The top of the range

The leaders of Amerisolar'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

What the catalogue is made of

Cell technology across the market

Shares are of the 27 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
PERC 74.1% 20 TOPCon 25.9% 7
PERC accounts for 74.1% of the catalogue - 20 of 27 modules.
