The series clearly outperforms Leapton LP182 (22.36%), placing it in the top tier of high-power 132-cell TOPCon modules. - **Low degradation: N-type TOPCon** - N-type cells deliver ≤1% first-year degradation and ≤0.40%/year linear annual degradation — versus ≤2% and ≤0.55%/year for typical PERC modules. This results in a guaranteed ≥87.4% of rated power after 30 years, while standard PERC modules typically guarantee only ~84.8% through year 25. - **Temperature coefficient of −0.30%/°C** - A Pmax temperature coefficient of −0.30%/°C is 0.05 percentage points better than standard PERC modules (−0.35%/°C). At Central European summer module temperatures of 55–75°C, this meaningfully increases daily energy yield without any changes to system design. - **Bifacial glass-glass construction** - Bifacial design enables up to ~30% additional backside power generation (BiFi gain) on top of the nameplate rating on high-albedo ground surfaces. The glass-glass build raises mechanical resistance to 5,400 Pa (snow load) and 2,400 Pa (wind load), exceeding IEC 61215 minimum thresholds — a strong fit for ground-mount farms and flat commercial rooftops. - **30-year linear power warranty + Tier-1 bankability** - Jolywood guarantees ≥87.4% of rated power after 30 years (0.40%/year linear), one of the longest warranty coverages in the TOPCon segment. Tier-1 bankable status (BNEF Q1 2026) enables project financing by independent commercial banks without additional module insurance requirements. ## Cons - **Module weight ~33.3 kg (glass-glass)** - The glass-glass construction results in a module weight of ~33.3 kg — roughly 15–20% heavier than comparable glass-backsheet variants (27–30 kg). Rooftop retrofits may require structural load verification, and the added weight increases installation labor, making it a relevant BoS cost factor at scale on existing buildings. - **Smaller production scale vs. segment leaders** - Jolywood's annual shipment volumes are significantly lower than Longi (~85 GW/year) or Jinko Solar (~95 GW/year), which can limit supply flexibility and renegotiation leverage for procurement contracts above 50 MWp. Large-scale EPC projects should verify manufacturing allocation well in advance of scheduled delivery windows. ## About this series The Jolywood JW Plus (JW-HD132N-R2 595-625W) series are modules based on **N-type TOPCon cells**, designed for high energy production in real-world conditions - even when the installation does not have ideal sunlight. Thanks to the **bifacial glass-glass construction**, the panel can also utilize reflected light from the ground, which helps increase yield on PV farms, flat roofs, and ground-mounted structures with a light-colored base. In practice, this series addresses typical challenges of large projects: yield fluctuations on cloudy days, faster power degradation, and the risk of performance drops in harsh working environments. The applied N-type solutions support **low degradation and stable operation over time**, while the glass-glass structure improves mechanical and operational durability. The JW Plus is a good choice for investors and contractors looking to maximize production from the same surface area, prioritizing **good performance in low light conditions**, and seeking a module that is clearly more advanced technologically than standard P-type panels. ## Notable figures - At 23.1% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - At 231.4 W/m² power density, this panel generates 3.7 W/m² more per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 600-650W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 11% for efficiency among all TOPCon panels ## Questions ### What efficiency and power output do the Jolywood JW Plus JW-HD132N-R2 panels achieve? The JW Plus JW-HD132N-R2 series delivers 595 to 625 Wp with module efficiency ranging from 22.0% to 23.1%. These figures are noticeably above standard P-type PERC panels. The high efficiency is achieved through N-type TOPCon cell technology and a 132-cell layout in a compact 2382×1134×30 mm frame. ### Are the bifacial JW Plus panels worth it for a utility-scale PV farm or flat roof? Yes. The glass-glass bifacial construction captures reflected irradiance from the ground surface, which can boost energy yield by 10–30% compared to a monofacial equivalent when a light-colored surface (gravel, white membrane, concrete) is used. The JW Plus series is especially well-suited for ground-mount systems, flat commercial rooftops, and carport canopies where the rear side is exposed. ### How fast does the power output of Jolywood JW Plus panels degrade over the years? The linear performance warranty caps first-year degradation at 1%, followed by no more than 0.4% per year thereafter. After 30 years, Jolywood guarantees at least 87.4% of the nameplate power. This is one of the lowest degradation rates commercially available, driven by the N-type TOPCon architecture's inherent resistance to LID and PID effects. ### What warranties are included with the Jolywood JW Plus JW-HD132N-R2 solar panels? Jolywood provides a 12-year product warranty covering manufacturing defects and materials, plus a 30-year linear power warranty with a defined degradation schedule. As a Tier 1 manufacturer, Jolywood's financial stability supports the practical enforceability of these warranties. The glass-glass construction further protects against moisture ingress, improving long-term durability beyond what a glass-backsheet module offers. ### Do the JW Plus JW-HD132N-R2 panels perform well in overcast conditions and low temperatures? Yes. N-type TOPCon cells outperform P-type PERC in diffuse light, meaning the module starts generating energy earlier in the morning and later in the evening. The low temperature coefficient of -0.28%/°C per degree Celsius limits power losses during hot summer days, while cooler ambient temperatures in winter actually improve efficiency, partially compensating for reduced solar irradiance. ### How does the TOPCon technology in the Jolywood JW Plus differ from standard P-type PERC panels? TOPCon (Tunnel Oxide Passivated Contact) cells used in the JW Plus series are built on an N-type silicon substrate free of boron, making them virtually immune to the LID (Light-Induced Degradation) effect that affects P-type PERC modules. Superior surface passivation, lower leakage current, and higher cell efficiency translate into greater annual energy output from the same roof area compared to a conventional PERC module. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ecb9691926b382c5-88294bda50ec.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +25 W, lighter, +2.1 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +1.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, lighter, +1.7 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, lighter, +1.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +1.7 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +45 W, cooler, +1.7 pp | | [Jolywood JW-HD132N-R2 595W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-595w-1) | 595 W | -30 W, -1.1 pp | | [Jolywood JW-HD132N-R2-600W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-600w) | 600 W | -25 W, -0.9 pp | | [Jolywood JW-HD132N-R2-605W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-605w) | 605 W | -20 W, -0.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +55 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +75 W, cooler, +1.9 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +70 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-625w 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.
