Compare Solarwatt panels on ComparePV." source: "https://comparepv.com/reviews/solarwatt" --- # Solarwatt panels, *read off the datasheets* Solarwatt has 44 modules in the database, from 180 to 460 Wp. Everything below is computed from those 44 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Solarwatt does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 1993 - **Headquarters:** Dresden, Germany 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 | 44 | models in the database | | Average efficiency | 20.6 % | across the catalogue | | Best efficiency | 23.0 % (good) | their strongest module | | Power range | 180-460 Wp | smallest to largest | | Bifacial share | 50 % | 22 dual-sided models | | Average warranty | 29 years | guaranteed output term | ## 01. The top of the range The leaders of Solarwatt'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 | [SOLARWATT Panel vision M 5.0 460 Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-460-wp) | 460 Wp | 23.0% (good) | | 2 | [SOLARWATT Panel vision M 5.0 455 Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-455-wp) | 455 Wp | 22.8% (good) | | 3 | [SOLARWATT Panel vision M 5.0 450 Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-450-wp) | 450 Wp | 22.5% (good) | | 4 | [SOLARWATT Panel vision M 5.0 450Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-450wp) | 450 Wp | 22.5% (good) | | 5 | [vision M 5.0 450 Wp](https://comparepv.com/panel/solarwatt-vision-m-5-0-450-wp) | 450 Wp | 22.5% (good) | - SOLARWATT Panel vision M 5.0 460 Wp - Monocrystalline bifacial - SOLARWATT Panel vision M 5.0 455 Wp - Monocrystalline bifacial - SOLARWATT Panel vision M 5.0 450 Wp - Monocrystalline bifacial - SOLARWATT Panel vision M 5.0 450Wp - Monocrystalline bifacial - vision M 5.0 450 Wp - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/solarwatt?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [SOLARWATT Panel vision M 5.0 460 Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-460-wp) | 23.0% (good) | 460 Wp | | 2 | [SOLARWATT Panel vision M 5.0 455 Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-455-wp) | 22.8% (good) | 455 Wp | | 3 | [SOLARWATT Panel vision M 5.0 450 Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-450-wp) | 22.5% (good) | 450 Wp | | 4 | [SOLARWATT Panel vision M 5.0 450Wp](https://comparepv.com/panel/solarwatt-solarwatt-panel-vision-m-5-0-450wp) | 22.5% (good) | 450 Wp | | 5 | [vision M 5.0 450 Wp](https://comparepv.com/panel/solarwatt-vision-m-5-0-450-wp) | 22.5% (good) | 450 Wp | - SOLARWATT Panel vision M 5.0 460 Wp - Monocrystalline bifacial - SOLARWATT Panel vision M 5.0 455 Wp - Monocrystalline bifacial - SOLARWATT Panel vision M 5.0 450 Wp - Monocrystalline bifacial - SOLARWATT Panel vision M 5.0 450Wp - Monocrystalline bifacial - vision M 5.0 450 Wp - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/solarwatt?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 44 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.
