By choosing REC Alpha Pure-RX, you invest in **the highest durability confirmed by a multi-year warranty**, which sets this product apart from standard competition offering less advanced TOPCon or PERC cells. ## Notable figures - Module efficiency of 22.1% is 0.7pp below average for \*\*HJT 450-500W\*\* panels (median: 22.8%) - 220.9 W/m² power density is 6.8 W/m² below \*\*HJT 450-500W\*\* median (227.7 W/m²) - requires larger installation area - At -0.24%/°C, hot weather performance is typical for \*\*HJT 450-500W\*\* panels - Ranked #6012 out of 14005 panels for efficiency in the database ## Questions ### How do REC Alpha Pure-RX panels differ from standard TOPCon or PERC modules? REC Alpha Pure-RX uses HJT (Heterojunction Technology), combining an amorphous silicon passivation layer with a monocrystalline wafer. The result is efficiency up to 22.6% and an exceptionally low temperature coefficient of -0.24%/°C, meaning less power loss in summer heat compared to TOPCon or PERC modules. The series is also fully lead-free and RoHS-compliant, making it one of the more environmentally responsible choices on the market. ### How does the REC Alpha Pure-RX handle partial shading from a chimney or antenna? The REC Alpha Pure-RX features a four-section independent cell layout that limits energy losses when part of the module surface is shaded. In practice, this delivers more stable power output than conventional single-section panels and can reduce or eliminate the need for additional power optimizers or microinverters in many residential installations. ### What warranty does the REC Alpha Pure-RX come with and what does it cover? The REC Alpha Pure-RX series includes a 25-year product warranty and a 25-year power output warranty guaranteeing at least 91.1% of rated power after 25 years of operation. REC Group is a Tier 1 manufacturer headquartered in Norway with a strong financial track record, which significantly reduces the risk of warranty claims going unmet over the long term. ### Is the REC Alpha Pure-RX a bifacial panel and how much additional energy can it generate? Yes, the REC Alpha Pure-RX is a bifacial module capable of generating electricity from both the front side and rear side, capturing light reflected from surfaces such as a white roofing membrane, gravel, or snow. Depending on the albedo of the mounting surface and tilt angle, bifaciality can increase total annual energy yield by several percent compared to a conventional monofacial panel. ### Is the REC Alpha Pure-RX a good fit for a small roof with limited mounting space? Yes, the Alpha Pure-RX is one of the best solutions for roofs with limited available area. Its power density of 226 W/m² and gapless cell layout pack maximum output into the footprint available. The 470 Wp module measures 1728 × 1205 mm, making it straightforward to achieve a high combined system capacity without expanding the installation area. ### Do REC Alpha Pure-RX panels perform well in winter and on overcast days? Yes. HJT cell architecture delivers strong low-light performance due to minimal carrier recombination within the cell structure. The low temperature coefficient (-0.24%/°C) also means that on cold, sunny winter days REC Alpha Pure-RX modules outperform TOPCon or PERC panels, which typically carry a higher temperature coefficient. This is a notable advantage in climates with a high proportion of diffuse irradiance days. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Web_DS_REC_Alpha_Pure-RX_EN_US_042025-cbe7c5260a7b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, +2.9 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, +2.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, +2.6 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, +2.4 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, +2.4 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, +2.4 pp, +5 yr warranty | | [REC REC450AA PURE-RX](https://comparepv.com/panel/rec-rec450aa-pure-rx) | 450 W | -10 W, -0.5 pp | | [REC REC455AA Pure-RX](https://comparepv.com/panel/rec-rec455aa-pure-rx) | 455 W | -0.2 pp | | [REC REC465AA Pure-RX](https://comparepv.com/panel/rec-rec465aa-pure-rx) | 465 W | Very close match | | [REC REC470AA PURE-RX](https://comparepv.com/panel/rec-rec470aa-pure-rx) | 470 W | +10 W, +0.5 pp | | [REC REC Alpha Pure-RX 470 Wp](https://comparepv.com/panel/rec-rec-alpha-pure-rx-470-wp) | 470 W | +10 W, +0.5 pp | --- Source: https://comparepv.com/panel/rec-rec460aa-pure-rx Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
