Everything below is computed from those 111 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Q-SUN Solar does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of Q-SUN 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 111 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
N-type 42.3% 47 PERC 35.1% 39 TOPCon 18.0% 20 HJT 4.5% 5
N-type accounts for 42.3% of the catalogue - 47 of 111 modules.
Efficiency spread share of the catalogue
