JS Solar panels, read off the datasheets

JS Solar has 137 modules in the database, from 200 to 670 Wp.

Everything below is computed from those 137 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where JS Solar does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of JS Solar'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 137 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 55.5% 76 PERC 38.7% 53 TOPCon 5.8% 8
Unknown accounts for 55.5% of the catalogue - 76 of 137 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.

What this catalogue is good at
  • Solid portfolio of 137 panels
  • Strong warranty coverage averaging 25 years
  • High-power panels available (up to 670W) for commercial applications
Where it is thin
  • Average efficiency of 20.0% is below the industry leading edge
