This makes the modules well-suited for high-humidity environments, coastal installations, and agro-PV applications where backsheet-based modules are prone to accelerated delamination. - **Bifacial design: measurable rear-side yield gain** - Bifacial PERC cells capture light reflected from the ground, delivering a real-world energy gain of 5-25% depending on ground albedo (light gravel/white roofing membrane: ~15-25%; grass: ~5-10%). On ground-mount and flat-roof installations with a reflective surface, the bifacial gain is significant at no additional BoS cost. - **30-year linear power warranty** - Jinko covers this series with a 30-year linear power warranty - exceeding many PERC contemporaries limited to 25 years. The guaranteed maximum annual degradation is 0.55%, corresponding to ~84% of nameplate power remaining after 30 years. - **Jinko Solar: #1 BNEF Bankability 2024** - JinkoSolar ranked #1 in Bloomberg NEF's 2024 PV Module Bankability Survey - the only manufacturer to achieve a 100% bankability score among 66 assessed companies, and Tier-1 for the 10th consecutive year. Bankable status means lenders accept these modules without additional credit enhancements, directly reducing project LCOE. - **Efficiency 20.71-21.29%: top of segment** - Peak module efficiency of 21.29% is essentially on par with direct PERC peers from the same era: Goldi Solar GS10-B144-TF (21.3%), IBC Solar 182M Half Cell (21.28%), S-Energy SL65-72BGJ (21.3%). The series does not concede power density to comparable competition. ## Cons - **Discontinued since 2023** - Jinko Solar ended production of this series in 2023. New module supply is limited to remaining warehouse stock, and warranty claim support (replacements, service) may become increasingly difficult over time. For installations designed for a 25-30 year lifespan, this represents material supply-chain risk compared to actively produced series such as the Tiger Neo (N-type). - **P-type PERC: higher degradation than N-type TOPCon** - P-type PERC cells degrade at 0.45-0.55% per year with a first-year LID of 1-3%, while N-type TOPCon modules degrade at 0.30-0.40%/year with LID ≈ 0.2-0.5%. After 25 years, PERC retains roughly 84-86% of rated power versus 88-92% for TOPCon - a 4-6 percentage-point gap that compounds into meaningfully lower cumulative energy yield over a full project lifetime. ## About this series The Jinko Solar JS-PERC Bifacial (Dual Glass) 535-550W series is designed to maximize energy yield in situations where every square meter and long-term stability are crucial. A key advantage is the **glass-glass construction**, which provides better protection for the laminate against moisture, UV radiation, and temperature fluctuations - making these modules a good choice even for installations exposed to harsher environmental conditions. The use of **monocrystalline PERC p-type bifacial cells** allows not only the use of direct light, but also reflected light from the ground, which provides additional yield in ground-mounted, flat roof, and other installations where a bright, reflective environment can be created. In practice, this series solves the problem of reduced production in less ideal conditions thanks to **excellent performance in diffuse light** and higher resistance to degradation factors. This is a proposal for investors who expect **higher production from the same surface area** and greater durability than in typical modules with a film on the back. ## Notable figures - Efficiency of 20.9% matches the \*\*PERC 500-550W\*\* median - Power density of 209.0 W/m² matches the \*\*PERC 500-550W\*\* median - At -0.34%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - Weight of 32.0 kg is 3.7 kg above \*\*PERC 500-550W\*\* median (28.3 kg) - verify structural support - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### Is the Jinko Solar JS-PERC Bifacial (Dual Glass) 535-550W series still available for purchase? This series has been discontinued. Individual units may still be found in distributor stock, but the product line is no longer actively manufactured. If you are planning a larger installation, confirm availability with your supplier or consider a current Jinko Solar series that comes with full warranty and service support. ### What warranty does the Jinko Solar JS-PERC Bifacial Dual Glass 535-550W carry? Jinko Solar provides a 15-year product warranty covering material defects and workmanship, along with a 30-year linear power output warranty. After 30 years, modules are guaranteed to retain at least 80% of their rated power. Maximum annual degradation is 0.45%, which is competitive for this product class. ### Does bifacial PERC technology actually deliver more energy - how much extra yield can I expect? Yes, bifacial cells capture light reflected from the ground or surrounding surfaces. In ground-mounted systems or on flat roofs, rear-side gain typically adds 5-15% over a monofacial panel. The actual gain depends on the albedo of the surface beneath the array - light gravel, concrete, and snow-covered ground deliver the best results. ### Why is the glass-glass construction in the 535-550W series better than a standard backsheet panel? A rear glass layer instead of a polymer backsheet dramatically reduces moisture ingress into the laminate, extending module lifespan. The dual glass design also offers superior UV and mechanical resistance. This matters most in high-humidity, coastal, or industrially polluted environments where backsheet degradation tends to accelerate over time. ### Do the Jinko Solar JS-PERC Bifacial 535-550W panels perform well in winter and under overcast conditions? Yes. Monocrystalline PERC cells have a favorable power temperature coefficient of approximately -0.35%/°C, meaning they lose less output on cold days compared to older cell technologies. The modules are rated for operating temperatures from -40°C to +85°C. Under diffuse light, PERC technology maintains relatively strong efficiency due to rear-surface passivation. ### Is the 535-550W series suitable for ground-mounted systems and larger solar farms? Yes, bifacial 72-cell modules rated up to 550W are frequently used in commercial and utility-scale ground-mounted PV installations. High per-panel wattage reduces module count and BoS (balance of system) costs. Certified wind load resistance of 2,400 Pa and snow load of 5,400 Pa make them suitable for demanding climate conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JS-PERC-BIFACIAL-535-550W-6c4c71875894.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.8 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.6 pp | | [Jinko Solar JKM525M-72HL4-TV](https://comparepv.com/panel/jinko-solar-jkm525m-72hl4-tv) | 525 W | -15 W, lighter, -0.5 pp | | [Jinko Solar JS182MHC144-525](https://comparepv.com/panel/jinko-solar-js182mhc144-525) | 525 W | Lighter, -0.6 pp, -5 yr warranty | | [Jinko Solar JKM530M-72HL4-TV](https://comparepv.com/panel/jinko-solar-jkm530m-72hl4-tv) | 530 W | Hotter, lighter, -0.3 pp | | [Jinko Solar JS182MHC144-530](https://comparepv.com/panel/jinko-solar-js182mhc144-530) | 530 W | Lighter, -0.4 pp, -5 yr warranty | | [Jinko Solar JKM535M-72HL4-(V)-F3-EN](https://comparepv.com/panel/jinko-solar-jkm535m-72hl4-v-f3-en) | 535 W | Hotter, lighter, -5 yr warranty | | [Jinko Solar JKM535M-72HL4-BDVP](https://comparepv.com/panel/jinko-solar-jkm535m-72hl4-bdvp) | 535 W | Hotter, heavier | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +100 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/jinko-solar-js540m144bdg 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.
