REC Solar REC420AA-PURE-R Alpha Series 420 Watt Module

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 – REC Alpha Pure and Pure-R are the solar panels of choice for home solar.

 

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 16% more power on your roof compared to conventional panels

 

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 cell

  • 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

 

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 takes this further and divides the panel into four sections, producing even more energy in shade

 

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 (1.8") 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

 

Industry-leading Warranty

  • 25 year product warranty*: covers any panel defects

  • 25 year performance warranty: ensures panels perform exactly as they’re expected to – every year for 25 years

  • 25 year labor warranty*: gives added protection in case a panel needs to be serviced

  • At least 92% of nameplate power in year 25; an industry best

  • Unprecedented savings, more economic security, and greater energy autonomy for consumers

  • * when installed by a REC Certified Solar Professional installer; part of the REC ProTrust Warranty
