The installation of solar panels has a long-term impact on rural household income. Exploring how the installation of solar panels influences Rural Revitalization Strategy is of great practical significance. Based on the tracking data of solar panel installation of Y county of Central China from 2014 to 2019, this paper analyzed the impacts of the installation of solar panels on rural household income by a Difference-in-Difference model and discussed its influencing mechanism. Results show that rural household income increased significantly from 2014 to 2019, and the growth rate of per capita income for those households with solar panels was greater than those households without solar panels. The installation of solar panels has increased per capita income by 25.4%. Among them, agricultural operating income and property income increased by 74.4% and 444.5%, respectively. While wage income decreased by 45.3%. The installation of solar panels influenced per capita income by reducing off-farm employment hours, shortening off-farm employment spatial distance, and increasing agricultural operating income. Further analysis indicated that the installation of solar panels had a greater impact on wage income and agricultural operating income of those households in non-central villages than those in central villages, and the stronger household labor is, the greater agricultural operating income increase, the smaller wage income decline. Therefore, this paper puts forward the following suggestions: providing uniform solar panel maintenance services, promoting effective allocation of labor forces, distributing shares by a hierarchical strategy according to different labor ability, reducing the dependence on government subsidies for households with strong labor ability, encouraging innovations in the development mode of solar energy industry, and broadening income channels for solar energy industry.
