SoliTek is a European solar panel and energy storage manufacturer headquartered in Vilnius, Lithuania, and is the largest solar module producer in Northern Europe. Part of the family-owned BOD Group, the company operates a fully automated production line with approximately 250 MW...

Everything below is computed from those 49 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Solitek does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of Solitek'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 49 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 98.0% 48 Unknown 2.0% 1
TOPCon accounts for 98.0% of the catalogue - 48 of 49 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
  • High-efficiency panels available (up to 23.2%)
  • Strong bifacial lineup - 100% of portfolio supports dual-sided generation
  • Strong warranty coverage averaging 30 years
  • High-power panels available (up to 720W) for commercial applications
  • Large-scale production capacity of 0.1-0.5 GW
Where it is thin
  • Average efficiency of 20.4% is below the industry leading edge
