A few places in the rankings can mean less than half a point.
Scores in every category sit close together, so a product can move several places on a change smaller than half a point. Read the score and its class before the position.
Most neighbouring scores are within half a point
Between neighbouring current panel scores, 114 of 128 gaps are half a point or less.
For batteries it is 76 of 89.
For inverters it is 86 of 101.
TiesMany products share a score outright
72 of 129 current panels share their exact one-decimal score with at least one other panel.
On the whole-number score shown on product cards, as many as 16 panels share one value.
Tied products share a rank, as the site ranks them: two products on the same score both take the higher place, and the next product skips a place.
Reading a rankRead the score and class before the position
The figures cover the 321 current panels, batteries and inverters; retired, pre-release, thin-film and plug-in storage records are left out.
The newest product evidence behind these scores was checked on 2026-09-12.
A rank gap is a count of products, not a size of difference. Where neighbours sit this close, a small correction to one sourced value can move a product several places without changing what the evidence says about it. Compare the scores themselves, and compare within the product's class.
