Huaneng Group has finished building a 300 MWh storage project in Changzhou, in China’s Jiangsu province. The state-owned company has already started operating the facility, which is situated in a salt cavern.

Chinese battery manufacturer BYD has launched an expanded portfolio of energy storage systems designed for the commercial and industrial solar markets. At The smarter E in Munich last month the company also provided a sneak peak at a new high-voltage storage system expected to be launched later this year.

Trina Solar will eventually start selling TOPCon and heterojunction products, even though it built its first large-scale TOPCon project four years ago. The company says it is now making progress on TOPCon module production, despite supply chain issues.

The World Intellectual Property Organisation says China accounted for 69% of the patents filed for transport-related fuel-cell tech in 2020, with road transport significantly dominating applications.

In other news, Zhonghuan Semiconductor announced it will begin selling 210 mm n-type wafers and the local government in Zhejiang Province said it wants to deploy another 12.4 GW of new PV by 2024.

Trina Storage’s new 2.1 MWh DC All-New Elementa solution is a modular LFP battery cabinet with a plug-in concept to connect multiple units. The company is ramping up battery manufacturing capacity to strengthen vertical integration, given supply chain risks throughout the world.

The largest product of the series is a solar module with an efficiency of up to 22.5% and a power output of up to 700 W. For all the panels of the series, the temperature coefficient is -0.26% per degree Celsius and the manufacturer offers a 12-year product guarantee and a 30-year power output guarantee.

The S5-EO1P(4-5)K-48 series off-grid PV inverter has an efficiency of 96.7% and supports parallel operation of up to 10 units, which allows for a system capacity of up to 50 kW. According to the manufacturer, the device is compatible with all top-tier brands of lithium-ion and lead-acid batteries.

In recent years, Longi has turned its attention to green hydrogen. Li Zhenguo, company founder and CEO, recently spoke to pv magazine about its strategic shift and how he believes that coupling this technology with solar PV will be the key to achieving carbon neutrality.

Renac Power’s new plug-and-play battery has a storage capacity of 3.74 kWh, but it can be enhanced in series with up to five batteries to 18.7 kWh. It has a nominal voltage of 96 V and a voltage range of 81 V to 108 V.
