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.
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.
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.
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%.
Chinese PV Industry Brief: Longi raises wafer prices
Furthermore, Solar manufacturer JinkoSolar was listed on Wednesday on the Shanghai Stock Exchange (SSE) and Zhonghuan Semiconductor said it expects a 286% growth in profits for 2021.
Russia deployed 233 MW of solar in 2021

Solar-plus-storage autonomous power generator from Spain
Developed in Spain, the Arca system integrates solar panels, power electronics, and energy storage. Arca Lite has a rated power of 490 Wp, and Arca Plus of 980 Wp.
Novel methodology to identify solar-suitable roofs
Swedish scientists developed a three-step method that integrates techniques used for the automatic extraction of buildings along with their underlying roof faces, as well as the identification of utilizable rooftop areas for solar arrays. The novel methodology is claimed to avoid overestimating actual potential of buildings for PV deployment.
