Norwegian startup Over Easy Solar AS is launching a vertical PV system for rooftop applications at this year’s Smarter E in Munich, Germany.
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.
UK group develops liquid air energy storage tech
A UK consortium has developed the Prisma system, which stores thermal energy in liquid air form to provide onsite compressed air, via a latent energy cold storage tank filled with a phase-change material. It is expected to have a levelized cost of storage of GBP 114 ($143.10)/MWh.
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.
Mobile agrivoltaic system from the Netherlands
Created by a Dutch group of companies and research institutions, the mobile solar system may also be combined with an electrolyzer for hydrogen generation. Two prototypes are currently being tested by a farmer and a research institute in the Netherlands.
Growatt unveils solar rechargeable portable power station
Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.
New solar module cooling tech based on porous nanochannels
US scientists have utilized a nanochannels device to cool down the operating temperature of a commercial PV module and have found that the proposed technique is able to improve power yield by up to 32.8%. Spray droplets are dispersed over the nanochannels device in order to eliminate the need for a continuous supply of a coolant.
Zinc-ion battery for residential applications
Developed by Canadian start-up Salient Energy, the zinc-ion battery has a rated capacity of 60 Ah, a nominal voltage of 1.3 V, and a volumetric energy density of 100 Wh/L. The device measures 26cmx24cmx1.2cm and weighs in at 1.3 kg
Glass-integrated BIPV module from Japan
Japanese glass manufacturer AGC has developed a building-integrated PV (BIPV) panel for different building requirements. It can be installed on facades, canopies, and curtain walls where normal glass can be placed.
