Perovskite solar cell manufacturer Renshine Solar has announced that its mass-produced 30 × 40 cm large perovskite tandem module, with an aperture area > 900 cm², has achieved a conversion efficiency of 26.12%. This achievement, states the company, marks its entry into the industrialization of large-scale, high-throughput perovskite tandem technology. Renshine claims to have set 11 world records for perovskite solar efficiency, including a 30.1% efficiency for small-area (<1 cm²) perovskite tandem solar cells and 26.2% efficiency for small-scale tandem modules (~65 cm²).
Recently, in collaboration with Nanjing University, Renshine published its research on all-perovskite tandem solar cells in Nature Materials (see China Solar PV News Snippets).
Solar panel manufacturer Risen Energy has announced that it has won the bid to supply nearly 654 MW (DC) of solar modules for Phase II 500 MW (AC) of the Shen Energy Shule solar-storage integrated project. Risen will supply 653.59736 MW of n-type TOPCon bifacial double-glass solar modules (framed, 615 Wp or higher output) for this project. The contract is valued at RMB 4.52289 billion ($636.47 million), with a unit price of RMB 0.692/W ($0.095).
At the recent TaiyangNews annual flagship conference, Risen’s Jiajun Ye revealed that the company’s upcoming Hyper-ion Pro series 730 Wp+ HJT module is expected to enter mass production in Q1 2025 (see Risen Inches Toward 740W+ HJT Module).
Energy storage solutions provider Shijing Technology has projected a net loss of RMB 413 million ($56.97 million) to RMB 590 million ($81.38 million) in its earnings forecast for FY2024. This is a sharp decline from its reported net profit of RMB 217 million ($29.93 million) for FY2023.
The company attributed the losses to its 18 GW TOPCon cell manufacturing facility, which began ramping up production at the end of 2023 but faced low utilization rates and high fixed costs, resulting in significant losses. Additionally, declining prices across the solar PV supply chain squeezed margins, while delays in revenue recognition from some PV gas treatment and MEP system projects further impacted profitability.
Solar and decorative glass maker CSG Group has projected a net profit of RMB 209 million to RMB 310 million ($28.82 million to $42.74 million) for FY2024, representing an 81.28% to 87.38% year-on-year decrease. The company cited significant price declines in key PV supply chain products as the primary reason for reduced gross margins. Impairment provisions for related assets further pressured profitability.
China’s National Energy Administration (NEA) has released an update to its document titled ‘Distributed Solar PV Development and Construction Management Measures.’ To go into immediate effect, the document outlines development types, grid connection models, regulatory responsibilities, and construction standards for distributed solar PV projects, promoting an orderly and standardized industry. Key provisions include localized development, self-consumption priority, and differential grid connection requirements to encourage distributed PV participation in spot market trading. It also emphasizes user rights protection and regulates corporate development practices to safeguard farmers' interests.
The NEA recently reported that China added 120 GW of distributed solar PV capacity in 2024, representing 43% of the total new solar installations for the year (see China Solar PV News Snippets).
