Perovskite PV manufacturer, GCL Perovskite, has completed an end-to-end production run on its GW-scale perovskite module manufacturing line, covering the entire process from raw-material intake to the production of large-area modules. The company said commercial module deliveries are gradually increasing as its focus shifts to production stabilization and yield ramp-up. Current priorities include improving equipment stability during continuous operation, overall line yield, and material utilization while reducing unit manufacturing costs. GCL Perovskite added that its 2 m² single-junction perovskite module has received third-party certification of IEC 61215, while its perovskite-crystalline silicon tandem module has received both IEC 61215 and IEC 61730 certifications. In another development last year, GCL Perovskite led space PV module standard drafting (see China Solar PV News Snippets)
In a technology upgrade, JinkoSolar plans to invest RMB1.792 billion in its Yuanhua base in Haining, Zhejiang province. The project will retire older equipment including texturing machines and tabber-stringers, and introduce advanced wet-processing and patterning equipment, and deploy digital systems including MES, SAP and AI-based tools. According to publicly disclosed environmental impact assessment materials, the project will retire the site’s existing 6 GW crystalline silicon cells and 6 GW modules, while retaining the cell R&D functions. Following the upgrade, the facility plans to have an annual production capacity of 2.7 GW of high-efficiency “new-structure” cells and 4 GW modules. The publicly disclosed EIA materials do not explicitly identify the technology that will be used for the new cells.
Battery manufacturer, CBAK Energy, has disclosed internal test results for its 32140 NH-7Ah full-tab sodium-ion cell and outlined a conditional long-term plan for 12 GWh of annual sodium-ion battery production capacity. The planned lines will be designed to support both sodium-ion and lithium-ion cell production. The company said its NFPP cell reached 90% charge within 15 minutes, while capacity retention remained above 95% during continuous discharge at 15C. At -40°C, the cell retained 87.68% of its discharge capacity relative to its 25°C baseline. Based on internal cycle-life testing and trend analysis, CBAK Energy projects at least 10,000 life cycles under specified protocols. Customer testing of samples is underway in residential and portable energy storage systems, and two and three electric wheelers, while additional evaluations cover backup power and other applications.
EVE Energy has signed a strategic cooperation agreement with China Railway Beijing Engineering Group Co., Ltd., a subsidiary of China Railway Group, with the two companies agreeing on at least 5 GWh of energy storage project over the next three years. The partnership will focus on new energy projects, energy storage applications and coordination in infrastructure development, supported by a dedicated working mechanism. China Railway Beijing Engineering Group is active in infrastructure, power, solar and EPC projects, while EVE Energy supplies energy storage cells and integrated storage systems. The companies plan to combine their engineering and storage equipment capabilities to advance related projects.
Energy China has launched its 2026 centralized procurement for PV modules, with an estimated volume of 15 GWp across 6 packages, covering EPC and self-invested projects. This year’s procurement is 2 GW smaller than its 17 GW procurement of 2025 with 8 packages. Covering TOPCon, HJT and BC module technologies, the bids are due by October 9, 2026. Here are more details:
For the two TOPCon packages, bidders must have at least 2.5 GWp of cumulative sales over the previous three years from individual contracts of 10 MWp or more.
Package 4 additionally requires at least four individual TOPCon contracts of 100 MWp or more.
The HJT packages require at least 150 MWp of cumulative sales over the same period, while the BC packages require at least 1.5 GWp of cumulative module sales across all technology types.
