Multi-level fin heat sinks for solar module cooling
Developed by Malaysian scientists, the proposed multi-level aluminum fin heat sinks (MLFHS) were found able to reduce the module operating temperature by up to 8.45 degrees Celsius and increase power yield by up to 10.75%. The system cost was estimated at $0.60/W.
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.
Portuguese solar plants – tendered and merchant – remain in limbo
One of the first items in the in-tray of the country’s new Socialist Party government must be to unblock Portugal’s seemingly huge appetite for PPA-backed merchant solar sites and to deliver the PV projects which were tendered by the authorities, to global acclaim, in 2019 and 2020.
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.
Botswana-Namibia green hydrogen project expands to 5GW
The raised ambition of an already huge renewables-powered hydrogen project in the Southern African nations vividly demonstrates the hydrogen and clean energy potential of a continent which accounted for just 0.5% of the world’s new solar capacity last year, according to trade body AFSIA’s annual report.
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%.
