Design of rooftop photovoltaic power generation system of a 100kW commercial complex

In this paper, the design of a 100kW commercial complex rooftop photovoltaic power generation system, photovoltaic module selected YL-260P-29b polycrystalline silicon cell, 23 series 17 parallel, inverter selected Solis-50K-US-F-LSW four-way input inverter. The inclination Angle of the photovoltaic square was designed to be 40°, and the azimuth was due south. Based on the calculation and simulation of pvsyst software, the power generation of the system in the first year was 153MWh. By setting the annual decay rate of the system, the replacement emission of carbon dioxide in 25 years was 2561.2 tons, it had good economic and environmental benefits.
