Recent Developments
In the development of distributed photovoltaic projects, Haier New Energy has discovered that many rural areas, such as Gedangdian Village in Wuzhi County, Henan Province, face significant challenges with high heating costs and environmental pollution during the winter months. Local residents have a pressing need for clean energy heating solutions. Mr. Yang, a local farmer who installed Haier’s air energy system and photovoltaic power station, praised the system, stating, “After installing ‘Tian Guang Di Re,’ my winter heating costs are significantly lower than before. Additionally, the photovoltaic sunroom on my roof generates rental income that helps offset some of my electricity costs.”
Integration of Renewable Energy
On March 27, in Guiyang, Guizhou Province, efforts are being made to promote integrated development of wind, solar, water, and thermal energy while exploring pilot demonstrations for integrated photovoltaic residential buildings. This initiative aims to fully utilize rooftop resources and meet energy needs across various industrial parks.
Safety Regulations and Management
On March 26, the Development and Reform Commission of Xinyu City, Jiangxi Province issued guidelines for managing the development and construction of distributed photovoltaic projects. It is stipulated that rooftops deemed unsafe, such as those of steel structures or warehouses containing hazardous materials, are prohibited from hosting such installations.
Market Dynamics
With the beginning of 2025, two significant policies, the “Management Measures for the Development and Construction of Distributed Photovoltaic Power Generation” and the “Notice on Deepening Market-Oriented Reform of Renewable Energy Pricing,” have officially opened a new era for photovoltaic power generation in China, emphasizing volume and price flexibility. Notably, Aixu Co., Ltd. has introduced the “Sirius” and “Polaris” series of components, which challenge the industry’s perception that certain technologies are more suited for distributed scenarios.
Growth in Distributed Photovoltaics
As of March 25, in Ganyu District, Jiangsu Province, the number of distributed photovoltaic users has reached 33,600, primarily concentrated in rural areas with weaker economic and grid foundations. This growth is characterized by a reverse distribution pattern where the development of distributed photovoltaics is less prevalent in the west compared to the east.
Recent Projects and Initiatives
On March 20, Guangxi Province announced the procurement candidates for N-type component supply for various distributed photovoltaic projects. Meanwhile, the first “zero-carbon ranch” distributed photovoltaic project in Etokqi, Inner Mongolia, has been completed and connected to the grid, boasting a total investment of 1.3 million yuan with an installation capacity of 250 kW.
Policy Support and Future Plans
On March 21, Rao Ping, Guangdong Province released a pilot scheme for integrating photovoltaic applications with buildings, which includes provisions for electricity pricing and support for green electricity trading, aiming to enhance the economic viability of distributed photovoltaic projects.
Technological Advancements
Recent technological advancements have led to the standardization of distributed photovoltaic systems, with a focus on enhancing safety and efficiency. For instance, in Fujian Province, a resident plans to install a low-voltage distributed photovoltaic system with a capacity of approximately 40 kW, which is expected to generate around 50,000 kWh annually.
Conclusion
The landscape of rooftop distributed photovoltaics is evolving rapidly, driven by regulatory support, technological innovation, and growing market demand. The Polaris Solar Photovoltaic Network will continue to provide updates and insights into this dynamic field.
