The rooftop of Hefei Shanshan Outlet Mall was utilized to build distributed photovoltaic power generation and related supporting facilities. The grid connection mode adopted was "self-generation for self-use, with surplus power fed back to the grid", and the annual average power generation was approximately 2,067,100 kWh. This project can generate a large amount of clean electricity annually, reducing reliance on traditional fossil energy and lowering greenhouse gas emissions. It helps improve the local environmental quality and contributes to the achievement of energy conservation and emission reduction goals.
