Xiamen builds 17 rooftop photovoltaic plants in six months
In the summer, air conditioners and refrigerators become essential in daily life. While enjoying the cool, many people worry 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. Li Yanquan owns two villas, and his monthly electricity bill used to reach 5,000 yuan. But since installing photovoltaic panels on his roof, he not only avoids paying the bill but also sells surplus electricity back to the grid each month.
Xiamen has seen the rise of residential rooftop solar power plants, with the province's largest being a "power plant" for households. In March, one household could save up to 5,000 to 6,000 yuan on electricity bills. The Xiamen Electric Power Bureau announced in 2013 that it would promote clean energy sources such as solar, wind, and natural gas. Residents can now generate their own electricity and sell any surplus to the national grid.
On April 10th, Mr. Yang’s photovoltaic project near Zhongshan Park was officially connected to the Xiamen Power Grid, becoming the first personal solar power station in Fujian Province. A month later, Li Yanquan’s 15-kilowatt system was integrated into the grid, making it the second-largest individual residential photovoltaic power station in Xiamen. This scale is rare across the country.
Li Yanquan is enthusiastic about solar power. As the largest privately owned distributed photovoltaic generator in Fujian, he has ambitious plans. Last year, while renovating his villa, he aimed for a "smart home," which required significant energy. After learning about self-generation, he explored solar and wind options. With the introduction of a grid-connected policy and falling PV module prices due to EU investigations, he opted for a photovoltaic project.
Today, his panels generate 70-80 kWh per day, producing over 4,000 kWh in 60 days. He invested over 300,000 yuan, expecting a payback in seven to eight years. His household uses 50 kWh daily, with nearly 30 kWh sold to the grid at night. This saved him 56,000 yuan monthly from two villas.
Inspired by his success, Li Yanquan now helps others install solar systems. Friends were impressed by his roof and became clients. He plans to rent factory or school roofs for photovoltaic projects, aiming to generate income by investing and then transferring ownership. A square meter of roof space costs just 1 yuan annually, making it an attractive investment.
Eleven households in a community shopping mall have installed 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. Electricity from the grid and the solar system is separately billed, following national policies.
In Xiamen, the average daily sunlight is 4 hours. A 3 kW system generates about 12 kWh daily. For a household using 10 kWh per day, it meets most needs. In July, Xiamen introduced new electricity pricing tiers, with higher rates for excessive usage. Before, selling 1 kWh to the grid could earn about 1 yuan, though this may change soon.
Currently, 17 applications for photovoltaic projects exist in Xiamen, with 11 being residential. Each household invests around 55,000 yuan. These homeowners use spare roof space for solar panels, adopting the "self-use, excess power-on-grid" model. They no longer pay for their own electricity and sell surplus to the grid.
Other entities like Sanan Electronics, Taikoo Aircraft, and Wuyuanwan No. 1 Residential Area have also connected to the grid. Wuyuanwan No. 1 is a pilot project, with solar panels meeting public lighting needs. Xiamen SM City Plaza joined the trend, generating 10% of its daily electricity through solar, with a 5-year payback period.
While not all households can afford the initial investment, the model suits villa owners. Experts note that solar panels in urban areas are not practical due to limited space. Community-wide installation is suggested, but coordination among residents is challenging.
To set up a personal power generation system, citizens must apply to the electric company. Once approved, they can hire design and construction teams. After completion, the power company installs meters and signs contracts. Grid connection is straightforward, requiring only a controller and bidirectional meter.
With growing awareness and supportive policies, more households and businesses are embracing solar energy, turning rooftops into power generators.
