Leapton panels, read off the datasheets

Leapton Energy, headquartered in Japan, is a global leader in the solar PV industry, specializing in Tier-1 solar modules, battery energy storage systems (BESS), and inverters. With over 10 years of experience, Leapton Energy's products are now available in more than 70...

Everything below is computed from those 119 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Leapton does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of Leapton'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

Cell technology across the market

Shares are of the 119 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 accounts for 88.2% of the catalogue - 105 of 119 modules.
