In a new weekly update for pv magazine, Solcast, a DNV company, reports that in January most of East Asia experienced normal to above-average solar irradiance, with southeastern China seeing surges due to reduced clouds and low aerosol levels under lingering La Niña effects. In contrast, the Philippines faced below-average irradiance from early Tropical Storm Nokaen, while other regional cities like Seoul, Tokyo, and Taipei recorded modest gains.

Sungrow is introducing its large-scale energy storage system, PowerTitan 3.0, to Europe, featuring grid-forming capability, next-generation battery cells, DC coupling for co-located solar projects, and streamlined commissioning to accelerate deployment.

The South Korean giant said its new EHS All-in-One provides air heating and cooling, floor heating, and hot water from a single outdoor unit. It can supply hot water up to 65 C in below-zero weather.

The Dutch start-up, founded by former Tesla leaders, is taking a novel approach to sodium-ion battery technology, optimizing it for integration with solar power plants. Its technology is set to be deployed for the first time in a Dutch solar-plus-storage project later this year.

Envision Energy has launched a fully integrated energy storage solution combining hardware, software, and market-facing AI to optimize performance, safety, and trading. Its “Physical AI” platform embeds intelligence across cells, systems, and operations, enabling predictive maintenance and real-time market participation.

China installed a record 315 GW (AC) of new solar capacity in 2025, lifting cumulative installed PV capacity to 1.2 TW and pushing non-fossil power sources past thermal generation for the first time.

Sodium‑ion batteries are emerging as a safer, lower-cost alternative to lithium‑ion, with a recent international study highlighting their competitiveness in stationary energy storage. The research shows that ongoing investment and supply-chain development could enable broader adoption within the next decade.

Pilot long-duration energy storage (LDES) project uses low viscosity, denser-than-water fluid. RheEnergise is panning for future projects in 10 MW to 100 MW range, with six to 20 hours of storage capacity.

Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and reliability across varying solar conditions. Simulations in multiple Chinese cities show the system can significantly cut electricity use and cooling costs, making it promising for sustainable building cooling and future commercial scaling.

SunWiz market data ranks the manufacturer as the top energy storage supplier in Australia, Ireland, and South Africa.
