The panel measures 1,894 mm x 1,096 mm x 30 mm, weighs in at 22.5 kg, and has a temperature coefficient of -0.34% per C.

Researchers in China have fabricated a heterojunction solar cell with a 244.63 cm2 Czochralski n-c-Si wafer. They used light soaking to improve the dark conductance of the hydrogenated amorphous silicon films.

Researchers in Singapore have developed a new technique in which polycrystalline silicon is pulverized into powder and pelletized into ingots. The process relies on spark plasma sintering to dope the silicon with germanium and phosphorus.

Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modeling assumed a typical commercial building in Los Angeles.

US scientists have developed a way to remove snow and ice from solar panels at a much faster rate than conventional approaches. It is based on a glass coating on a film with high optical transparency and superhydrophobicity.

Indian scientists have developed a system under which a pumped-hydro facility stores grid electricity during off-peak hours by pumping water to an upper reservoir. During peak hours, the system feeds the load, rather than taking power from the grid.

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’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.

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’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%.
