Enel launches 680 W n-type heterojunction solar panel

Enel Green Power has unveiled its new heterojunction bifacial solar panel, meant for utility-scale PV projects. The panel is based on a G12 format, n-type solar cell with a power conversion efficiency of 24.6 per cent. It reportedly has a thickness of 150 µm at present, but the company’s roadmap has set a target of 120 µm by the end of 2025. With power outputs ranging from 640 W to 680 W and average efficiencies varying from 22.6 per cent to 22.9 per cent, the new panel is available in nine different configurations. The open-circuit voltage ranges between 43.3 V and 44.2 V, and the short-circuit current ranges between 18.9 A and 19.8 A.

The solar module weighs 36 kg and has dimensions of 2,172 mm x 1,303 mm x 35 mm across all configurations. The system’s maximum voltage is 1,500 V, and its bifaciality factor can go up to 95 per cent. With an operational temperature coefficient of -0.24 per cent per °Celsius, the panel can be used in temperatures between -40 °Celsius and 85 °Celsius. It also has a junction box with an IP68 certification and an anodised aluminium frame, and is enclosed by a 2 mm anti-reflective solar glass. It comes with a 20-year product guarantee and a 30-year linear power output guarantee.
