REC Alpha Pure REC405AA Pure 405W Solar Panel

This is the REC Alpha; REC's latest multiple award-winning family of trailblazing solar panels, empowering 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 reliability of REC – REC Alpha is the solar panel of choice for home solar. How does REC do it and what does it mean for you?

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), REC Alpha panels generate more energy from the same area, getting more from limited spaces
  • REC Alpha Series delivers around 20% more power on your roof compared to conventional panels

REC Alpha Pure Series: lead free + higher power density

  • REC Alpha Pure Series variant offers next-level power and greater environmental impact
  • Innovative gapless cell layout uses the entire panel surface to generate power
  • Highly impressive power density of 219 watts/m², with panel power reaching 405 Wp
  • Lead-free* for less environmental impact
  • Lead removed from all panel components, including cell connections, cross connectors and junction box soldering
  • Seamless appearance, lead-free construction, and high power make it a compelling solar panel for rooftops

    * ROHS compliant
