Compare Sonnex Energie panels on ComparePV." source: "https://comparepv.com/reviews/sonnex-energie" --- # Sonnex Energie panels, *read off the datasheets* Sonnex Energie has 10 modules in the database, from 415 to 440 Wp. Everything below is computed from those 10 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Sonnex Energie does not publish a figure, it is left out of the average rather than assumed. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 10 | models in the database | | Average efficiency | 21.9 % | across the catalogue | | Best efficiency | 22.5 % | their strongest module | | Power range | 415-440 Wp | smallest to largest | | Bifacial share | 50 % | 5 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Sonnex Energie'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 | [SNX-D54HN\*\*\*-M-S (440W)](https://comparepv.com/panel/sonnex-energie-snx-d54hn-m-s-440w) | 440 Wp | 22.5% (good) | | 2 | [SNX-D54HN\*\*\*-M-S (435W)](https://comparepv.com/panel/sonnex-energie-snx-d54hn-m-s-435w) | 435 Wp | 22.3% (good) | | 3 | [SNX-D54HND-435M](https://comparepv.com/panel/sonnex-energie-snx-d54hnd-435m) | 435 Wp | 22.3% (good) | | 4 | [SNX-D54HND-430M](https://comparepv.com/panel/sonnex-energie-snx-d54hnd-430m) | 430 Wp | 22.0% (good) | | 5 | [SNX-D54HN\*\*\*-M-S (430W)](https://comparepv.com/panel/sonnex-energie-snx-d54hn-m-s-430w) | 430 Wp | 22.0% (good) | - SNX-D54HN\*\*\*-M-S (440W) - Monocrystalline - SNX-D54HN\*\*\*-M-S (435W) - Monocrystalline - SNX-D54HND-435M - Monocrystalline bifacial - SNX-D54HND-430M - Monocrystalline bifacial - SNX-D54HN\*\*\*-M-S (430W) - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/sonnex-energie?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [SNX-D54HN\*\*\*-M-S (440W)](https://comparepv.com/panel/sonnex-energie-snx-d54hn-m-s-440w) | 22.5% (good) | 440 Wp | | 2 | [SNX-D54HN\*\*\*-M-S (435W)](https://comparepv.com/panel/sonnex-energie-snx-d54hn-m-s-435w) | 22.3% (good) | 435 Wp | | 3 | [SNX-D54HND-435M](https://comparepv.com/panel/sonnex-energie-snx-d54hnd-435m) | 22.3% (good) | 435 Wp | | 4 | [SNX-D54HN\*\*\*-M-S (430W)](https://comparepv.com/panel/sonnex-energie-snx-d54hn-m-s-430w) | 22.0% (good) | 430 Wp | | 5 | [SNX-D54HND-430M](https://comparepv.com/panel/sonnex-energie-snx-d54hnd-430m) | 22.0% (good) | 430 Wp | - SNX-D54HN\*\*\*-M-S (440W) - Monocrystalline - SNX-D54HN\*\*\*-M-S (435W) - Monocrystalline - SNX-D54HND-435M - Monocrystalline bifacial - SNX-D54HN\*\*\*-M-S (430W) - Monocrystalline - SNX-D54HND-430M - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/sonnex-energie?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 10 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 across the market](https://comparepv.com/stats/cell-technology) ### Cell technology share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | TOPCon | 100.0% | 10 | TOPCon accounts for 100.0% of the catalogue - 10 of 10 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | 21-22% | 50.0% | 5 | | | 22-23% | 50.0% | 5 | ## 04.
