TommaTech panels, read off the datasheets
TommaTech has 7 modules in the database, from 570 to 600 Wp.
Everything below is computed from those 7 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where TommaTech does not publish a figure, it is left out of the average rather than assumed.
The top of the range
The leaders of TommaTech'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
Shares are of the 7 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.
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.
- High-efficiency panels available (up to 23.2%)
- Strong warranty coverage averaging 30 years
- High-power panels available (up to 600W) for commercial applications
- Limited bifacial panel options
