Who is in the catalogue
190 manufacturers publish at least one module we can read. The largest catalogue holds 654 panels; the median holds far fewer, and a brand with four modules sits in the same table as a brand with five hundred.
That makes every average on this page a figure that needs its denominator. A catalogue average rewards a narrow premium range and punishes breadth, so the panel count is printed beside each one and thin catalogues are marked. Read the averages as "what this brand mostly sells", never as "how good this brand is".
Who ships the most
Catalogue size, which is a measure of breadth and nothing else.
A large catalogue usually means a full range from budget to flagship, which pulls the brand's average towards the middle of the market while its best module sits at the top of it.
A small catalogue can be a specialist with one excellent product line, or a rebadger with four. The count beside each average is what tells them apart, and the lists below mark anything under twenty panels in amber.
Who is good at what
Three different questions with three different answers. No brand leads all of them.
Density and technology mix
The technology mix across every panel that declares one. Individual brands sit a long way from this average: a catalogue built in the last two years is mostly TOPCon, one that has not been refreshed is mostly PERC. 12,962 panels declare a technology.
How these numbers are built
Every figure comes from a manufacturer datasheet ingested into the panel database. Nothing is modelled, estimated, or supplied by a brand outside its own published specification.
Aggregates recompute as new panels arrive. A panel that does not declare a value is left out of that average rather than filled in, so every figure here is backed by modules that actually publish it.
No paid placements, and no figure here reads which shops pay us a commission. Each power rating counts as the module it is. Bifacial datasheets that quote one module at several assumed rear-side gains are counted once, on their front-side rating.
