Xiamen builds 17 rooftop photovoltaic plants in six months
In the summer, air conditioners and refrigerators are essential for daily life. While enjoying the cool, many people feel uneasy about their rapidly spinning electricity meters. However, this issue is no longer a concern for Li Yanquan, who lives in Tong’an, Xiamen. His home, both large and small, relies heavily on electricity—gate access is electronic, flowerbeds are automated, and even curtains operate electronically. With two villas, his monthly electricity bill used to reach as high as 5,000 yuan. But after installing photovoltaic panels on his roof, he not only stopped paying electricity bills but also started selling surplus power back to the grid each month.
Xiamen has seen a rapid rise in rooftop solar installations, with 17 projects launched within six months. The province's largest residential rooftop "power plant" is now part of this trend. One household reported saving between 5,000 to 6,000 yuan per month on electricity bills. In March, the Xiamen Electric Power Bureau announced its commitment to promoting clean energy, including solar, wind, and natural gas. Residents can now generate their own electricity and sell any surplus to the national grid.
On April 10th, Yang’s rooftop solar project near Zhongshan Park was officially connected to the grid, becoming the first personal solar power station in Fujian Province. A few weeks later, Li Yanquan’s 15-kilowatt system began feeding into the grid, making it the second-largest residential distributed solar installation in Xiamen. This scale is rare across the country.
Li Yanquan, now one of the largest privately-owned solar generators in Fujian, has ambitious plans. Last year, while renovating his villa, he aimed to create a smart home with fully automated systems. However, the high energy consumption of such a setup led him to explore self-generation. Initially considering solar and wind, he eventually chose solar after learning about the new grid-connected policy and falling prices due to the EU's anti-dumping investigations.
Today, his solar panels generate 70–80 kWh daily, totaling over 4,000 kWh in just over two months. He invested over 300,000 yuan, expecting a return within seven or eight years. His household uses around 50 kWh daily, and he sells nearly 30 kWh back to the grid at night. This has reduced his monthly electricity costs from 56,000 yuan to zero.
Encouraged by his success, Li Yanquan now helps others install solar systems. Friends who saw his roof became clients, and he plans to rent rooftops from factories and schools, generating power and then transferring the facilities to the owners. He also sees potential in parking lots, where solar panels can be installed on sheds without affecting parking.
Eleven households in a community shopping mall have also built rooftop power plants. According to the Xiamen Electric Industry Department, residents can choose to use all generated power, sell surplus to the grid, or mix both. The electricity sold to the grid is separately metered and priced according to national policies.
With an average of four hours of sunlight per day in Xiamen, a 3 kW system generates about 12 kWh daily. For a typical household using 10 kWh daily, this covers most needs. In July, Xiamen introduced a tiered electricity pricing system, making selling electricity to the grid more attractive. Previously, one kWh could be sold for about 1 yuan, though this may change soon.
Currently, 17 photovoltaic projects are under application in Xiamen, with 11 being residential. Each household invests around 55,000 yuan on average. These homes follow the "self-use, excess-on-grid" model, reducing their reliance on the grid and even earning income from surplus power.
Other notable projects include Sanan Electronics, Taikoo Aircraft, and Wuyuanwan No. 1 Residential Area, which have already connected to the grid. Wuyuanwan No. 1 is a pilot project that uses solar panels on rooftops to meet public lighting needs.
Xiamen SM City Plaza also joined the solar movement, with 10% of its daily electricity supply coming from solar. The project cost over 13 million yuan, with a 6.05 million yuan state subsidy, and is expected to pay off in five years.
While solar power offers long-term savings, it requires a significant upfront investment. For a 2.5 kW system, the cost is around 30,000 yuan, with a payback period of over ten years. Experts suggest that larger-scale installations are more cost-effective, and this model suits villa or self-built homes rather than urban apartments.
The electric sector recommends that entire communities apply for solar installations together, though coordination among residents remains a challenge. To set up a personal solar system, individuals must first apply to the power company, get an access plan, and complete construction before connecting to the grid.
Connecting to the grid is simple and free. Users just need to install a bidirectional meter and a controller, without additional wiring. As long as the system meets technical standards, users can apply anytime and start selling surplus power to the grid.
