Chinese power transformer manufacturer TBEA introduced a grid-forming string power conversion system (PCS) for utility-scale storage, renewable energy base projects, and weak-grid applications. The TE435/392K-HV-BL high-power converter focuses on improving power density and grid support. According to TBEA, its fully integrated liquid-cooling design increases volumetric power density by 78% and gravimetric power density by 32% […]

Sungrow says energy storage systems overtook PV inverters as its largest business segment in 2025, as the company posted double-digit revenue and profit growth.

TCL Zhonghuan has agreed to take majority control of Chinese solar manufacturer DAS Solar, a producer of advanced n-type modules based on tunnel oxide passivated contact (TOPCon) and back-contact (BC) technologies.

A team from Nankai University and the Shanghai Institute of Space Power-Sources has developed a hydrofluorocarbon electrolyte enabling lithium-metal cells to operate at temperatures as low as -70 C.

China-based solar manufacturer Longi is shifting from a multi-vendor system design to a unified solar-plus-storage architecture built around in-house technologies.

JinkoSolar has formally terminated its 4 GW Hai Ha solar cell project in Vietnam, citing US antidumping duties that undermined its export economics. The company will maintain other Vietnamese operations while shifting focus to localized supply chains and Asia-Pacific and Middle East markets.

Tongwei is partnering with GS-Solar and Golden Solar to develop a large-scale manufacturing facility for hybrid heterojunction back-contact (HBC) solar cells that combine heterojunction passivation, tunneling oxide and polysilicon structures used in TOPCon designs, and the grid-free front-side architecture typical of back-contact technologies.

China’s National Energy Administration (NEA) says newly installed solar capacity reached 32.48 GW in the first two months of 2026, while the China Nonferrous Metals Industry Association (CNMIA) says polysilicon prices fell by as much as 7.95% in the latest week.

The US International Trade Commission (ITC) has opened a Section 337 investigation into tunnel oxide passivated contact (TOPCon) solar cells, modules, panels, and related products following a complaint by First Solar, naming 47 entities across 11 countries as respondents.

Hongyuan Green Energy (Hysolar) says it plans to take control of Wuxi Suntech Solar Power through a court-led restructuring that transfers core assets into a new entity while isolating legacy debt.
