The top of the range

The leaders of DAH 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.

For a house roof 380-460 Wp
1 DHN-54R20/DG(BW) 460W Monocrystalline bifacial 460 Wp 23.0% 2 DHN-54R20/DG-460 Monocrystalline bifacial 460 Wp 23.0% 3 DHN-54R20/DG(BW)-460 Monocrystalline bifacial 460 Wp 23.0% 4 DHN-54R20/DG(BW) 455W Monocrystalline bifacial 455 Wp 22.8% 5 DHN-48Z20/DG(BB)-455W Monocrystalline bifacial 455 Wp 22.8%

What the catalogue is made of

Cell technology across the market

Shares are of the 363 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 87.9% 319 PERC 12.1% 44
TOPCon accounts for 87.9% of the catalogue - 319 of 363 modules.
