REC panels, read off the datasheets

REC has 58 modules in the database, from 105 to 640 Wp.

Everything below is computed from those 58 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where REC does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of REC'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 58 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.

Cell technology share of the catalogue
HJT 58.6% 34 Unknown 37.9% 22 N-type 3.4% 2
HJT accounts for 58.6% of the catalogue - 34 of 58 modules.
Efficiency spread share of the catalogue
