Jetion presents heterojunction solar module series based on n-type G12 wafers
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.
Storing renewables with high-rise elevators
Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.
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.”
Photovoltaics vs. nuclear power on Mars
Solar might be more efficient than nuclear energy to supply power for a six-person extended mission to Mars that will involve a 480-day stay on the planet’s surface before returning to Earth, according to new US research.
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.
Malaysia’s water reservoir to host 150 MW floating solar plant
The floating facility will be built by Japan’s Shizen Energy and will sell power under unspecified conditions to local utility Syarikat Air Melaka Bhd (SAMB).
