Techwise Solar panels, read off the datasheets

Techwise Solar has 164 modules in the database, from 150 to 720 Wp.

Everything below is computed from those 164 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Techwise Solar does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of Techwise 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 TW-450HT-06 Monocrystalline bifacial 450 Wp 23.0% 2 TW-450HTS-06 Monocrystalline 450 Wp 23.0% 3 TW-445HT-06 Monocrystalline bifacial 445 Wp 22.8% 4 TW-445HTS-06 Monocrystalline 445 Wp 22.8% 5 TW-455HDB-1 Monocrystalline bifacial 455 Wp 22.8%

What the catalogue is made of

Cell technology across the market

Shares are of the 164 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 69.5% 114 PERC 28.0% 46 Unknown 2.4% 4
TOPCon accounts for 69.5% of the catalogue - 114 of 164 modules.
