Out of nowhere in 2019 the REC TwinPeak 2 Series went from being a somewhat respected solar panel option to almost one of the most appealing solar panel options available. What happened? A resounding shift brought on by two major changes.

.

Make and model:  REC TwinPeak 2 Series.

Variants:  275 | 280 | 285 | 290 | 300W.

  Durability, Performance.

  Module efficiency.

.

The evolution of an InterSolar 2015 award winning panel, the REC TwinPeak by today’s standard has become renowned as product of high-end innovation and now more so affordability for such distinguished innovation. True, not a mono-crystalline solution, the renewed appeal now possess unequaled characteristics unmatched by any other

Design.

Will you ever find a better ranked multicrystalline solar panel to pass the Solar Review Module Assessment Design Criteria? Armed with an Intersolar Award, most probably not. The REC TwinPeak 2 Series presents a better overall design than many monocrystalline solar panels available.

TwinPeak 2 Series - Design
  • Multicrystalline.
  • Up to 6-wire bus bar.
  • PERC enhanced.
  • Glass-laminate (White).
  • Innovative.
  • InterSolar award 2015.
  • DNV-GL certified.

Durability.

Durability of the REC TwinPeak 2 Series presents as VERY GOOD when subjected to the Solar Review Module Assessment Criteria. Notably, Salt mist and Hail resistance is high-calibre when compared to the industry average, areas of intense wind loading and desert conditions (thermal cycles) may seek greater specifications.

  1. These are awesome panels, I was wondering can you mount these in a motorhome? I only see them on residential buildings. Not sure if the road vibration would damage them
