The REC Alpha Pure-RX series represents a breakthrough in heterojunction (HJT) technology, offering the highest power density in the residential module segment. Thanks to the use of contactless HJT cell technology, these panels eliminate energy losses and ensure excellent performance even in low-light conditions. The uniqueness of this line is based on an innovative gapless layout, which allows for maximum utilization of the available roof area. This is an ideal solution for investors with limited space who do not want to compromise on maximum energy yields. Lead-free eco-friendly construction makes the RX series one of the most environmentally friendly products on the market, which is confirmed by compliance with strict RoHS certifications. The unique design with two independent sections allows the module to work even under partial shading, which directly translates to stable electricity production in difficult installation conditions. Solid frame reinforcements protect the panel against extreme weather phenomena, ensuring peace of mind for years. 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.

What owners get
Contactless HJT cell technology

The heterojunction cell structure eliminates metallic contact points between busbars and the cell, reducing microcracks and resistive losses. The manufacturer declares only 0.25% annual degradation versus the typical 0.4-0.55% seen in PERC or TOPCon panels.

Gapless layout for maximum power density

The innovative gapless cell arrangement delivers up to 470 Wp within a footprint typical of 60-cell modules, making this series one of the most power-dense options in the residential PV segment.

Two independent module sections

Splitting the panel into two electrically independent sections reduces output loss under partial shading (e.g., from a chimney or antenna), a meaningful advantage over standard 3-diode module designs.

Tier-1 bankable, manufacturer with 30 years of history

REC (Norway, founded 1996) is listed on the BNEF Tier 1 Bankable list, easing project financing and insurance approval - important for commercial and credit-financed installations.

Lead-free construction (RoHS)

The panel meets strict RoHS standards thanks to lead-free soldering, simplifying end-of-life recycling and compliance with increasingly stringent EU regulations on PV waste.

Trade-offs
Efficiency trails segment leaders

Efficiency of 21.6-22.6% is notably lower than comparably rated peers - Recom Lynx (23.52%), Trina Vertex S+ Shield i-TOPCon Ultra (23.5%), and Astronergy ASTRO N7s 2.0 (23.5%) - despite a similar 470 Wp max power output.

Full 25-year product warranty requires registration

REC's standard product warranty is 20 years; achieving the stated 25-year coverage requires enrollment in the REC ProTrust program, adding an administrative step for the investor or installer.

Common questions

6 answered
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.
