1. Company Overview
REC Group was founded in Norway in 1996 and built its early reputation as a vertically integrated silicon, wafer, and module producer. Today the company is headquartered in Singapore, with its primary manufacturing operations in Singapore. In 2021, REC was acquired by Reliance Industries, the Indian conglomerate, which has continued to invest in REC's HJT technology roadmap. REC has shipped over 12 GW of modules globally and is a BloombergNEF Tier 1 manufacturer.
REC positions itself firmly in the premium residential market, competing on efficiency, aesthetics, and warranty rather than lowest price-per-watt. The Alpha series, launched in 2019, was the first high-volume heterojunction panel from a major Western-brand manufacturer and remains REC's flagship platform.
2. Current Product Lines
REC's active lineup is built on the Alpha heterojunction (HJT) cell platform, evolved through several generations:
- REC Alpha Pure — The entry-level HJT series, the most affordable heterojunction cell option in REC's lineup. Power output ranges from 360 W to 410 W ([EcoWatch](https://www.ecowatch.com/solar/best-companies/rec-review)).
- REC Alpha Pure-R — The refined residential HJT series with 400–430 Wp output, up to 22.3% max efficiency, a -0.24%/°C temperature coefficient, and a 25-year guarantee of at least 92% power output ([REC datasheet](https://krannich-solar.com/fileadmin/user_upload/US/Datasheets/Modules/REC/REC_Alpha_Pure-R-EN_US_0.pdf)).
- REC Alpha Pure-RX — The flagship residential HJT module, reaching up to 470 W and 22.6% max efficiency (REC470AA Pure-RX), with >92% power guaranteed in year 25, 55 mm hail resistance, and an exceptional -0.24%/°C temperature coefficient ([REC datasheet](https://www.recgroup.com/sites/default/files/2025-04/Web_DS_REC%20Alpha%20Pure-RX_EN%20US_042025.pdf); [SolarTech Online](https://solartechonline.com/blog/rec-solar-panels-review-2025/)).
- Legacy Alpha (first generation) — The original 360–380 Wp HJT module, carrying a 20-year product warranty and 25-year linear power output guaranteeing 86% at year 25 ([REC datasheet](https://es-media-prod.s3.amazonaws.com/media/components/panels/spec-sheets/REC_Solar_alpha.pdf)).
3. Recent Releases (2025–2026)
REC's current flagship is the Alpha Pure-RX, which pushes the residential HJT platform to 470 W and 22.6% efficiency — the highest in REC's lineup. The Pure-RX features an industry-leading temperature coefficient of -0.24%/°C (improved from -0.26%/°C on the Pure-R series), 55 mm hail resistance, and mechanical load ratings of +7000 Pa / -4000 Pa with four-point clamping (upgradeable to +10000 Pa / -6000 Pa with six-point clamping) ([REC datasheet](https://www.recgroup.com/sites/default/files/2025-04/Web_DS_REC%20Alpha%20Pure-RX_EN%20US_042025.pdf)).
The Pure-RX also guarantees >92% of rated power in year 25 — one of the strongest retained-output guarantees in the residential market, reflecting HJT's inherently low degradation rate of approximately 0.25% per year ([SolarTech Online](https://solartechonline.com/blog/rec-solar-panels-review-2025/)). REC continues to refine the HJT cell architecture rather than transitioning to TOPCon, betting that HJT's superior temperature behavior and low degradation will remain competitive at the premium end.

5. Warranty Terms
REC offers one of the most comprehensive warranty packages in the premium residential segment:
- Product (materials/workmanship) warranty: 20 years — among the longest standard product warranties in the industry ([REC datasheet](https://es-media-prod.s3.amazonaws.com/media/components/panels/spec-sheets/REC_Solar_alpha.pdf); [Premiere Electrical Renewables](https://premierelectricalrenewables.co.uk/products/rec-alpha)).
- Performance warranty: 25-year linear power output guaranteeing a minimum of 92% of rated power at year 25 on the Pure-RX, with maximum annual degradation of just 0.25%/year ([REC datasheet](https://www.recgroup.com/sites/default/files/2025-04/Web_DS_REC%20Alpha%20Pure-RX_EN%20US_042025.pdf)).
The 92% retained-output guarantee at year 25 is exceptional — most competitors guarantee only 80–87% over the same period. REC's RecProTrust warranty program offers additional installer benefits including extended coverage and streamlined claims processing. As a PES Supply authorized dealer, you file claims through our support team using your PES Supply invoice as proof of purchase.

