Therefore, resource endowment has a great impact on solar PV power generation. The stronger the solar radiation, the more obvious the benefits of the project. Moreover, the construction quality of the project per se is also the key to the efficient and stable performance of the power station.
The financial, energy and environmental benefit dimensions of distributed projects are the highest, the social benefit of village level projects is the highest, and the benefits of joint-village projects are the lowest. 3.3. Comprehensive benefits of different solar radiation resource areas
As solar energy is carbon-free and environmentally friendly, the environmental benefits that the project has are incorporated into the indirect economic benefits to evaluate the feasibility of the project more scientifically and comprehensively. Thus, the economic benefits can be expressed as follows. (1) 3.1.1. Power generation income
Although the initial investment cost is large, national policies such as tax preferences greatly mitigate the upfront costs, and the green environmental attributes of PV power generation will provide additional income for the project. The NPV of the project will turn from negative to positive over time.
According to the results of the sensitivity analysis, the proportion of household PV has a small influence on the project's benefits, but as rural areas in China account for a large proportion of the national total land area, the economic benefits of the project can be guaranteed to a certain extent.
The construction period of the project is six months, with exploration and design costs of $203.358 thousand and construction and installation costs of $4931.438 thousand. The project's operating life is set to 30 years, in accordance with “General code for energy efficiency and renewable energy application in buildings”.
