The manufacturer holds Tier-1 BNEF status (confirmed Q3 2024), minimizing bankability risk for project financing. ## Cons - **Weight 33.3 kg – heavier than glass-backsheet** - The dual-glass construction results in a module weight of 33.3 kg, approximately 20–25% more than comparable glass-backsheet modules of similar wattage (typically 26–29 kg). Rooftop installations may require reinforced racking and substructure, increasing BoS costs and complicating at-height logistics. - **30-year power retention lower than LONGi Hi-MO 7** - Jolywood guarantees ≥87.4% power after 30 years (degradation ~0.40%/yr), while the LONGi Hi-MO 7 LR8-66HGD declares a 0.35%/yr degradation rate, implying approximately 88.85% retention at year 30. The 1.45 pp gap translates to roughly 145 Wp of real-world advantage for the competitor at the end of the warranty period on a 10 kWp system. ## About this series Jolywood JW Plus Series JW-HD132N-R2 photovoltaic panels are an advanced solution based on innovative **N-type TOPCon** technology, which provides significantly higher efficiency compared to traditional cells.

The JW Plus JW-HD132N-R2 includes a 12-year product warranty covering materials and workmanship. The linear power warranty extends to 30 years, with Jolywood guaranteeing at least 87.4% of nominal output after that period. First-year degradation is capped at 1%, followed by no more than 0.4% per year — one of the most competitive performance guarantees available in the market. ### How does the TOPCon technology in the Jolywood JW-HD132N-R2 compare to PERC cells? The N-type TOPCon cells in the JW-HD132N-R2 deliver module efficiency above 22%, clearly outperforming standard PERC modules (approx. 20–21%). The tunnel oxide passivation layer minimizes carrier recombination, boosting output from the same roof area. Critically, N-type TOPCon cells are free from LID (light-induced degradation), ensuring stable power output throughout the module's entire service life — a significant advantage over PERC technology. ### Do the bifacial Jolywood JW-HD132N-R2 panels actually generate more energy than standard monofacial modules? Yes. The bifacial glass-glass design of the JW-HD132N-R2 captures reflected irradiance through the rear side, delivering 10–30% additional energy in typical installation environments. Gains are highest on ground-mounted systems or light-colored surfaces such as gravel, concrete, or snow. Even rooftop installations with light-colored underlays show a measurable increase in annual energy yield. ### How do the Jolywood JW Plus JW-HD132N-R2 panels perform during hot summer days? The temperature coefficient of Pmax is just -0.28%/°C, significantly better than typical PERC modules (-0.34 to -0.37%/°C). When cell temperature reaches 65°C on a hot August afternoon, the JW-HD132N-R2 loses proportionally less power than older technologies. This low temperature coefficient, combined with N-type TOPCon cells, results in higher real-world energy yield during peak summer hours. ### Is the glass-glass construction of the Jolywood JW-HD132N-R2 more durable than a standard backsheet module? Yes. The dual-glass construction withstands front-side mechanical loads of 5,400 Pa (roughly 550 kg/m²) and rear-side loads of 2,400 Pa, and passes hail impact tests with 35 mm diameter balls. Unlike PVF or PET backsheets, tempered glass does not degrade from UV exposure or moisture ingress, significantly extending the module's service life — often well beyond 30 years of operation. ### Are the 625 Wp Jolywood JW Plus JW-HD132N-R2 panels suitable for a typical residential pitched roof? The JW-HD132N-R2 measures 2382×1134×30 mm and weighs approximately 33.3 kg. Installation on a pitched roof is fully achievable using standard racking systems compatible with a 30 mm frame depth. At least two installers are recommended given the module size and weight. The high 625 Wp unit output reduces the total panel count needed, which is a key advantage when available roof area is limited. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JOLYWOOD-JW-HD132N-f2ad49771e0f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +1.9 pp | | [Jolywood JW-HD132N-R2 595W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-595w-1) | 595 W | -15 W, cooler, -0.6 pp | | [Jolywood JW-HD132N-R2-600W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-600w) | 600 W | -10 W, cooler, -0.4 pp | | [Jolywood JW-HD132N-R2-605W](https://comparepv.com/panel/jolywood-taizhou-solar-technology-co-ltd-jw-hd132n-r2-605w) | 605 W | Cooler | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +2.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +2.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +60 W, lighter, +2.2 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +60 W, lighter, +2.2 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +60 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/jolywood-jw-hd132n-610 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.