| Model | Watts | Cell Tech | Efficiency | Dimensions | Warranty | Price Range |
|---|---|---|---|---|---|---|
| REC Alpha Pure | 400–410 W | HJT | 21.0–22.0% | 1721 × 1016 × 30 mm | 20-yr product / 25-yr power (92%) | $0.45–$0.55/W |
| REC Alpha Pure-R | 400–430 W | HJT | 21.8–22.3% | 1720 × 1118 × 30 mm | 20-yr product / 25-yr power (92%) | $0.48–$0.58/W |
| REC Alpha Pure-RX (REC450/460/470) | 450–470 W | HJT | 22.0–22.6% | 1730 × 1118 × 30 mm | 20-yr product / 25-yr power (92%) | $0.50–$0.62/W |
| REC Alpha (legacy 380Wp) | 360–380 W | HJT | 20.0–21.0% | 1721 × 1016 × 30 mm | 20-yr product / 25-yr power (86%) | $0.42–$0.52/W |
The Pure-RX reaches 470 W at 22.6% efficiency with a 92% year-25 power guarantee ([SolarTech Online](https://solartechonline.com/blog/rec-solar-panels-review-2025/)). Prices are contractor estimates and vary with volume and market conditions.
8. Technical Comparison
| Brand | Flagship Tech | Peak Efficiency | Product Warranty | Year-25 Output | Price Position |
|---|---|---|---|---|---|
| REC | HJT (Alpha) | 22.6% | 20 yr | 92% | Premium |
| JA Solar | N-type TOPCon | 24.8% (5.0) | 25 yr | ~87% | Mid-range (value) |
| LONGi | HPBC 2.0 BC | 24.8% | 15–25 yr | ~87% | Mid-range |
| Canadian Solar | HJT (HiHero) | 23.9% | 12 yr | ~87% | Mid-range |
REC cannot match the raw peak efficiency of the latest Chinese TOPCon flagships (24.8%), but it leads on two metrics that drive real-world yield: a -0.24%/°C temperature coefficient (versus ~-0.29 to -0.35%/°C for PERC/TOPCon) and a 92% year-25 retained output guarantee. In hot climates and over the module lifetime, these advantages can offset the lower nameplate efficiency. The tradeoff is a premium price point of $0.45–$0.62/W versus $0.26–$0.34/W for value-tier TOPCon modules.

10. Frequently Asked Questions
What is heterojunction (HJT) technology?
HJT combines crystalline silicon with thin amorphous silicon layers to create a cell with excellent passivation, very low temperature sensitivity, and minimal degradation. The result is higher real-world yield in hot conditions and stronger retained output over the module lifetime.
What is the difference between REC Alpha Pure-R and Pure-RX?
The Pure-R reaches up to 430 W at 22.3% efficiency. The Pure-RX is the flagship, reaching 470 W at 22.6% efficiency with an improved -0.24%/°C temperature coefficient, 55 mm hail resistance, and higher mechanical load ratings ([REC datasheet](https://www.recgroup.com/sites/default/files/2025-04/Web_DS_REC%20Alpha%20Pure-RX_EN%20US_042025.pdf)).
Why does REC guarantee 92% power at year 25?
HJT cells degrade at only ~0.25%/year, far slower than PERC (~0.55%/year) or standard TOPCon (~0.4%/year). This allows REC to guarantee 92% retained output at year 25, versus the 80–87% typical of competing technologies.
Are REC panels Buy America-compliant?
No. REC manufactures in Singapore, so its modules do not meet Buy America or BABA requirements. PES Supply offers BABA-compliant US-made options from Mission Solar and Silfab for federally funded projects.
What is the lead time from PES Supply?
In-stock REC Alpha modules ship within 7–10 business days delivery. Contact our sales team for project-scale allocation and ETAs on specific Pure-RX configurations.
