After 30 years, the module retains ≥87.4% of rated power — a clear advantage over PERC technology, where annual degradation reaches 0.55%/year and typical retention after 25 years is around 84.8%. - **Favorable temperature coefficient** - The Pmax temperature coefficient of –0.30%/°C outperforms standard PERC modules (–0.35 to –0.40%/°C). In climates where module temperatures regularly exceed 55–65°C during summer, this difference translates to measurably higher seasonal energy yield. - **80% bifaciality + glass-glass construction** - An 80% bifaciality factor (±5%) enables 10–25% additional rear-side energy harvest depending on ground albedo. The glass-glass encapsulation delivers superior mechanical strength, PID resistance, and UV durability, with compliance confirmed by IEC 61215:2021 and IEC 61730:2016 certifications. - **Up to 23% efficiency – top of segment** - The 460W variants reach 23% module efficiency, matching direct peers Risen RSM96-11-440-460BNDG (23%) and SunKean SKT440~460M12-96D4 (23.02%), while significantly outperforming Zonergy ZPM MH3-72 (21.16%). High efficiency reduces the roof area required for a given system output. - **BNEF Tier-1 bankable manufacturer** - Jolywood appears on the BNEF Tier-1 list (Q2 2026), confirming bankability for commercially financed projects. Founded in 2008, with annual production capacity of approximately 10 GW, the manufacturer offers a sound counterparty risk profile for both residential and commercial installations backed by project finance. ## Cons - **12-year product warranty** - The materials and workmanship warranty is 12 years, whereas Jolywood's own updated datasheet (version V202502) already lists 25 years. If the supplied series is sourced from an older contract batch (12-year terms), it falls short of the market's leading offers — e.g., SunPower and select JA Solar lines provide 25-year workmanship coverage. Buyers should verify the warranty document at point of purchase. ## About this series The Jolywood JW-HD108N-R3 Black Series is designed for high energy output and a consistent, modern appearance. The use of **N-type TOPCon monocrystalline cells** translates to more stable performance over time and reduced susceptibility to typical efficiency losses, which investors planning long-term operation will appreciate. The **bifacial** design allows capturing additional energy from the rear side as well - particularly where the surface reflects light (bright roof, gravel, snow) or during vertical installation. A clear distinguishing feature is the **glass-glass construction**, which enhances resistance to moisture, temperature fluctuations, and mechanical stress, ensuring the panels perform well in challenging environmental conditions. The series also features the **"full black" aesthetic**, making it a popular choice for residential rooftops, but it is also suitable for commercial installations, carports, and projects requiring durability and reliable returns. In practice, its unique combination of TOPCon technology, bifacial design, and glass-glass construction offers an option focused on both appearance and longevity. ## Notable figures - Efficiency of 23.0% matches the \*\*TOPCon 450-500W\*\* median - 230.2 W/m² power density - 5.0 W/m² more than \*\*TOPCon 450-500W\*\* median (225.2 W/m²), more power per roof area - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 450-500W\*\* median - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - In the top 14% for efficiency among all TOPCon panels ## Questions ### What warranty does the Jolywood JW-HD108N-R3 Black Series come with? The JW-HD108N-R3 Black Series carries a 12-year product warranty and a 30-year linear power output warranty. Jolywood guarantees at least 93.4% of rated power after 15 years and 87.4% after 30 years of operation. This extended performance warranty provides predictable return on investment across the full intended service life of the system. ### How do TOPCon cells in the Jolywood JW-HD108N-R3 compare to standard PERC cells? The N-type TOPCon cells used in the JW-HD108N-R3 have a lower temperature coefficient of approximately -0.28%/°C versus roughly -0.35%/°C for conventional PERC, meaning smaller power losses on hot days. TOPCon is also inherently resistant to light-induced degradation (LID) and exhibits a slower annual degradation rate, delivering higher cumulative energy yield over the decades-long system lifetime. ### Does the bifacial design of the Jolywood JW-HD108N-R3 actually increase energy production on a residential rooftop? The bifacial gain is most meaningful where the rear surface receives reflected irradiance — light-colored roofing membranes, gravel ballast, snow cover, or vertical mounting orientations. On a dark asphalt shingle roof the effect is minimal. For a typical pitched installation on a lighter substrate, a realistic additional yield of 3–8% per year compared to a monofacial module of the same rated power is achievable. ### Does the glass-glass construction of the JW-HD108N-R3 make rooftop installation more difficult? Glass-glass JW-HD108N-R3 modules weigh approximately 21 kg, slightly heavier than glass-backsheet alternatives. This requires the correct number of mounting clamp points per the manufacturer's specification and appropriately rated racking hardware. For an experienced installation crew this is straightforward, while the benefit is significantly improved resistance to moisture ingress, snow load cycling, and thermal stress — all of which extend the practical service life of the array. ### What applications beyond pitched rooftops suit the Jolywood JW-HD108N-R3 Black Series? The all-black aesthetic on both module faces makes the Black Series a popular choice for carports, solar fencing, and BIPV facade applications where appearance matters. The bifacial capability and mechanical durability of the glass-glass structure also make it practical for ground-mounted systems and agri-PV projects. With peak power up to 460 Wp, the series is equally well suited to commercial rooftop installations where maximizing output per unit area is a priority. ### How does the Jolywood JW-HD108N-R3 perform in cold climates and low-irradiance conditions? N-type TOPCon technology demonstrates better low-light and diffuse-irradiance response than PERC, which is relevant in northern European climates with frequent overcast days. The low temperature coefficient (-0.28%/°C) allows the module to operate more efficiently than P-type alternatives during cold, sunny winter days. The glass-glass build also handles repeated freeze-thaw cycles and heavy snow loads particularly well. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/da9f327cba26f2e8-c78c05ad44dc.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, lighter, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, lighter, +1.5 pp | | [Jolywood JW-HT108N-R3-430W](https://comparepv.com/panel/jolywood-jw-ht108n-r3-430w) | 430 W | -30 W, lighter, -1.5 pp | | [Jolywood JW-HT108N-R3 435W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-435w) | 435 W | -25 W, lighter, -1.2 pp | | [Jolywood JW-HT108N-R3 440W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-440w) | 440 W | -20 W, lighter, -1.0 pp | --- Source: https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-460 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
