Scientists in China have analyzed the impact of soiling of PV module performance and have found that tilt angle has the greatest impact, followed by irradiance intensity and dust deposition density.

Scientists in China have simulated a system that combines liquid-based direct air capture with diabatic compressed air energy storage, for the benefit of both processes. Exploring its economic feasibility, they found the system could achieve a levelized cost of energy of $0.53/kWh and a levelized cost of CO2 captured from air of $259/tCO2.

Researchers had placed a cotton sheet on the back of a PV module, which was then made wet and cooled. On the front side, water was pumped water from a pipe in a way that kept the panel both cool and clean. Their experimental setup showed superior results compared to reference cooling technologies.

The battery features four MPPTs and can take up to 2,600 W of PV input. It also has an AC nominal output power of 800 W.

Atess Power has released a 1,500 kW battery for commercial and industrial (C&I) solar, with up to eight units operating in parallel for 12 MW of capacity. The Chinese inverter manufacturer also offers 1,000 kW and 1,200 kW models.

The industry will reach the 1 TWh demand milestone in 2024, with China producing more than three-quarters of the batteries sold globally. The concentration of the production chain in the country has led to a fall in costs and a possible technological shift with the focus on LFP batteries. Cooperation between countries can be strategic to diversify the battery production chain and create sustained demand, assesses the International Energy Agency.

China installed 277.57 GW of solar in 2024, up 28.3% from 2023 and bringing total capacity to 887 GW., according to the China Photovoltaic Industry Association (CPIA).

The Chinese manufacturer has collaborated with Japan’s Daidohant on the new product. It reportedly suppresses deformation with a special bar attached to the back of the solar module.

Scientists in China have analyzed the performance of a system linking a solar-air source heat pump heating system to sand-based thermal storage floor and have found it can maitain an average indoor temperature of 18.8 C, even when outdoor temperatures range from −18.4 C to 12.3 C.

The Chinese manufacturer said that its new glass-backsheet Windproof module utilizes a zinc-aluminum-magnesium surface alloy technology and a high-strength steel substrate. It features a power conversion efficiency of up to 23.03%.
