The Chinese manufacturer has upgraded its commercial application battery with a dissipative balancing technology that, it is claimed, will make the storage system suitable for different load conditions. Each battery module is sold with a capacity ranging from 100 to 200Ah and a storage capacity of 7.68kWh.

Italian and Iranian researchers have developed the new “deposition via an antisolvent-soaked applicator” technique, which they describe as an easily scalable process to produce uniform, pinhole-free perovskite films. They tested the process on a 6.7%-efficient solar cell based on a polyethylene terephthalate substrate, raising its power conversion efficiency by 82%.

Solar manufacturer RenewSys has expanded its encapsulant capacity to 3GW with the addition of a new line at its facility in Bengaluru, India. The company aims to eventually expand its encapsulant capacity to 11 GW.

Ratings agency Crisil estimates India will have 38-43GW of annual solar module manufacturing capacity by the end of March 2025. Production capacity will be driven by strong domestic demand, favorable government policy, raised module conversion efficiency, and price competitiveness, according to the ratings agency.

Scientists in Singapore have developed a cell that could be used to power vehicles and boats, among other applications. The tandem device purportedly retains 90% initial efficiency after 500 hours of maximum power point tracking under continuous one sun illumination.

Scientists in China analyzed defective solar cells based on Czochralski (Cz) silicon wafers and found Swirl defects may be responsible for an efficiency drop of up to 4.7%. According to them, the presence of Swirl defects could be mitigated by applying a heat treatment at a temperature above 1,050 degrees Celsius in a clean environment before the manufacturing of the solar cells.

With five public entities having committed RMB1.25 billion into a project to produce copper, indium, gallium, selenide solar modules five years ago, the joint venture has been abandoned at an estimated impairment cost of RMB1.42 billion.

Growatt’s new AXE LV battery covers a wide range of capacities, from 5kWh to 400kWh, and can support off-grid systems with power outputs of 3kW to 30kW.

Through the procurement exercise, the power utility is seeking proposals to deploy around 600MW of capacity that will have to start providing power in February 2026, and another 250MW to begin commercial operations in February 2027.

The National Energy Administration (NEA) reported this week that the newly installed PV capacity for the Chinese market reached around 53 GW last year. Of this capacity, around 29 GW comes from distributed generation projects. The country’s cumulative installed power reached 306 GW at the end of December.
