Compare TommaTech panels on ComparePV." source: "https://comparepv.com/reviews/tommatech" --- # TommaTech panels, *read off the datasheets* TommaTech has 7 modules in the database, from 570 to 600 Wp. Everything below is computed from those 7 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where TommaTech does not publish a figure, it is left out of the average rather than assumed. ## The company - **Headquarters:** Istanbul, Turkey Company facts, not datasheet figures. Tier 1 is a financier's bankability list, and says nothing about how a panel performs. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 7 | models in the database | | Average efficiency | 22.6 % | across the catalogue | | Best efficiency | 23.2 % (good) | their strongest module | | Power range | 570-600 Wp | smallest to largest | | Bifacial share | 0 % | 0 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of TommaTech'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. ### Most efficient module efficiency | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [TT600-144TN10](https://comparepv.com/panel/tommatech-tt600-144tn10) | 600 Wp | 23.2% (good) | | 2 | [TT595-144TN10](https://comparepv.com/panel/tommatech-tt595-144tn10) | 595 Wp | 23.0% (good) | | 3 | [TT590-144TN10](https://comparepv.com/panel/tommatech-tt590-144tn10) | 590 Wp | 22.8% (good) | | 4 | [TT585-144TN10](https://comparepv.com/panel/tommatech-tt585-144tn10) | 585 Wp | 22.6% (good) | | 5 | [TT580-144TN10](https://comparepv.com/panel/tommatech-tt580-144tn10) | 580 Wp | 22.4% (good) | - TT600-144TN10 - Monocrystalline - TT595-144TN10 - Monocrystalline - TT590-144TN10 - Monocrystalline - TT585-144TN10 - Monocrystalline - TT580-144TN10 - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/tommatech?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [TT600-144TN10](https://comparepv.com/panel/tommatech-tt600-144tn10) | 23.2% (good) | 600 Wp | | 2 | [TT595-144TN10](https://comparepv.com/panel/tommatech-tt595-144tn10) | 23.0% (good) | 595 Wp | | 3 | [TT590-144TN10](https://comparepv.com/panel/tommatech-tt590-144tn10) | 22.8% (good) | 590 Wp | | 4 | [TT585-144TN10](https://comparepv.com/panel/tommatech-tt585-144tn10) | 22.6% (good) | 585 Wp | | 5 | [TT580-144TN10](https://comparepv.com/panel/tommatech-tt580-144tn10) | 22.4% (good) | 580 Wp | - TT600-144TN10 - Monocrystalline - TT595-144TN10 - Monocrystalline - TT590-144TN10 - Monocrystalline - TT585-144TN10 - Monocrystalline - TT580-144TN10 - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/tommatech?sort_by=power&sort_order=desc) ## 02. By what the array is for Three cuts of the same catalogue, each ordered by efficiency inside its band.

What the catalogue is made of Shares are of the 7 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.
