Dual-component controller for three-phase solar inverters can reduce overshoot to less than 0.33%
An international research team has conceived a dual-component controller for three-phase inverters that can reportedly achieve faster settling times, reduced overshoot and more stable current tracking compared to conventional controllers.
Scatec signs PPA for large-scale solar-plus-storage project in Egypt
Norway’s Scatec Asa has signed a 25-year power purchase agreement (PPA) with Egypt Aluminium for a 1.1 GW solar plant with 100 MW/200 MWh of battery energy storage. The agreement has been billed as Egypt’s first utility-scale PPA with an industrial offtaker.
Experimental system cools PV panels while keeping them clean
Researchers had placed a cotton sheet on the back of a PV module, which was then made wet and cooled. On the front side, water was pumped water from a pipe in a way that kept the panel both cool and clean. Their experimental setup showed superior results compared to reference cooling technologies.
