The top of the range

The leaders of Solaria'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 Solaria PowerX-400R Monocrystalline 400 Wp 20.5% 2 PowerXT 430R-PL Monocrystalline 430 Wp 20.4% 3 Solaria PowerXT-400R-PM Monocrystalline 400 Wp 20.2% 4 Solaria PowerX-395R Monocrystalline 395 Wp 20.2% 5 Solaria PowerX-390R Monocrystalline 390 Wp 20.0%
For a commercial array 500 Wp and up

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
Unknown 66.7% 18 TOPCon 18.5% 5 PERC 14.8% 4
Unknown accounts for 66.7% of the catalogue - 18 of 27 modules.

Strengths and gaps

Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built.
