China Solar PV News Snippets: Renshine’s 30×40 cm Perovskite Module Hits 20.84% Efficiency & More

Renshine’s 30 × 40 cm perovskite module achieves 20.84% efficiency

Perovskite manufacturer Renshine Solar has announced that the 30 × 40 cm flexible perovskite module, developed in-house, achieved a stabilized efficiency (MPPT) of 20.84%, as certified by the National PV Industry Measurement and Testing Center. The company claims this to be the highest stabilized efficiency record worldwide for perovskite modules of this size. It also reported that its mass-produced 1.2 × 0.6 m² commercial flexible modules have surpassed 18% efficiency.

In July, Renshine Solar introduced turnkey services for perovskite manufacturing (see China Solar PV News Snippets).

China’s Ministry of Finance backs Golden Solar restructuring

Heterojunction module maker Golden Solar has signed a Restructuring Financial Investment Agreement with Cinda Asset Management. As a financial investor, Cinda will inject RMB 11.25 million ($1.57 million) to subscribe for 1.5 million shares transferred from the company’s capital reserve at RMB 7.5 ($1.05) per share. Cinda is controlled by China’s Ministry of Finance, and the investment will be executed through a co-benefit debt-to-equity swap. The company aims to complete the restructuring plan by December 31, 2025.

In April 2025, the Shenzhen Stock Exchange issued multiple delisting and other risk warnings against Golden Solar. Last month, Golden Solar signed restructuring financial investment agreements with 16 institutional investors, receiving nearly RMB 1.42 billion ($197.18 million) in cash for its shares (see China Solar PV News Snippets).

Fujian seeks feedback on renewable power tariff reform

The Fujian Provincial Development and Reform Commission is soliciting public comments on its reform proposal for renewable power grid tariffs. According to the draft, starting January 1, 2026, all centralized and distributed wind and solar projects in the province will participate in market trading, with prices formed competitively.

The plan also includes a ‘renewable sustainable development settlement mechanism’, where existing projects (commissioned before June 2025) will adopt differential settlement based on the coal benchmark price of RMB 0.3932/kWh ($0.055/kWh), while new projects will determine tariffs via competitive bidding, with terms varying by project type. The document specifies that retail electricity prices for residential and agricultural users will not be affected by the reform.

Earlier this week, Guangdong province rolled out its market-based reform plan for renewable power pricing (see China Solar PV News Snippets).

Energy China subsidiary’s highway PV project breaks ground in Anhui

Gezhouba Group Transportation Investment (CGGC), a subsidiary of energy and power developer Energy China, has commenced construction of a highway transport-energy integration project on the Hexiang Expressway in Anhui Province. It is touted as the first nationwide project to achieve ‘synchronous design, construction, and commissioning’ for a full-road PV integration. The project aims to install 8.524 MW of PV capacity, generating around 8.48 million kWh annually. This will reduce CO₂ emissions by 4,170 tons and save 2,586 tons of standard coal annually, providing clean electricity for roadside infrastructure and vehicles. The project adopts an innovative ‘tunnel-entrance PV corridor’ model, which integrates PV modules into tunnel terrain, ensuring traffic safety while utilizing idle space for power generation.
