With the introduction of the “dual carbon goals,” there has been a robust development of distributed photovoltaicpower generation projects in the promotion of their construction. As part of this initiative, a comprehensive and systematicanalysis has been conducted to study the overall benefits of photovoltaic power generation projects. The evaluation processencompasses economic, technical, environmental, and social aspects, providing corresponding analysis methods and datareferences. Furthermore, targeted countermeasures and suggestions are proposed, signifying the research’s importance forthe construction and development of subsequent distributed photovoltaic power generation projects.
