REC Solar Alpha Pure Series 400 solar panel, 400Wp

First-class high-performance modules

Packing in cutting-edge technologies to deliver higher power density, stunning aesthetics, and minimal environmental impact - all with the renowned reliability of REC - REC Alpha is the solar panel of choice for home solar.

More energy from dawn to dusk

  • Leading temperature coefficient means more energy as temperature rises
  • Higher power for greater savings and accelerated return on investment
  • With high power density (216 watts/m²), REC Alpha panels generate 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
  • Environmentally-friendly manufacturing drastically reduces carbon footprint

Super-strong frame design

Two extra support bars across the rear of the panel reduces the bending and deformation of the panel under load while allowing loads of up to 7000 Pa.
