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
