A total of 68 photovoltaic modules with a surface area of 111 m\({}^{2}\) and a total installed capacity of 17.68 kW can be installed through the rational use of the roof of the main control building. The photovoltaic system has a life cycle of 25 years and is estimated to generate a total of 468.7 MWh during this period. Figure 7 illustrates the monthly power generation during the first year, with April recording the highest generation of 2.33 MWh. Figure 8 shows the annual power generation of a building's PV system over its 25-year life cycle, with the first year generating 21.25 MWh. The economic analysis of photovoltaic power generation involves evaluating the costs and benefits of solar photovoltaic power generation systems, both quantitatively and qualitatively. This paper selects photovoltaic modules with a peak power of 260 Wp, costing 5 RMB/W, and a total installed capacity of 17.68 kW. The total investment, with component investment accounting for 50% of the total investment ratio, is 176,800 yuan. Table 6 provides specific data. Figure 9 illustrates the cost benefits of investing in photovoltaic power generation systems. The data show that the investment can be recovered after 13 years of operation.

The photovoltaic power generation system offers several advantages, including no depletion risk, no fuel consumption, and no pollution emissions. These advantages play a crucial role in achieving China's carbon-neutral goal. According to the Annual Development Report of China Power Industry 2022, Table 7 presents the calculated environmental impact of solar photovoltaic power generation systems and the effect of energy conservation based on the statistics of CO\({}_{2}\), SO\({}_{2}\), and nitrogen oxide emissions per unit of thermal power generation. In summary, this project has a PV module installation area of 111 m\({}^{2}\), a total installed capacity of 17.68 kW, and a system efficiency of 85.3%. The power generation in the first year is expected to be 21.3 MWh, with a total power generation of 468.7 MWh expected over 25 years. The investment required is 176,800 yuan, with an income of 328,100 yuan. Additionally, the project is expected to emit approximately 267.3 tCO\({}_{2}\).
