Strong in heat, no clear weak spot
The Jolywood JW-HD96N (Black Series) are bifacial glass-glass modules designed to operate reliably in both rooftop and ground-mounted installations. The use of n-type TOPCon cells translates to higher energy yield predictability over time and reduced degradation typically observed in the early stages of operation. Thanks to the ZERO LID feature, energy production does not decline due to light-induced degradation, a key advantage for long-term investments.
This is an excellent solution where performance in variable conditions is crucial - the series features better response to low light conditions, supporting energy generation in the morning, evening, and on cloudy days. Additionally, its low temperature coefficient helps mitigate power losses during summer, when modules tend to heat up.
The Black Series is designed for investors seeking to combine aesthetics (full black or black frame) with premium performance parameters - suitable for residential rooftops, commercial installations, and challenging environments, such as humid, dusty, or windy locations. The difference compared to many competitive series lies in the focus on the reliability of TOPCon technology and broader applications, including BIPV and vertical mounting.

Signals from the data
Residential, commercial, BIPV and hot-climate.
Top 11% of the TOPCon 450-500 W segment, against a median of -0.290.
N-type cells eliminate light-induced degradation (LID/LeTID) inherent to older PERC technology. In practice this means no initial power step-loss in the first weeks of operation, improving yield predictability over the full investment horizon.
Jolywood guarantees at least 87.4% of nominal power after 30 years — both the term and the threshold exceed the standard offered by many comparable TOPCon series (e.g., Recom Lynx and Sunlike Solar offer similar peak power but shorter or equal warranty periods). Product warranty is 25 years.
A Pmax temperature coefficient of -0.280%/°C compares favorably to typical PERC modules (-0.34% to -0.36%/°C) and is competitive within the premium TOPCon segment. With a NMOT of 45±2°C, the series maintains stable output under peak summer conditions.
An ~80% bifaciality factor in a 2.0 mm/2.0 mm double-glass build enables meaningful rear-side energy capture in ground-mounted and high-albedo installations. The glass-glass structure also improves mechanical durability and extends real-world module lifetime.
Jolywood appears on the BNEF Tier 1 list in Q2 2026 (one of 42 global manufacturers), confirming bankability for internationally financed projects. The company has been operating since 2008 with an annual production capacity of approximately 10 GW.
The glass-glass construction (2.0 mm/2.0 mm) results in a module weight of 24.6 kg, roughly 10–15% heavier than a comparable glass-backsheet module (~21–22 kg). On older rooftops this may require an additional structural load assessment before installation.
- At 22.8% efficiency, this panel is on par with typical TOPCon 450-500W modules
- Power density of 227.7 W/m² matches the TOPCon 450-500W median
- Temperature coefficient of -0.28%/°C matches the TOPCon 450-500W median
- Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface
- #2714 for efficiency, #1309 for temperature performance out of 14005 panels

Measured curves published by Jolywood in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 455 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
