In order to alleviate the pressure on energy consumption caused by the scarcity of land resources, a distributed photovoltaic power plant design combining BAPV (Building Afttached Photovoltaic) and BIPV (Building Integrated Photovoltaic) was implemented on the rooftop of the administrative building of a certain school in Guangzhou. The creation of a 3D model of the building's rooftop using SketchUp software was instrumental in optimising the layout of the photovoltaic power generation system. The final installed capacity was determined to be 436.36 kW, with 266.8 kW allocated for BAPV and 169.56 kW for BIPV. The photovoltaic power generation system was then simulated using PVsyst software. The findings indicate that the photovoltaic power generation system exhibits an energy efficiency ratio of 82.5 %, an average annual power generation of$409,448 \text{kWh}$, and a reduction in carbon dioxide emissions of$8,403.9$tons over a 25 -year period. The calculation of the grid connection benefits is based on a 70 % selfconsumption rate and surplus power fed into the grid. The average annual revenue is 236,000 yuan, with a total revenue of$5,898,100$yuan over 25 years and a payback period of 6.1 years. This design has been demonstrated to exhibit significant feasibility and environmental benefits in alleviating Guangzhou's land resource constraints and energy consumption pressures.
