There are over 11,000 results related to distributed photovoltaics. How can the power grid with a high proportion of new energy manage peak loads during holidays? State Grid Zhejiang Electric Power has deployed a distributed photovoltaic aggregation forecasting feature on its control platform. This feature analyzes the distribution density of photovoltaics and performs voltage level topology tracing to accurately predict the output of distributed photovoltaics at the district level and on the 220kV main bus. By 2024, the accuracy of these forecasts is expected to reach 95.8%.

In a recent event, Huawei showcased an AI-powered industry solution at the 8th Digital China Construction Summit. Using a pilot case of distributed photovoltaic power prediction in Tongchuan, the Pangu large model combined with Ascend AI achieved an accuracy of 91.2%, which is an improvement of 6.2% over traditional methods. This integration is based on the power Harmony OS, which can unify the Internet of Things operating system and address terminal protocol fragmentation issues, ultimately reducing operational costs.

In Jiangsu, a new management approach for distributed photovoltaics has been released, allowing unlimited proportions of surplus electricity to be fed into the grid. This initiative strengthens safety management and addresses various challenges facing the development of distributed photovoltaics, instilling confidence in businesses, investors, and practitioners. In general, when using the self-consumption model for industrial and commercial distributed photovoltaic projects, there are no mandatory requirements for the proportion of self-consumed electricity.

On April 29, Yuexiu Capital announced changes in its senior management. Mr. Yang Xiaomin submitted his resignation due to reaching retirement age, stepping down from his roles as vice chairman, director, and general manager, along with his responsibilities in various committees.

In Shanxi, a new policy for distributed photovoltaics has been introduced, providing an additional month for compliance. The provincial energy bureau has issued a public consultation for the “Implementation Details for the Development and Construction Management of Distributed Photovoltaic Power Generation.” This initiative aims to promote the stable and orderly development of distributed photovoltaics in the province.

Recently, discussions about the electricity purchase price set by grid agencies have gained momentum, impacting time-of-use pricing for users in regions like Anhui, Jiangxi, and Jiangsu. Adjustments to time-of-use pricing policies significantly influence industrial users, distributed photovoltaics, and commercial energy storage developers.

In 2023, the National Development and Reform Commission, the Ministry of Finance, and the National Energy Administration jointly issued a notification to ensure comprehensive coverage of renewable energy green electricity certificates. This establishes the green certificate as the only credential representing the environmental attributes of renewable energy, expanding its scope from onshore wind and centralized photovoltaic power to include offshore wind as well.

In Yunnan, the first photovoltaic project at a tailings pond has successfully connected to the grid. Located in Honghe Prefecture, this project operates under a “self-consumption and surplus electricity to the grid” model, establishing a clean energy microgrid system with an expected annual output exceeding 2,500 MWh.

In the first quarter, positive signals were observed in energy production and electricity consumption. Nationwide, 59.71 million kW of photovoltaic capacity was newly connected to the grid, with 23.41 million kW from centralized photovoltaic and 36.31 million kW from distributed photovoltaic systems. As of March 31, the total installed capacity of photovoltaic power generation in the country reached 945 million kW, marking a 43.4% year-on-year increase.

In Guangdong, a 5.99 MW rooftop distributed photovoltaic project has successfully connected to the grid. This project, constructed by JA Solar, utilizes the roofs of five buildings in the park, installing 12,150 high-efficiency monocrystalline modules.

In Heilongjiang, the provincial development and reform commission has announced the available capacity for distributed photovoltaic connections for the first quarter of 2025. This initiative aims to support the scientific and orderly development of distributed photovoltaics in the region.

On April 27, the Jiangsu Development and Reform Commission published a draft for public consultation on the “Zero Carbon Park Construction Guidelines.” This guide outlines the overall principles, construction content, and performance evaluation for zero-carbon parks, applicable to state-level and municipal-level development zones.

As the deadlines for new regulations approach, uncertainties loom over the photovoltaic sector. The upcoming influx of distributed photovoltaic projects and market policies is anticipated to reshape the landscape.

In the first quarter of 2025, significant photovoltaic installation data was released, showing that Jiangsu, Guangdong, and Yunnan led in new installations. The total newly connected capacity reached 59.71 million kW, with distributed systems contributing 36.31 million kW.

Recent success stories in distributed photovoltaics demonstrate the sector’s growth, with multiple projects achieving full-capacity grid connections, further validating the capabilities of companies like JA Solar and Qingyuan Technology in this field.

With the backing of national policies fostering the development of distributed photovoltaics, companies are optimistic about the future of this sector.
