Despite premium HJT technology, REC does not lead on this metric. - **No bifacial variant available** - The series is offered only in a monofacial configuration, ruling out additional rear-side energy gains (typically 3-10% depending on ground albedo) available in some competing premium modules of the same power class. ## About this series The REC Alpha Pure-RX series redefines performance standards through the use of advanced **heterojunction cells (HJT)** in a seamless design. The innovative cell layout completely eliminates gaps between them, allowing for maximum utilization of the available roof area. This is the ideal solution for demanding homeowners who have limited space but expect the highest energy yields from every square meter. Thanks to the proprietary **Twin Design** technology, the modules operate efficiently even in partial shading conditions, which provides a significant advantage over standard competitor solutions. This series stands out on the market for its eco-friendly approach, being completely **lead-free** in accordance with RoHS certification. Robust construction with additional frame supports guarantees resistance to strong wind and heavy snow, ensuring the safety of the installation for decades. By choosing these panels, you gain not only elegant Full Black aesthetics, but above all the **highest power density** and unrivaled durability. This is a premium-class product dedicated to residential installations where reliability and care for the environment are a priority. ## Notable figures - Efficiency of 22.3% matches the \*\*HJT 450-500W\*\* median - 223.3 W/m² power density is 4.4 W/m² below \*\*HJT 450-500W\*\* median (227.7 W/m²) - requires larger installation area - Temperature coefficient of -0.24%/°C matches the \*\*HJT 450-500W\*\* median - #5100 for efficiency, #13 for temperature performance out of 14005 panels ## Questions ### Do REC Alpha Pure-RX panels perform well in summer heat? Yes — the HJT technology used in the Pure-RX series features an exceptionally low temperature coefficient of just -0.24%/°C for peak power (Pmax). This means the modules lose significantly less output in hot weather compared to standard PERC panels (typically -0.35%/°C). In practice, during a hot summer, the daily energy yield difference can reach several percentage points in favor of this series. ### What warranty does the REC Alpha Pure-RX series come with? REC provides a 25-year product warranty covering material and workmanship defects, plus a 25-year linear power warranty guaranteeing at least 92% of rated power after a quarter century of operation. This is among the longest warranties in the premium segment. By comparison, standard PERC modules from many manufacturers offer only a 12-year product warranty. ### What is the efficiency and power density of the REC Alpha Pure-RX 470W panel? The 470 Wp model achieves up to 22.6% efficiency at a power density of 226 W/m², among the highest figures available in the residential module market. The seamless layout of 88 HJT half-cut cells eliminates dead zones between cells entirely, allowing the Pure-RX series to extract maximum output from every square meter of roof area — ideal for small or constrained roof sections. ### What is Twin Design technology in the REC Alpha Pure-RX series and how does it help with shading? Twin Design is REC's proprietary wiring layout that divides the module's cells into two independent groups. When a shadow falls on part of the panel — from a chimney or dormer, for example — the shaded half does not fully block the unshaded half from generating power. In practice, Pure-RX modules handle partial shading better than conventional single-string modules, resulting in higher daily energy yields on challenging rooftops. ### What are the dimensions and weight of the REC Alpha Pure-RX panel — will it fit on a standard gable roof? The REC Alpha Pure-RX measures 1728 × 1205 × 30 mm and weighs 22.7 kg. This is a compact footprint for a 470 Wp module, fitting comfortably on a typical residential gable roof. At 22.7 kg per module, the panel stays within the safe two-person manual installation threshold and requires no crane or special lifting equipment. ### Is the REC Alpha Pure-RX series certified as lead-free and does it matter in practice? Yes — the Pure-RX series holds RoHS certification and is entirely lead-free, setting it apart from many competing modules. This has real environmental significance: eliminating lead reduces the risk of soil contamination in the event of module damage. REC Group, headquartered in Norway, applies strict ecological standards across all stages of its manufacturing process. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DS_Alpha_Pure-RX_IEC_EN_AUCEC_101125-e388e010a972.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +45 W, +2.7 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +30 W, +2.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +40 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +25 W, +2.2 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +35 W, +2.2 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +35 W, +2.2 pp, +5 yr warranty | | [REC REC450AA PURE-RX](https://comparepv.com/panel/rec-rec450aa-pure-rx) | 450 W | -15 W, -0.7 pp | | [REC REC455AA Pure-RX](https://comparepv.com/panel/rec-rec455aa-pure-rx) | 455 W | -10 W, -0.4 pp | | [REC REC460AA PURE-RX](https://comparepv.com/panel/rec-rec460aa-pure-rx) | 460 W | Very close match | | [REC REC470AA PURE-RX](https://comparepv.com/panel/rec-rec470aa-pure-rx) | 470 W | +0.3 pp | | [REC REC Alpha Pure-RX 470 Wp](https://comparepv.com/panel/rec-rec-alpha-pure-rx-470-wp) | 470 W | +0.3 pp | --- Source: https://comparepv.com/panel/rec-rec465aa-pure-rx Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
