DMEGC panels, read off the datasheets

DMEGC Solar, founded in 1980, is a global provider of renewable energy solutions, specializing in high-efficiency solar panels for residential, commercial, and utility-scale projects. The company has six manufacturing bases and is known for its integrated supply chain, from wafers to modules....

Everything below is computed from those 150 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where DMEGC does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of DMEGC'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 150 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 72.7% 109 N-type 27.3% 41
TOPCon accounts for 72.7% of the catalogue - 109 of 150 modules.
