PolyCrown Solar Tech panels, read off the datasheets

They have passed ISO9001, ISO14001, and OHSAS18001 system certifications, as well...

Everything below is computed from those 75 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where PolyCrown Solar Tech does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of PolyCrown Solar Tech'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 75 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 46.7% 35 Unknown 44.0% 33 TOPCon 9.3% 7
N-type accounts for 46.7% of the catalogue - 35 of 75 modules.
Efficiency spread share of the catalogue
