Growatt panels, read off the datasheets
Growatt has 1 modules in the database, from 150 to 150 Wp.
Everything below is computed from those 1 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Growatt does not publish a figure, it is left out of the average rather than assumed.
The top of the range
The leaders of Growatt'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.
What the catalogue is made of
Shares are of the 1 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.
- Average efficiency of 18.6% is below the industry leading edge
- Limited bifacial panel options
- No high-power panels (500W+) available for commercial use
- Limited adoption of latest cell technologies (TOPCon/HJT)
