Abstract：The application effect of a rooftop distributed photovoltaic power generation system with an installed capacity of 1 300.94 kWp in a factory in Huizhou City is studied,with a focus on analyzing its economic benefits and carbon reduction benefits.By constructing a theoretical power generation prediction model and verifying the accuracy of the model based on the actual operation data of the first year.The economic indicators are calculated by using the full life cycle cost analysis method,and combined with the life cycle assessment framework,the publicly available carbon emission factors and regional power grid factors are integrated to quantify the environmental benefits.The results show that during the 25 a operation period of the system,the total predicted power generation can reach 34.652 8 million kWh,the net present value is 5.525 2 million yuan,the internal rate of return is 26.12%,and the dynamic payback period is only 4.68 a.The minimum life cycle carbon reduction benefit is 10 381 tCO2.This project is both economically viable and environmentally friendly,providing a reference for the large-scale application of rooftop photovoltaic systems in industrial plants.
