Renac Power unveils high-voltage residential battery

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.

Sharp launches 540 W bifacial solar module

Sharp’s new IEC 61215 and IEC 61730-certified-certified panel features 144 half-cells based on M10 wafers and a 10-busbar design. Its operating temperature coefficient is -0.349% per degree Celsius and its power tolerance reaches up to 5%.

MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Bromine-based flow batteries for renewables storage

Bromine-based flow batteries have the potential for high energy density in renewable energy storage. Their commercial adoption, however, remains challenging due to the cathode materials used for their construction. New research from China seeks to shed light on how to overcome these hurdles.

France defines standards for agrivoltaics

France’s environmental agency Ademe has released a set of new guidelines that clearly define “agrivoltaics.”

Long-duration storage solution based on saltwater

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilises three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.

Growatt unveils solar rechargeable portable power station

Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Myanmar’s steeplechase towards renewable energy

Myanmar’s government has announced a plan to increase conventional and renewable energy generation to address electricity shortages. Reports from Burmese exiles, however, detail increasing issues for the construction of large scale solar projects tendered prior to the military coup in February 2021 and Chinese inverter manufacturer Sungrow said the project it secured in the country’s first tender has been canceled.
