing of mountainous PV power stations mounted on slopes are derived, and the calculation formulas for the projection parameters of the PV arrays on the horizontal plane are given. A software for the layout of the PV power station arrays is developed. Taking the project located in the Gonghe, Qinghai as an example, the formula calculation and PVsyst software simulation results are compared and analyzed, and the accuracy of the formula is verified indirectly. The research results can be used to guide the calculation of array spacing and shadow analysis of PV power plants.
