The JW-HT108N matches the efficiency leaders in its power class. - **TOPCon N-type: low Pmax/°C, zero LID** - The temperature coefficient of power is –0.30%/°C, better than standard P-type PERC cells (–0.35% to –0.37%/°C). At a typical summer module temperature of 55 °C, this advantage translates to approximately 1.5–2 percentage points higher energy yield versus legacy PERC. N-type cells are inherently free from Light-Induced Degradation (LID). - **30-year linear power warranty ≥87.4% Pmax** - Jolywood guarantees ≤1% first-year degradation and ≤0.40%/year linear degradation, resulting in ≥87.4% of rated power after 30 years. This outperforms standard 25-year PERC warranties (typically flooring at ~84.8% Pmax) and matches leading TOPCon lines such as JA Solar JAM72S30 and LONGi Hi-MO 6. - **True all-black design with N-type technology** - The JW-HT108N combines a fully black aesthetic (black cells, black frame, black backsheet) with TOPCon N-type cells — unlike many all-black alternatives that rely on older PERC technology. The visual appeal is not achieved at the cost of performance; efficiency remains on par with white-framed equivalents in the same power class. - **BNEF Tier-1 bankable manufacturer since 2008** - Jolywood maintains Tier-1 status per BloombergNEF (confirmed 2025–2026), meaning bankability has been validated by at least six financial institutions in non-recourse project financing. Founded in 2008 with a specialization in N-type cells, the company's longevity reduces long-term warranty claim and technical support risk over a 20–30-year asset life. ## Cons - **12-year product warranty** - The product (materials and workmanship) warranty is 12 years, while leading Tier-1 manufacturers in the all-black TOPCon segment (e.g. JA Solar Deep Blue 4.0, Trina Vertex S+) standardly offer 15–25 years. The gap is relevant when assessing long-term risk in externally financed projects or when calculating TCO for commercial installations. ## About this series The Jolywood JW-HT108N (Black Series) are panels designed for maximally aesthetic installations without compromising on premium technology. What sets them apart is their **full-black design** - a uniform color scheme for the cells, frames, and rear layer, ensuring the modules blend seamlessly with modern roofs, especially in highly exposed installations. The application of **N-type cells in TOPCon technology** translates to more stable performance over time and better resistance to typical efficiency losses, which is crucial for long-term operation. They are also **monofacial modules**, making them an ideal choice for pitched and flat roofs on single-family homes and smaller commercial buildings, where predictable yield and a consistent appearance matter. This series resolves the compromise between aesthetics and profitability - offering **high efficiency** and a refined structure, distinguishing itself from many "black" panels that are primarily a visual gimmick. This is a proposition for investors who want their PV installation to be discreet, durable, and technologically advanced. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - 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 - Weight of 21.7 kg (2.3 kg below \*\*TOPCon 450-500W\*\* median of 24.0 kg) allows easier transport and roof mounting - In the top 19% for efficiency among all TOPCon panels ## Questions ### How does the Jolywood JW-HT108N Black Series differ from regular all-black solar panels? Most all-black panels are primarily a cosmetic choice — a black frame combined with standard cells and a white backsheet. The JW-HT108N Black Series delivers a truly uniform black aesthetic across cells, frame, and backsheet without sacrificing performance. Crucially, Jolywood uses N-type TOPCon cells with efficiency above 22%, rather than the lower-cost PERC technology found in many visually oriented all-black modules. ### What is TOPCon technology and why does it matter for the Jolywood JW-HT108N panels? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture that minimizes charge carrier recombination losses. In practice this means a better temperature coefficient (approx. -0.30%/°C), zero LID (Light Induced Degradation), and slower long-term power degradation. Compared to PERC, TOPCon panels retain significantly higher output after 25–30 years of operation, directly improving LCOE and return on investment. ### Are Jolywood JW-HT108N Black Series panels suitable for pitched residential rooftops? Yes, the JW-HT108N is a monofacial module designed with pitched-roof residential installations in mind. The all-black aesthetic integrates seamlessly with dark roof tiles or contemporary architecture where the array is highly visible. With output up to 460 Wp per panel, fewer modules are needed to meet a typical household's energy demand, reducing roof load and simplifying the overall BoS design. ### What warranty does the Jolywood JW-HT108N Black Series carry? Jolywood provides a 12-year product warranty covering material defects and workmanship, plus a 30-year linear power warranty. The power warranty limits annual degradation to approximately 0.4% after year one, guaranteeing at least 87.4% of nominal output at the end of year 30. As a Tier 1 manufacturer, Jolywood has the financial standing and track record to back these long-term commitments reliably. ### How do Jolywood JW-HT108N panels perform in hot weather and low-light conditions? The N-type TOPCon cells carry a temperature coefficient of approximately -0.30%/°C — better than typical PERC cells at -0.35%/°C — so output losses on hot summer rooftops are meaningfully lower. The technology also improves weak-light response, meaning the panels generate proportionally more energy on overcast days. Both advantages contribute to higher annual energy yield in temperate climates. ### Is the Jolywood JW-HT108N Black Series a bifacial module? No, the JW-HT108N Black Series is a monofacial module — it generates electricity from the front side only. The solid black backsheet is an aesthetic design choice, not a power-generating surface. If bifacial output is a priority, Jolywood offers separate glass-glass bifacial series such as the JW-HD108N, which captures reflected irradiance from the rear side as well. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/89bf81dd815deae2-46d0bee5e32e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, cooler, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, cooler, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Jolywood JW-HT108N-R3-430W](https://comparepv.com/panel/jolywood-jw-ht108n-r3-430w) | 430 W | -25 W, hotter, -1.3 pp | | [Jolywood JW-HT108N-R3 435W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-435w) | 435 W | -20 W, -1.0 pp | | [Jolywood JW-HT108N-R3 440W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-440w) | 440 W | -15 W, -0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-455w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
