  • The world’s highest power 60-cell solar panel.
  • Greater amount of sunlight converted to electricity.
  • A beautiful solar panel with reinforced frame.
  • Over 20% more power from the same install.
  • All backed up by an industry-leading warranty.
  • This is the REC Alpha Series.

HJT Monocrystalline & Thin Film Technologies

Emerging from REC’s leadership in half-cut cell technology, the Alpha is built around 120 half-cut heterojunction cells (HJT) and advanced connection technology, designed by engineering experts from Germany and Singapore. With HJT, REC combines the benefits of N-Type monocrystalline silicon solar cells with those of thin film technologies for much higher efficiency and energy yield, even at higher temperatures.

REC Alpha REC350AA Benefits

  • 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.

REC is known for leading standards of design and manufacturing to produce long-lasting and high-performance solar panels with reliable power output.
