New 29% efficient solar panel combines space-grade PV cells with concentrated glass cover
Solar Power World | February 19, 2019
Swiss company Insolight has reached 29% efficiency for its unique solar panel, as verified by the Solar Energy Institute of the Universidad Politecnica de Madrid (IES-UPM). Its patented optical system concentrates light onto an array of tiny space-grade multi-junction PV cells. Compared to traditional non-concentrated PV modules with efficiencies around 19%, Insolight’s pre-production module has been validated at 29% by IES-UPM, two years after the first lab prototype.
