Thanks to **N-type cells with hybrid passivation technology**, the module delivers exceptionally high conversion efficiency, squeezing more energy out of limited roof space - a key advantage in dense urban settings and on smaller roof areas. The signature **all-black panel with a busbar-free front** creates a smooth, uniform surface that blends seamlessly into the roofline, satisfying even the most demanding homeowners. The series also stands out for its **low power temperature coefficient**, meaning the module loses less output during hot weather and maintains stable productivity throughout the summer season. Low annual degradation combined with a robust design and encapsulation structure translates into **long-term, predictable system lifespan**, further reinforced by the manufacturer's **lifelong warranty support**. This is a solution for homeowners and businesses who expect not only high power output, but also premium aesthetics and peace of mind for decades of operation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JKM485-510T-48HL6M-DB-EN-e68d168e1c7a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Jinko Solar JKM510T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm510t-48hl6m-db) | 510 W | +20 W, +1.0 pp | | [Jinko Solar JKM505T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm505t-48hl6m-db) | 505 W | +15 W, +0.8 pp | | [Jinko Solar JKM500T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm500t-48hl6m-db) | 500 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +20 W, heavier, +0.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Hotter, lighter, +0.3 pp | | [Jinko Solar JKM495T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm495t-48hl6m-db) | 495 W | +0.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +15 W, heavier | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +15 W, hotter, heavier | | [Maxeon SPR-BE54-HD505](https://comparepv.com/panel/maxeon-spr-be54-hd505) | 505 W | +15 W, hotter, heavier | | [Jinko Solar JKM420N-54HL4R-BDV](https://comparepv.com/panel/jinko-solar-jkm420n-54hl4r-bdv) | 420 W | -70 W, hotter, -3.5 pp | | [Jinko Solar EU-JKM425-450N-54HL4R-BDB-G4 (425W class)](https://comparepv.com/panel/jinko-solar-eu-jkm425-450n-54hl4r-bdb-g4-425w-class) | 425 W | -65 W, hotter, -3.2 pp | | [Jinko Solar JKM430-455N-54HL4R-B-F8-EN (430W)](https://comparepv.com/panel/jinko-solar-co-ltd-jkm430-455n-54hl4r-b-f8-en-430w) | 430 W | -60 W, hotter, -3.0 pp | --- Source: https://comparepv.com/panel/jinko-solar-jkm490t-48hl6m-db Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
