The top of the range

The leaders of Heckert Solar'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 155 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
TOPCon 33.5% 52 PERC 29.7% 46 Unknown 22.6% 35 Back Contact 12.9% 20 N-type 1.3% 2
TOPCon accounts for 33.5% of the catalogue - 52 of 155 modules.
