Exiom panels, read off the datasheets

Exiom is a European solar module manufacturer with production facilities in Spain. The company focuses on producing high-quality photovoltaic modules for the European market, emphasizing local manufacturing and short supply chains.

Everything below is computed from those 39 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Exiom does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of Exiom'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.

02

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.

03

What the catalogue is made of

Cell technology across the market

Shares are of the 39 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
PERC accounts for 69.2% of the catalogue - 27 of 39 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.
