Guangdong Jiangmen: Guidelines for Distributed Photovoltaic Power Generation Projects Released
On May 13, Jiangmen City’s Xinhui District Housing and Urban-Rural Development Bureau issued a notice regarding the Guidelines for the Construction of Distributed Photovoltaic Power Generation Projects. The guidelines stipulate that the aesthetic control requirements for “photovoltaic + building” rural housing construction projects must comply with the Jiangmen “Photovoltaic + Building” Aesthetic Control Guidelines and Collection (First Edition). Site selection for “photovoltaic + building” projects should adhere to land spatial planning, and the buildings utilized must be legal and compliant. Furthermore, construction should follow classification control principles, ensuring that photovoltaic component coverage does not exceed the outline of the building’s main structure, with a minimum distance of 1 meter from the street-facing side in urban built-up areas.

Chongqing: Minimum Self-Consumption Proportions Set
The Chongqing Energy Bureau has issued a revised draft of the Implementation Guidelines for the Development and Construction Management of Distributed Photovoltaic Power Generation. The announcement states that projects within the main urban area of 22 districts must have an annual self-consumption ratio of at least 20%, while other districts must meet a minimum of 40%. Any special circumstances will require confirmation by the municipal energy authority in conjunction with the grid enterprise.

Xi’an, Shaanxi: Strong Support for Perovskite Development
On May 15, the Xi’an Municipal Government Office released a notice regarding the Implementation Plan for Supporting the Improvement of the Photovoltaic Industry Chain in Xi’an (2025-2027). The plan focuses on advanced photovoltaic R&D, manufacturing, and application, with a priority on improving the industry chain, enhancing quality and efficiency, accelerating technological innovation, and expanding new application scenarios in the photovoltaic sector.

Guangdong Boluo County’s New Policy on “Photovoltaic + Building”
On May 13, the Boluo County Government in Huizhou, Guangdong Province, released the Implementation Plan for the “Photovoltaic + Building” Application Pilot. The plan aims to establish a development model driven by government guidance and market operation by the end of 2025. It outlines that all new parks should achieve full coverage of distributed photovoltaic systems, with new public institution rooftops requiring at least 50% coverage. Additionally, the goal is to complete over 1,000 rural houses with demonstrable benefits and achieve an annual new installed capacity of no less than 70,000 kW. By 2026, the aim is to ensure that all qualifying buildings are equipped with photovoltaic installations, targeting an annual new installed capacity of at least 80,000 kW.

Shanxi Shuozhou: Key New Energy Projects Announced
On May 11, the Shuozhou Municipal Government released a notice regarding the List of Key Municipal Engineering Projects for 2025, which includes 2.47 GW of new energy projects—703 MW of wind power, 1,070 MW of photovoltaic power, and 700 MW of energy storage.

State Council: Carbon Peaking and Neutrality Included in Central Environmental Supervision
The notification requires all regions and departments to thoroughly study and implement the provisions of the Regulations, ensuring that each aspect is put into practice. It emphasizes the need for accountability in the construction of a beautiful China, maintaining a strict approach to ecological and environmental protection responsibilities, and enhancing the execution of the Central Committee’s decisions on ecological civilization construction.
