JOLYWOOD JW-HD-156N-R0-640W Bifacial (N-type) Photovoltaic Panel

JOLYWOOD JW-HD-156N-R0-640W is a bifacial monocrystalline N-type module (TOPCon) in a dual-glass construction, designed for high-efficiency photovoltaic installations with increased energy production also from the rear side. The module offers a power tolerance of 0~+3% and high resistance to mechanical loads and environmental conditions.

Manufacturer: Jolywood (Taizhou) Solar Technology Co., Ltd. — a photovoltaic module manufacturer based in Taizhou, Jiangsu, China. The products meet quality and environmental management standards, including IEC61215, IEC61730, IEC61701, IEC62716, and ISO9001:2015, ISO14001:2015, and ISO45001:2018. The company develops n-TOPCon technology and employs processes that reduce the risk of micro-cracks and LID/LETID degradation.
