Jolywood 380 Full Black Bifacial Photovoltaic Panel

The Jolywood JW-HD120N photovoltaic panel in the 380 W version is a bifacial N-type mono module in an aesthetic, "all black" design, intended for roof and ground-mounted installations. It provides high efficiency while maintaining power in low light conditions and reduced light degradation (zero LID) thanks to the J-TOPCon 2.0 technology.

Manufacturer: Jolywood (Taizhou) Solar Technology Co., Ltd. Jolywood is a supplier of N-type bifacial modules with full production automation, holding quality and environmental certifications (including IEC61215, IEC61730, ISO9001, ISO14001, ISO45001) and a position in the BNEF Tier One ranking.
