Jolywood JW-HD108N2-R2 500W Solar Panel

Highly efficient bifacial solar module from the NIWA Black series, created using modern n-type cells and featuring a durable Bifacial Dual-Glass design. This model combines a rated power of 500 W, an efficiency of 22.5%, and an all-black design with thin busbars.

The bifacial design allows solar radiation to be utilized from both the front and rear of the panel. This makes the module suitable for various types of solar power systems, including rooftop and ground-mounted systems, vertical mounting, and BIPV, as well as operation in high humidity, snow, and sand.

The use of n-type cells ensures no light-induced LID degradation and promotes stable generation over a long service life. The power temperature coefficient is -0.280%/°C, allowing the panel to operate more efficiently at elevated temperatures. The manufacturer also notes improved performance in low light conditions and high resistance to hot spots.

The module consists of 108 photovoltaic cells, features double-glazed, 2 mm-thick heat-strengthened glass, and an anodized aluminum alloy frame. The junction box has an IP68 protection rating of and is equipped with three diodes. The maximum system voltage is 1500 VDC, and the mechanical load reaches 5400 Pa on the front side and 2400 Pa on the back side.

First-year degradation is stated at no more than 1%, and subsequent annual degradation is 0.40%.
