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%.

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.
