You’ve done a fair amount of research into this solar power thing and discovered a considerable price difference between what has been identified as the best solar panel technology available and some fairly average stuff referred to as Tier-1. Therefore, is it worth paying thousands more for the for some the popular high performers or is there a more affordable option which could be just as good?


Make and model:  REC N-Peak.

Variants: 315W/ 320W / 325W / 330W

Unless you enjoy throwing hard earned money down the toilet, avoid anything labelled Tier-1. If a business or person has had to resort to labelling a solar panel Tier-1, there are actually no superior qualities worth mentioning and the warranty isn’t worth the paper it’s printed on. Now consider REC Solar’s latest release, the REC N-Peak. Could this finally be the happy medium we’ve all been searching for?

As a respected name within the solar panel manufacturing industry and equipped with a new higher watt class, the 6 essential criteria of design, durability, efficiency, performance, guarantee and affordability must still be assessed.


2019 will see more half cell designs than ever before. Uncharacteristic of previous REC Solar panels, the REC N-Peak has incorporated an N-Type mono PERT solar cell (not PERC) which will also adopt the advanced half cell design. Similar to past REC Twin-Peak variants, the REC N-Peak offers advanced optimisation from specific shading exposure by splitting a conventional panel design into two identical mirrored sections and integrating a modified bypass diode layout.

A new and improved minimalist ultra slimline 30mm black anodised frame is now included. A design aspect sure to appeal to those concerned about aesthetics. Black and white back-sheet variants are available, although, a white back-sheet will always outperform a black back-sheet in almost any given environment.

N-Peak Series Design; ELITE
  • N-Type Monocrystalline cell.
  • 5 front bar contact.
  • PERC enhanced.
  • Glass-laminate (White).
  • Innovative.
  • InterSolar award.
  • DNV-GL certified.


Even with a new reduced frame dimension, consider the REC N-Peak the strongest REC Solar module yet and potentially one of the more durable solar modules available due to a reinforced frame design. Integrating 2 support bars through the middle of the panel ensures protection from loads up to an outstanding 7000 Pa (IEC Standard: 5400 Pa). Additionally the support bar design further increases durability against bending and deformation over time.

Beyond additional strength, the REC N-Peak presents excellent resistance against salt mist (coastal), ammonia (agriculture) and above average protection against extreme temperature changes (desert conditions) or humidity as identified below.

Opposed to P-Type mono silicon, N-Type is the most efficient mono-crystalline cell technology available. Incorporating N-Type mono silicon cells is major upgrade from REC, as it’s the foundation of the solar module being now able to achieve efficiencies up to 19.8%. An excellent efficiency made even more respectable when considering a temperature coefficient of only -0.35%C (Tier-1 Average -0.40%C).
