Building on REC's multiple award-winning innovations, the REC Alpha Pure family of solar panels empowers you to take full advantage of solar energy. Packing in cutting-edge technologies to deliver higher power density, stunning aesthetics, and minimal environmental impact  all with the renowned quality of REC – the Alpha Pure family from REC are the solar panels of choice for home solar. How does REC do it and what does it mean for you?
Get more power with REC Alpha Heterojunction (HJT) cell technology

Heterojunction (HJT) cell technology

  • No LID = no power loss; you get the power you pay for
  • Leading temperature coefficient means more energy as temperature rises
  • Higher power for greater savings and accelerated return on investment
  • With high power density (watts/m²), panels in REC Alpha Pure family generate more energy from the same area, getting more from limited spaces
REC Alpha Advanced Cell Connection Technology

Advanced cell connection technology

  • Increased number of wires greatly improves flow of electricity current
  • Eliminating invasive soldering removes risk of cell damage or microcracks for long-lasting high performance
  • Stylish looks thanks to thin, barely-visible wires and uniformly black-colored cells
  • Full-black variant is a design masterpiece and the most elegant feature for your home
  • Solder-free cells
  • Environmentally-friendly manufacturing drastically reduces carbon footprint

Gapless cell layout

  • Innovative gapless cell layout increases active area of the panel to capture more sunlight
  • Boosts power density to impressive 226 watts/m², with panel power reaching 470 Wp
  • Higher power in a compact panel size
  • Elegant full-black design
  • 9A current of REC Alpha Pure-R & Pure-RX panels ensures MLPE compatibility
REC Alpha produces power even when shaded

Pioneering panel designs

  • REC's award-winning and iconic Twin design splits the REC Alpha Pure into two ‘Twin’ sections
  • Reduces internal resistance for more power and reliability
  • Continued energy production in shaded conditions means you see higher energy yields
  • REC Alpha Pure-R & Pure-RX take this further and divide the panel into four sections, producing even more energy in shade
REC Alpha super-strong frame guarantees better durability

Super-strong frame

  • Support bars protect cells and glass from bending under load
  • Allows extreme loads up to 7000 Pa
  • Panels maintain high performance levels over the installation lifetime
  • 30 mm frame height makes panel easier to handle
  • Frame design allows optimized transportation: more panels/pallet = more panels/container = fewer trucks on the road = more savings

Lead free

  • Lead-free*
  • Lead removed from all panel components, including cell connections, cross connectors and junction box soldering
  • No toxic leakage of lead after recycling
  • Enables homeowners to boost environmental impact and lower overall carbon footprint even more

*RoHS compliant
