Description
Jolywood Niwa Black 500 W Bifacial Glass-Glass Solar Panel
The Jolywood Niwa Black JW-HD108N-R2-500 combines 500 W rated front-side output with n-type J-TOPCon cell technology and a bifacial glass-glass construction. Its black anodised aluminium frame and ultra-thin busbars provide a clean appearance, while the transparent glass-glass design allows the rear side to capture reflected sunlight.
Designed for photovoltaic installations where electrical compatibility, mounting requirements and site conditions have been checked, this module offers 22.5% efficiency under Standard Test Conditions.
Key features
-
500 W rated output: Front-side nominal power measured under Standard Test Conditions.
-
N-type J-TOPCon technology: Designed for low light-induced degradation and reliable long-term performance.
-
Bifacial generation: The rear side can contribute additional output when reflected light reaches it.
-
Glass-glass construction: 2.0 mm heat-strengthened glass on both the front and rear.
-
Black frame: A neat finish for visually coordinated PV installations.
-
Power temperature coefficient of −0.280%/°C: Output decreases as cell temperature rises; this coefficient describes that change.
-
IP68 junction box: Equipped with three bypass diodes.
-
Manufacturer warranty: The datasheet specifies a 25-year product material and workmanship warranty and a 30-year linear performance warranty, subject to the manufacturer’s warranty terms.

Electrical ratings are measured at STC: irradiance 1000 W/m², cell temperature 25°C and AM1.5. Actual output depends on sunlight, temperature, orientation, shading and installation conditions. Bifaciality is a rear-to-front rating ratio, not a guaranteed 80% increase in energy yield.
Manufacturer performance warranty
The datasheet states a maximum first-year degradation of 1.0%, followed by 0.40% annual degradation, with a warranted output level of 87.4% at year 30. Warranty coverage and claims are governed by the manufacturer’s applicable terms.
