This innovative approach eliminates the phenomenon of light-induced degradation and ensures excellent operating efficiency even in extremely high temperatures. A key advantage of this series is the **gapless cell layout**, which allows for maximum utilization of the module surface, generating significantly more energy from limited roof space than competing products. This series solves the dilemma between aesthetics and performance, offering an elegant look and the highest power in a compact size. Additionally, the completely lead-free construction makes them a **fully ecological and environmentally safe** product, confirming compliance with strict RoHS standards. Thanks to the unique, split panel architecture, these modules maintain high efficiency even in the case of partial shading, making them an ideal choice for complex roofs. The product is intended for conscious investors who expect **25-year ProTrust warranty protection** and reliability confirmed by rigorous durability tests. By choosing the REC Alpha Pure-R series, you are opting for the technological elite of photovoltaics, which guarantees the lowest power drop over time and maximum return on investment over decades of operation. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*HJT 400-450W\*\* modules - 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 - #5100 for efficiency, #13 for temperature performance out of 14005 panels ## Questions ### How does the HJT cell technology in REC Alpha Pure-R panels differ from conventional PERC cells? Heterojunction (HJT) cells stack monocrystalline silicon with thin amorphous silicon layers, fully eliminating light-induced degradation (LID). This yields a temperature coefficient of just -0.24%/°C, compared to roughly -0.35%/°C for typical PERC cells. In real-world terms, REC Alpha Pure-R panels retain significantly more output on hot summer days, making HJT a meaningful advantage over conventional module technologies. ### What is the peak power output and module efficiency of the REC Alpha Pure-R 430W panel? The top model in the series delivers 430 Wp at a module efficiency of 22.3%, ranking it among the highest-performing panels in the residential roof-mount format. The gapless cell layout fully utilizes the module's approximately 1.93 m² surface area, enabling greater energy harvest from a limited roof space compared to competing products with similar footprints. ### Are REC Alpha Pure-R panels bifacial, and does bifaciality matter on a typical pitched roof? Yes, the REC Alpha Pure-R is a bifacial module that captures albedo irradiance reflected from the surface beneath it. On a typical pitched roof with dark roofing tiles, the rear-side gain is minimal. However, installations above light-colored gravel, concrete, or snow can yield 5–20% additional output above rated front-side power. Bifacial gains are most significant in ground-mounted or flat-roof configurations. ### How well do REC Alpha Pure-R panels handle partial shading from chimneys or antennas? The module uses a half-cut cell layout with a split circuit architecture, so shading one section does not cause a disproportionate power loss across the entire module. HJT cells also inherently handle non-uniform irradiance better than standard PERC cells. This makes the REC Alpha Pure-R a solid choice for complex roofs with chimneys, dormers, antennas, or other obstructions that cause partial shading. ### What warranty does the REC Alpha Pure-R carry, and what is covered under the ProTrust program? The REC Alpha Pure-R comes with a 25-year product warranty and a 25-year power output warranty under the REC ProTrust program. The power warranty guarantees at least 92% of nominal output after 25 years of operation. ProTrust additionally covers labor costs for removal, replacement, and reinstallation of defective modules — a level of protection that significantly exceeds the standard industry terms. ### Is the REC Alpha Pure-R series still available for purchase, or has it been discontinued? The REC Alpha Pure-R series has been discontinued and superseded by the next-generation REC Alpha Pure-RX, which entered production at REC's Singapore manufacturing facility in early 2024. Direct orders are no longer fulfilled by the manufacturer, though some authorized distributors may still carry remaining inventory. If you are interested in REC's HJT technology, contact a local REC partner to check current stock or inquire about the successor Alpha Pure-RX series. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Web_DS_REC_Alpha_Pure-R_EN_US-147130a4556e.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 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
