At its core is a **unique back-contact shingled cell technology**, where all electrical connections sit on the rear of the cell - this eliminates shading losses caused by front-side wiring and allows more active cell area to be packed into each panel. The panels feature **bifacial energy production**, so reflected light from the surrounding surface translates into a real boost in energy yield from the same roof or ground footprint. The series stands out for its **high resistance to micro-cracks, soiling, wind, hail, and extreme heat**, ensuring stable performance even in harsh climates and helping lower the levelized cost of energy (LCOE) over the system's lifetime. Commercial investors will also value the **market's lowest power degradation rate** and strong output under partial shading conditions. The entire line is backed by a **40-year warranty** covering product, power, and service, making Origin a solution built for businesses seeking predictable, long-term returns from their PV installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EN_SunPower_Origin_Datasheet_SPR-BE54-HD_485505W-9dd857525a32.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Jinko Solar JKM510T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm510t-48hl6m-db) | 510 W | Cooler, lighter, +0.8 pp | | [Jinko Solar JKM505T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm505t-48hl6m-db) | 505 W | Cooler, lighter, +0.6 pp | | [Jinko Solar JKM500T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm500t-48hl6m-db) | 500 W | Cooler, lighter, +0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, -10 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -10 W, lighter, -10 yr warranty | | [Jinko Solar JKM495T-48HL6M-DB](https://comparepv.com/panel/jinko-solar-jkm495t-48hl6m-db) | 495 W | -10 W, cooler, lighter | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, -10 yr warranty | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Lighter, -10 yr warranty | | [Maxeon SPR-P7-435-BLK](https://comparepv.com/panel/maxeon-spr-p7-435-blk) | 435 W | -70 W, -3.3 pp, -10 yr warranty | | [Maxeon SPR-P7-440-BLK](https://comparepv.com/panel/maxeon-spr-p7-440-blk) | 440 W | -65 W, -3.0 pp, -10 yr warranty | | [Maxeon SPR-P7-445-BLK](https://comparepv.com/panel/maxeon-spr-p7-445-blk) | 445 W | -60 W, -2.8 pp, -10 yr warranty | | [Maxeon SPR-P7-450-BLK](https://comparepv.com/panel/maxeon-spr-p7-450-blk) | 450 W | -55 W, -2.5 pp, -10 yr warranty | | [Maxeon SPR-P7-455-BLK](https://comparepv.com/panel/maxeon-spr-p7-455-blk) | 455 W | -50 W, -2.3 pp, -10 yr warranty | | [Maxeon SPR-P7-460-BLK](https://comparepv.com/panel/maxeon-spr-p7-460-blk) | 460 W | -45 W, -2.0 pp, -10 yr warranty | | [Maxeon SPR-BE54-HD485](https://comparepv.com/panel/maxeon-spr-be54-hd485) | 485 W | -20 W, -0.9 pp | | [Maxeon SPR-BE54-HD490](https://comparepv.com/panel/maxeon-spr-be54-hd490) | 490 W | -15 W, -0.7 pp | --- Source: https://comparepv.com/panel/maxeon-spr-be54-hd505 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
