This paper firstly takes Zhongshan City as an example to analyze the feasibility of investment value of household rooftop PV power generation project under carbon trading mode. The results show that the current level of carbon price in Guangdong Province is not enough to promote residents’ investment in rooftop PV. Then, this paper further studies the impact of carbon price on the investment value of household rooftop PV power generation projects. The results show that the higher the carbon price level, the greater the increasing of investment value, and the level of government subsidy required is gradually declining. Finally, based on the research results, this paper puts forward two related conclusions and policy suggestions.
