US microgrid project using vanadium redox flow battery
SDG&E and Sumitomo Electric complete a pilot microgrid project in California that successfully powered utility customers solely with energy stored in a flow battery.
Belectric builds another floating solar park in Israel
The project is the fourth floating solar array that Belectric develops and builds in Israel.
Chile’s first fast-charging station for EVs
The recharging station will operate 24 hours a day and in a flexible format, which will allow fleets of electric buses, last-mile distribution vehicles, trucks, taxis and private electric cars to be supplied through fast charging points.
The panel and the city
US researchers have investigated how rooftop PV systems may affect air and building temperature in urban environments and, conversely, how the urban heat island (UHI) effect may have a negative impact on PV system performance. Their work considered urban air temperature, urban air pollution, the partial shading of the PV system, soiling, building heating and cooling loads, and outdoor shade.
Peru wants to tender 2 GW of renewables this year
Through two different auctions, the Peruvian government expects to mobilize investments of around $2 billion.
Germany deployed 5.26 GW of solar in 2021
The country saw around 421 MW of new PV capacity come online in December alone. Its cumulative solar power reached 56.3 GW.
FuturaSun launches rooftop solar module with 390-410 W output
The new product measures 1754x1098x30 mm and weighs in at 21 kg. It features a temperature coefficient of -0.35% per degree Celsius and a power conversion efficiency of up to 21.29%.
Vanadium redox flow battery to control extreme power ramps in rooftop PV
Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.
India’s NTPC tenders 500 MW/3,000 MWh of energy storage projects
Global bids are invited to develop a cumulative 500 MW of energy storage system facilities on a “build-own-operate” basis anywhere in India. The proposed plants can be set up ranging in sizes from 100 MW to 500 MW, with the capacity to store at least six hours of electricity — for example, a 500 MW project with a minimum energy storage capacity of 3,000 MWh. Bidding closes on March 11.
Perovskite solar module with 18.45% efficiency via co-solvent dilution strategy
The module was fabricated with methylammonium lead iodide (MAPbI3) perovskite solar cells via low-cost spin coating. The panel also achieved an open-circuit voltage of 16.07 V, a short-circuit current of 69.52 mA, and a fill factor of 75.35%.
