The new algorithm monitors the inverter subsystems and sends alarms when maximum and minimum values are reached. It analyses data and categorises variables according to historic values.

China’s Sinopec has switched on the world’s largest solar-to-hydrogen project in Xinjiang, while India has unveiled a new plan to incentivize green hydrogen and electrolyzer production.

Portuguese startup Solarud has developed a way to eliminate soiling around the frames of PV panels with low inclination slopes. The device drains water that would otherwise stay stagnant on the surface of modules.

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.

The device was designed by scientists in Portugal to optimise light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.

The stunning low tariff is a third world record in five weeks. Solar prices continue to tumble and with a Saudi auction concluding tomorrow, the Iberian benchmark could be short-lived. The official result of the Portuguese tender will be announced August 10.
