BYD panels, read off the datasheets

BYD has 115 modules in the database, from 380 to 735 Wp.

Everything below is computed from those 115 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where BYD does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of BYD'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 NLBK-27-450 Monocrystalline bifacial 450 Wp 23.0% 2 NLK-27-450W Monocrystalline 450 Wp 23.0% 3 NLBK-27-445 Monocrystalline bifacial 445 Wp 22.8% 4 NLK-27-445W Monocrystalline 445 Wp 22.8% 5 NLTK-27-445W Monocrystalline bifacial 445 Wp 22.8%

What the catalogue is made of

Cell technology across the market

Shares are of the 115 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
TOPCon 62.6% 72 PERC 26.1% 30 HJT 11.3% 13
TOPCon accounts for 62.6% of the catalogue - 72 of 115 modules.
