Alpha Pure-R is no longer the flagship in REC's HJT lineup, though it remains in active production and fully warranty-supported. - **Full bifacial gain depends on mounting conditions** - Realized bifacial energy gain depends on ground albedo and mounting height — on typical pitched roofs with limited rear clearance, the additional rear-side yield may be marginal relative to the price premium of the technology. ## About this series The REC Alpha Pure-R series redefines performance standards through the use of advanced **heterojunction (HJT) cells**, which combine the benefits of crystalline and thin-film silicon. The innovative, gapless cell layout allows for maximum active surface density, translating into more power generated from every square meter of the roof. This is an ideal solution for homeowners with limited installation space who are looking for maximum energy yields. These panels effectively eliminate the problem of performance drops in high temperatures and partial shading, which is possible thanks to the unique division of the module into four independent sections. REC Alpha Pure-R also features a breakthrough **completely lead-free construction**, making it one of the most eco-friendly premium products on the PV market. The product is dedicated to demanding prosumer installations, where elegant **All-Black aesthetics** must harmonize with uncompromising mechanical durability. It stands out from the competition with an optimized version of **Twin Design technology**, which ensures stable system operation even in difficult weather conditions. Choosing this series is an investment in energy security and the highest component operating standards for at least 25 years of use, guaranteeing the lowest rate of power degradation over time. ## Notable figures - Efficiency of 22.3% matches the \*\*HJT 400-450W\*\* median - Power density of 222.3 W/m² matches the \*\*HJT 400-450W\*\* median - Temperature coefficient of -0.24%/°C matches the \*\*HJT 400-450W\*\* median - 21.5 kg weight - 1.5 kg lighter than \*\*HJT 400-450W\*\* median (23.0 kg), reducing installation effort - Ranked #5100 out of 14005 panels for efficiency in the database ## Questions ### What are the product and power output warranties for the REC Alpha Pure-R panels? Under the REC ProTrust program — available when the system is installed by an REC Certified Solar Professional — you receive a 25-year product warranty and a 25-year power output warranty. After 25 years of operation the panel must retain at least 92% of its nameplate power, with a maximum warranted annual degradation of 0.25%, one of the lowest figures in the premium PV segment. ### Do REC Alpha Pure-R panels lose significant power on hot summer days? No. The HJT cell technology used in the REC Alpha Pure-R delivers a temperature coefficient of just -0.24%/°C for PMAX. By comparison, conventional PERC panels typically range from -0.34% to -0.40%/°C. In real-world terms this translates into noticeably higher energy yield during summer heat waves and better annual production figures in warm climates. ### How does the REC Alpha Pure-R handle partial shading from a chimney or TV antenna? The REC Alpha Pure-R module is internally split into four independent electrical sections, so shade falling on one portion of the panel limits losses only to that section — the remaining area continues operating at full power. Combined with the Twin Design architecture and the high efficiency of HJT cells, this series is especially well suited for rooftops with complex geometry or obstructions. ### How does the HJT technology in the REC Alpha Pure-R differ from mainstream PERC, and is the premium worth it? HJT cells stack a crystalline silicon wafer between thin amorphous silicon layers, achieving up to 22.3% module efficiency in the 430 Wp variant, along with a better temperature coefficient and lower long-term degradation than PERC. You get more energy from the same roof area over the full system lifetime. The premium is most justified when available mounting space is limited or an All-Black aesthetic is required. ### The REC Alpha Pure-R is bifacial — does that make sense on a pitched residential roof? Yes, though bifacial gains on a pitched roof are smaller than on a ground-mount system. The panel captures light reflected from the roofing surface or underlayment membrane, potentially adding a few percent of additional annual yield. The benefit is greatest on light-colored surfaces or where a structural gap exists between the panel and the roof. On a standard tile roof the bifacial design still improves the energy balance, though it is not the primary reason to choose this series. ### Is REC a reliable manufacturer, and who backs the 25-year warranty? REC Group is a Norwegian company with over 25 years of PV industry experience and is consistently ranked among Tier 1 manufacturers by Bloomberg NEF. The Alpha Pure-R panels are produced at ISO-certified facilities in Singapore. Tier 1 status reflects the financial strength needed to honor warranty obligations across a 25-year operational horizon, making REC a low-risk choice for long-term energy investments. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DS_Alpha_Pure-R_IEC_EN_AUCEC_101125_0-daf50a60886a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, +1.8 pp, +5 yr warranty | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, +1.8 pp, +5 yr warranty | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, +1.7 pp, +5 yr warranty | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, hotter, +1.7 pp | | [REC REC400AA PURE-R](https://comparepv.com/panel/rec-rec400aa-pure-r) | 400 W | -30 W, -1.6 pp | | [REC REC410AA PURE-R](https://comparepv.com/panel/rec-rec410aa-pure-r) | 410 W | -20 W, -1.1 pp | | [REC REC420AA PURE-R](https://comparepv.com/panel/rec-rec420aa-pure-r) | 420 W | -10 W, -0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +80 W, +2.7 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +65 W, +2.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +75 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +60 W, +2.2 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +70 W, +2.2 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +70 W, +2.2 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/rec-rec430aa-pure-r-1 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
