REC Alpha Black REC355AA Black

  • REC’s pioneering and award-winning ‘Twin Panel’ design: Introduced in 2014, this delivers demonstrably better performance in shaded conditions.
  • REC’s commercialized half-cut cell technology: The Alpha features high efficiency n-type mono wafers between thin layers of amorphous silicon.
  • REC’s unique frame design: The 30 mm thin frame construction allows more panels per pallet, an easy installation and allows the Alpha to withstand snow loads of 7000Pa.
  • Industry-leading warranty: 25-year product warranty on installations by REC Solar Professionals (otherwise 20 years), and a 25-year power output warranty.
  • Even better for the environment: Manufacturing of REC Alpha solar panels requires less energy, which is further reducing the carbon footprint.
