1. Introduction. Solar energy is a renewable and clean energy resource. It will almost certainly play an increasingly important role in the future energy network [1].The use of
The results show that the economic benefits of residential solar depend strongly on local electricity prices and energy mix. We find favorable economics in some regions with
Of this, (10 %), 741.3MW and 200MW are expected to be solar power installations and distributed solar PV, respectively. 20MW of the distributed solar PV target is from the solar rooftop
of residential buildings in rural areas of mainland China and calculates the area that can used for the installed capacity, and the power generation, and conducts a comprehensive analysis of
Residential solar photovoltaic (PV) installations have boomed in China over recent years. However, knowledge about the economic performance of residential PV investments is still limited. Therefore, this study attempts to make a complete economic assessment of residential PV systems at the county-level.

On the other hand, some economic analyses were conducted on residential PV systems in terms of cost using measures like levelized cost of electricity, breakeven cost or price, unit cost of electricity, or initial cost (e.g. Zou et al., 2017; Pillai et al., 2014; Holdermann et al., 2014; Denholm et al., 2009 ).
Domestic scholars’ economic analysis of photovoltaic system focuses more on the evaluation of its application effect, and the most commonly used evaluation indicators are initial investment and investment recovery period (Gong, Jiang, and Qian 2015; Li et al. 2023; Wang, Ju, and Gong 2016; Yan 2018; Zhang et al. 2021).
4.3. Social benefits Compared with economic and ecological benefits, there is relatively less discussion in existing literature on the social benefits generated by the application of rural residential photovoltaic systems.
As the initial cost of PV investments keeps declining rapidly, however, residential PV installations began to speed up gradually. The newly installed capacity of residential PV systems in China in 2019 is 4.2 GW p, which is just following the annual addition to solar PV capacity of the U.S., India, Japan, Vietnam, or Spain ( REN21, 2020 ).
