VSUN panels, read off the datasheets
VSUN has 111 modules in the database, from 390 to 715 Wp.
Everything below is computed from those 111 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where VSUN does not publish a figure, it is left out of the average rather than assumed.
The top of the range
The leaders of VSUN'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 111 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.
- Solid portfolio of 111 panels
- High-efficiency panels available (up to 23.1%)
- Strong bifacial lineup - 75% of portfolio supports dual-sided generation

Compared with
A brand comparison weighs the two catalogues against each other - what each builds, at what efficiency, and how deep the range goes.
