KB Solar panels, read off the datasheets

KB Solar has 5 modules in the database, from 365 to 385 Wp.

Everything below is computed from those 5 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where KB Solar does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of KB Solar'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.

For a house roof 380-460 Wp
1 KBS-385 Monocrystalline bifacial 385 Wp 20.9% 2 KBS-380 Monocrystalline bifacial 380 Wp 20.6%
For a ground mount dual-sided
1 KBS-385 Monocrystalline bifacial 385 Wp 20.9% 2 KBS-380 Monocrystalline bifacial 380 Wp 20.6% 3 KBS-375 Monocrystalline bifacial 375 Wp 20.3% 4 KBS-370 Monocrystalline bifacial 370 Wp 20.1% 5 KBS-365 Monocrystalline bifacial 365 Wp 20.0%

What the catalogue is made of

Cell technology across the market

Shares are of the 5 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 100.0% 5
PERC accounts for 100.0% of the catalogue - 5 of 5 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.

What this catalogue is good at
  • Strong bifacial lineup - 100% of portfolio supports dual-sided generation
  • Strong warranty coverage averaging 30 years
Where it is thin
  • Average efficiency of 20.4% is below the industry leading edge
  • No high-power panels (500W+) available for commercial use
  • Limited adoption of latest cell technologies (TOPCon/HJT)
