Heterojunction (HJT) cell technology
  • No LID = no power loss; you get the power you pay for
  • Higher efficiencies at the hottest times; this leading Temperature Coefficient means more energy than other panels when the sun shines strongest and in hot conditions
  •  Higher power for greater savings and accelerated return on investment
  • High power density (watts/m²) generates more energy from the same area, getting more from limited spaces
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
  • 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 223 watts/m², with panel power reaching 430 Wp
  • Higher power in a compact panel size
  • Elegant full-black design
  • 9A current ensures MLPE compatibility
Pioneering panel designs
  • Innovative layout takes REC's award-winning and iconic Twin design further and divides the panel into four sections, producing even more energy in shade
  • Continued energy production in shaded conditions means you see higher energy yields
  • Reduces internal resistance for more power and reliability
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
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
Premium solar panel warranty
  • Product warranty: 20 years – covers panel defects
  • Performance warranty: 25 years – with 0.25% warranted annual degradation, REC Alpha Pure-R will still produce at least 92% of its nameplate power in its 25th year of operation
  • Eligible for REC ProTrust*, a comprehensive package that offers a 25-year warranty for each of product, performance, and labor: get an additional five years on the 20-year product warranty, plus a labor warranty for up to 25 years

*REC ProTrust Warranty applies only for (i) REC panels installed by an REC Certified Solar Professional, and ii) panels have been registered by the installer with REC. Subject to System Size and further conditions.
