The top of the range

The leaders of Corab's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof.

By what the array is for

Three cuts of the same catalogue, each ordered by efficiency inside its band. An empty column means the brand does not build for that case.

What the catalogue is made of

Cell technology across the market

Shares are of the 5 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one.

Strengths and gaps

Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built.

What this catalogue is good at
  • Strong warranty coverage averaging 25 years
  • Established manufacturer with 33+ years of experience
  • Large-scale production capacity of 2.5 GW
Where it is thin
  • Average efficiency of 20.6% is below the industry leading edge
  • Limited bifacial panel options
  • No high-power panels (500W+) available for commercial use
  • Limited adoption of latest cell technologies (TOPCon/HJT)
