WHES has released a new commercial and industrial (C&I) energy storage system using a 509 kWh battery with power output options from 62.5 kW to 250 kW, and a maximum efficiency of 98.5%.

An international research team has tested a hybrid control technique combining adapted perturb and observe (APO) with model-predictive control to address complex partial shading in solar arrays. The method, validated through simulation and physical experiments, reportedly outperforms existing approaches.

Researchers in China have investigated how market segment spillover effects materialized in the Chinese PV supply chain from 2017 to 2024, and have identified a series of hedging strategies that could help manufacturers reduce risks. Their analysis showed these effects are triggered based on an ‘’upstream-driven, downstream-responsive’’ contagion pattern.

The Chinese company stated that its new H02 product line is available in either single-phase or three-phase configurations. It comes with a different number of 5.12 kWh batteries.

Zhejiang Bangjie Holding Group has canceled its planned CNY 8 billion ($1.10 billion) solar manufacturing project in Jiangshan, while Arctech Solar has secured a 2.3 GW tracker deal in Saudi Arabia.

Scientists in China have simulated an advanced adiabatic compressed air energy storage, to which they added an elastic airbag with a heavy load situated above it. The energy, exergy, and economic analysis of the system showed that, due to the constant weight of the heavy load, the airbag’s pressure level remains unaltered during operation.

China Railway Construction Corp.’s IT unit has named 10 preliminary winners for its 2025 solar module framework procurement. The 3 GW contract covers n-type monocrystalline bifacial tunnel oxide passivated contact (TOPCon) modules, with delivery required within 170 days of signing.

Researchers have combined the theory of planned behavior, the technology acceptance model, and diffusion of innovations theory to investigate rooftop solar adoption in China. From a 1,200-person survey, they found that subjective norms and social influence from peers and community had a surprisingly more substantial effect than personal attitudes or perceived ease of use.

China is set to break new ground in its energy transition, with 2025 renewable capacity additions projected to exceed 500 GW, driven by surging solar and wind deployment, according to a new report from the State Grid Energy Research Institute.

China’s top industry officials have vowed to curb low-price competition and excess capacity in the solar sector, as authorities begin implementing measures aimed at stabilizing supply chains and rebalancing the market.
