Solar cell and module manufacturer DAS Solar has entered into a strategic cooperation agreement with China Huaneng’s Clean Energy Technology Research Institute (China Huaneng CERI). With this signing, the 2 parties aim to advance PV technology innovation and conduct outdoor performance validation. The partnership will utilize China Huaneng’s test sites in Gansu, Shandong, Inner Mongolia, and Hainan to evaluate DAS Solar’s DAON modules, lightweight modules, flexible mounting systems, and smart shutdown technology. The field tests will assess product performance under extreme cold, high temperatures, high humidity, low irradiation, and high salinity environments, supporting technological advancements and optimized product selection for PV projects.
DAS Solar recently announced that it has started developing the national electronic industry standard Flexible Crystalline Silicon Solar Photovoltaic Modules (see China Solar PV News Snippets).
Power product manufacturer Hangzhou Kelin Electric (KLEC) plans to issue A-shares to raise up to RMB 1.46 billion ($201.65 million). Of the proceeds raised, RMB 1.261 billion ($174.19 million) will be allocated to a 1 GW high-efficiency perovskite solar module plant and the remainder for working capital. The project, to be executed by its subsidiary Keneng New Energy, will be constructed in Hangzhou City, Zhejiang Province, with a 48-month construction period (see China Solar PV News Snippets). KLEC emphasized its established partnerships with major utilities such as State Grid and China Southern Power Grid, ensuring demand for the facility’s future production capacity.
Heterojunction (HJT) manufacturer Grand Sunergy’s subsidiary has signed a strategic cooperation framework agreement with perovskite maker Phenosolar. The collaboration will focus on advancing perovskite and perovskite/silicon tandem cell technologies. Grand Sunergy will contribute its expertise in HJT cell production and perovskite/silicon tandem mass production, while Phenosolar will leverage its technological expertise in perovskite materials, including self-assembled monolayers (SAM) and inkjet printing processes. With this partnership, the 2 companies aim to accelerate the commercialization of high-efficiency solar tandem cells and modules.
Ningxia’s Development and Reform Commission has released a draft policy on distributed PV project development, marking the 1st provincial-level implementation guideline following the National Energy Administration’s Distributed Solar PV Development and Construction Management Measures published in January 2025. This policy categorizes distributed PV management by scale:
Residential PV (≤10 kV grid connection, ≤6 MW capacity) can opt for full grid feed-in, full self-consumption, or surplus power feed-in.
Small-scale commercial and industrial (C&I) PV (≤10 kV grid connection, ≤6 MW capacity) must prioritize self-consumption, with a minimum 30% self-use ratio for projects built on public institutions and 50% for projects on other C&I rooftops. Excess power exceeding these thresholds will not be compensated.
Large-scale C&I PV (≤35 kV grid connection, ≤20 MW capacity; or ≤110 kV grid connection, ≤50 MW capacity) should primarily adopt full self-consumption. However, surplus power feed-in may be allowed when Ningxia's electricity spot market becomes fully operational.
Additionally, the policy also classifies agrivoltaics, solar-fishery complementary projects, and small-scale ground-mounted PV projects under centralized PV plant management.
Leading cement manufacturer CONCH has commenced production at its 1,400-ton-per-day PV glass project. The project, part of CONCH’s integrated PV industry initiative, is located in Chuzhou City, Anhui Province, and includes 2 PV glass furnaces with 1,400-ton-per-day capacity and deep-processing production lines. With this PV glass facility, along with an integrated deep-processing system for quartz sand resources, CONCH aims to transition from a traditional building materials enterprise to a player in the renewable energy sector. Beyond PV glass manufacturing, CONCH is also developing renewable energy projects, with an installed capacity exceeding 900 MW.
