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

The renewed appeal. Compare the essential Solar Review Solar Module criteria of design, durability, efficiency, performance, guarantee and affordability against the industries best specifications below.

REC Solar Module

For the multicrystalline cell type, temperature coefficient of the REC TwinPeak 2 Series should be considered OUTSTANDING. Although a limited 18% maximum module efficiency of up to 18%, the efficiency qualities which surround that are respectable. That of which includes a +5W (3%) positive power tolerance.

REC Solar

TwinPeak 2 Series - Efficiency
  • 18% Maximum module efficiency.
  • -0.36%°C Temperature coefficient.
  • 0/3% Power tolerance.

A common solar panel performance score for internationally respected solar module brands. The REC TwinPeak 2 Series pulls no hidden surprises in relation to promised performance overtime. 2.5% degradation within the first year is admirable. 0.7% degradation each year after has become the minimum expected from a linear performance guarantee. 

REC Solar

TwinPeak 2 Series - Performance
  • 2.5% degradation in the 1st year.
  • 0.7% degradation per annum.
  • 25-year linear performance warranty.
  • Parts & service performance warranty.
