The Pmax temperature coefficient of -0.280%/°C translates to measurably higher summer energy yield compared to standard PERC modules (-0.35%/°C), improving real-world annual kWh output. - **Up to 23.6% efficiency — top of segment** - The 525 Wp variant reaches 23.6% module efficiency, matching the Jinko Tiger Neo 54HL4M-BDV (23.61%) and outperforming the VSUN N-132MH-BB (22.11%). The 6-variant lineup spanning 500–525 Wp provides flexibility for roof-area-constrained system design. - **30-year linear power warranty (≥87.4%)** - Jolywood guarantees at least 87.4% of rated power after 30 years. Most Tier-1 peers (Trina, JA Solar) offer 25-year warranties degrading to approximately 84.8%, making this series more favorable for LCOE calculations over long investment horizons. - **Bifacial dual-glass — up to +25% rear-side gain** - The bifacial design with 2.0/2.0 mm dual-glass construction captures light reflected from the ground surface. The manufacturer rates bifacial gain at up to +25% under favorable conditions (high-albedo surface, ground-mount or flat roof with adequate clearance). Dual-glass also improves PID resistance and moisture durability in coastal or industrial environments. - **BNEF Tier-1 Q2 2026 + Kiwa PVEL Top Performer (4 consecutive years)** - Jolywood is listed on the BNEF Tier-1 bankable manufacturer list for Q2 2026, confirming eligibility for independent commercial bank financing on utility-scale projects. Four consecutive Kiwa PVEL Top Performer Module Scorecard recognitions provide third-party evidence of consistent manufacturing quality and below-average field degradation risk. ## Cons - **Limited brand presence in Poland** - Jolywood has a single official distributor in Poland (Łódź), while Jinko Solar, Longi, and Trina Solar maintain extensive multi-tier distribution and service networks in the country. For commercial installations with SLA requirements, longer RMA response times represent a real operational risk. - **27.3 kg module weight — structural constraint** - The dual-glass construction results in a module weight of 27.3 kg (1960×1134×30 mm), approximately 25–30% heavier than comparable single-glass / backsheet modules (~20–22 kg). Large rooftop installations on older or industrial buildings may require additional structural load calculations, adding engineering cost to the BoS budget. ## About this series The Jolywood JW-HD108N-R2 Black Series are full-black modules designed for maximum energy yield where both performance and roof aesthetics matter. Using N-type TOPCon cells helps reduce typical power losses over time - a tangible benefit for investors seeking sustained high output over long years, not just during the first season. The bifacial construction harnesses reflected light, supporting higher energy yields particularly when installed on light surfaces, flat roofs, and ground-mounted systems. In practice, this series addresses two common challenges: limited installation space and production drops under demanding conditions. Thanks to double glazing, the modules are ready for operation in high-humidity environments and heavy-duty applications, while the full-black appearance makes them easy to integrate with modern buildings. This is an excellent choice for premium homes, businesses, and installations demanding high reliability and refined visual appeal. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 500-550W\*\* modules - At 225.0 W/m² power density, roof space requirements are typical for \*\*TOPCon 500-550W\*\* panels - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 30% for efficiency among all TOPCon panels ## Questions ### What is N-type TOPCon technology in the Jolywood JW-HD108N-R2 series and why does it matter? The N-type TOPCon cells in the JW-HD108N-R2 deliver lower annual degradation than conventional P-type PERC cells. The module achieves efficiency of approximately 22.5–23.6% and a low temperature coefficient of Pmax at just -0.28%/°C, reducing output losses on hot days. In practice, this means measurably more kilowatt-hours per year throughout the system's lifetime compared to previous-generation technology. ### What warranty does the Jolywood JW-HD108N-R2 Black Series carry? The JW-HD108N-R2 series comes with a 25-year product warranty and a 30-year linear power warranty. After 30 years the manufacturer guarantees at least 87.4% of the module's rated output. This is one of the longest warranty coverages available on the market, directly reducing investment risk and improving LCOE calculations for long-term energy projects. ### What additional energy yield does the bifacial design of the JW-HD108N-R2 provide? Thanks to its bifacial glass-glass construction, the JW-HD108N-R2 harvests light reflected from the ground, rooftop membrane, or surrounding surfaces. The manufacturer rates the bifacial gain at up to +25% compared to a monofacial module. The best results are achieved on flat roofs with white TPO or PVC membranes, light-colored gravel ballast, and ground-mounted or tracking systems. ### Are the full-black Jolywood JW-HD108N-R2 panels suitable for a pitched roof with dark tiles? Yes, the JW-HD108N-R2 series is compatible with standard rail-based racking systems designed for pitched roofs. The all-black aesthetic — black frame, black cells, black glass — blends seamlessly with dark ceramic or bitumen tiles, making it a preferred choice for premium residential builds. At 1960×1134 mm and approximately 27.3 kg, the modules require a roof structure rated for the corresponding static and dynamic loads. ### How do Jolywood JW-HD108N-R2 modules perform in winter and harsh weather conditions? The glass-glass construction provides strong resistance to moisture ingress, rapid thermal cycling, and snow loads. The modules operate across a temperature range of -40°C to +85°C and feature an IP68-rated junction box. The low temperature coefficient of Pmax (-0.28%/°C) also limits output losses during summer heat waves compared to standard P-type PERC panels. ### Is Jolywood a reliable manufacturer and is the JW-HD108N-R2 Black Series still available for purchase? Jolywood holds Tier 1 manufacturer status according to BNEF, confirming full bankability and established financial stability. The JW-HD108N-R2 Black Series remains in active commercial availability and is distributed through authorized partners across Europe. We recommend verifying stock for the specific wattage variant (up to 525 Wp) with your local distributor before placing an order. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/jw-hd108n-r2-500-525w-fb-85b055aa195e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.0 pp | | [Jolywood JW-HT120N-R3-485](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht120n-r3-485) | 485 W | -15 W, lighter, -0.6 pp | | [Jolywood JW-HT120N-R3-490](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht120n-r3-490) | 490 W | -10 W, lighter, -0.3 pp | | [Jolywood JW-HD120N-R3-495](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd120n-r3-495) | 495 W | Very close match | | [Jolywood JW-HD120N-R3-500](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd120n-r3-500) | 500 W | Very close match | | [Jolywood JW-HD108N-R2-505](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505) | 505 W | Very close match | | [Jolywood JW-HT120N-R3-505](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht120n-r3-505) | 505 W | Lighter, +0.3 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +60 W, lighter, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +55 W, lighter, +2.1 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +50 W, lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +40 W, lighter, +1.9 pp | --- Source: https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-500 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.
