Aquavoltaic is an essential tool in overcoming the ground-based photovoltaic (PV) development barrier and achieving China's carbon neutrality target. After summarizing aquavoltaic technologies and global cases, this paper assesses the effectiveness of 292 aquavoltaic plants in China using the data envelopment analysis (DEA) method. Six essential input and output variables are included: installed capacity, power generation, occupied water area, construction cost, PV modules, and global horizontal irradiation to offer an appropriate measure of aquavoltaics efficiency in China. This study also performed correlation analysis for PV module type, PV mounting mode, and ownership based on a Tobit regression model. The results show that the efficiencies of China's aquavoltaics have improved significantly between 2014 and 2022, with the emergence and popularity of high-power PV modules playing a pivotal role. Furthermore, the regional study discovered provincial efficiency varies substantially. This paper also gives two reference indicators for new aquavoltaics in the future. • The global aquavoltaic technologies and cases were summarized. • The history and status quo of aquavoltaics in China were reviewed. • Aquavoltaics' energy efficiency has increased significantly in China. • The high-power PV modules have a positive impact on efficiency growth.
