France-based FHE Group has developed a 2.5 kWh storage device that can store electricity as heat during the day and release this heat at night to power a heat pump for space heating and hot water. According to the manufacturer, it can retain over 95% of its initial performance after 20,000 cycles.

Scientists in Italy designed the prototype as a microcavity enclosing a molecular dye known as Lumogen-F orange (LFO). The charging power of the device is described as super-extensive, meaning that it increases faster with battery size.

According to official statistics from grid operator TEIAS, the country’s cumulative PV capacity reached 7.81 GW at the end of December.

TOPCon solar cells are on their way to fully compete with PERC solar products, according to recent research from Germany’s Fraunhofer ISE. Efficiency gains for the TOPCon concept, however, are necessary to help it capture more market share, as production costs remain higher than those for PERC tech. A series of cost-driven strategies to make TOPCon modules advance were outlined in the study.

The provisional figure took the nation to a cumulative 215MW at the end of the year, according to new statistics provided by Norwegian solar industry organization the Solenergiklyngen.

Called the 1+X modular inverter, the new product can be deployed, by combining eight units, to reach a power of 8.8MW. It also features a DC/ESS interface for the connection of storage energy systems.

The energy giant acquired solar-konzept Italia Srl, which has a portfolio of solar projects at different stages of approval and development. The solar parks are planned to sell electricity to commercial and industrial customers.

SMA’s new hybrid inverter reaches a maximum efficiency of 98.2% and a maximum European efficiency of 97.5%. It is compatible with DC-coupled high-voltage lithium-ion batteries from leading suppliers, according to the manufacturer.

The Sun Rock building is owned by Taiwan’s power utility Taipower. It was covered with 4,000 square meters of PV panels deployed by Dutch architectural firm MVRDV.

The south-oriented project has been under development since 2019 and is set to occupy a total surface of 10 hectares across two plots. It will provide power to the municipalities of Bunnik, Odijk, and Werkhoven
