Sunman panels, read off the datasheets
Sunman Energy is a technology company pioneering ultra-light, glass-free crystalline silicon solar modules under its proprietary eArc technology — the world's first such product, weighing up to 70% less than conventional glass panels. Founded by Dr. Zhengrong Shi (the founder of Suntech),...
Everything below is computed from those 6 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Sunman does not publish a figure, it is left out of the average rather than assumed.
The top of the range
The leaders of Sunman'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 6 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.
- Strong warranty coverage averaging 25 years
- Large-scale production capacity of 1-2 GW
- Average efficiency of 17.7% is below the industry leading edge
- Limited bifacial panel options
- Limited adoption of latest cell technologies (TOPCon/HJT)
In short
Is Sunman a good solar panel manufacturer?
What types of solar panels does Sunman make?
How efficient are Sunman solar panels?
What warranty does Sunman offer on their solar panels?
Are Sunman panels good for residential use?
Compared with
A brand comparison weighs the two catalogues against each other - what each builds, at what efficiency, and how deep the range goes.
