Compare Bauer Solar panels on ComparePV." source: "https://comparepv.com/reviews/bauer-solar" --- # Bauer Solar panels, *read off the datasheets* Bauer Solar has 6 modules in the database, from 440 to 475 Wp. Everything below is computed from those 6 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Bauer Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Headquarters:** 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 | 6 | models in the database | | Average efficiency | 22.0 % | across the catalogue | | Best efficiency | 22.5 % | their strongest module | | Power range | 440-475 Wp | smallest to largest | | Bifacial share | 100 % | 6 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Bauer 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. ### Most efficient module efficiency | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [BS-450-108M10HBT-GG](https://comparepv.com/panel/bauer-solar-bs-450-108m10hbt-gg) | 450 Wp | 22.5% (good) | | 2 | [BS-445-108M10HBT-GG](https://comparepv.com/panel/bauer-solar-bs-445-108m10hbt-gg) | 445 Wp | 22.3% (good) | | 3 | [BS-440-108M10HBT-GG](https://comparepv.com/panel/bauer-solar-bs-440-108m10hbt-gg) | 440 Wp | 22.0% (good) | | 4 | [BS-475-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-475-120m10nhbb-gg) | 475 Wp | 21.9% | | 5 | [BS-470-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-470-120m10nhbb-gg) | 470 Wp | 21.7% | - BS-450-108M10HBT-GG - Monocrystalline bifacial - BS-445-108M10HBT-GG - Monocrystalline bifacial - BS-440-108M10HBT-GG - Monocrystalline bifacial - BS-475-120M10NHBB-GG - Monocrystalline bifacial - BS-470-120M10NHBB-GG - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/bauer-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [BS-475-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-475-120m10nhbb-gg) | 21.9% | 475 Wp | | 2 | [BS-470-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-470-120m10nhbb-gg) | 21.7% | 470 Wp | | 3 | [BS-465-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-465-120m10nhbb-gg) | 21.5% | 465 Wp | | 4 | [BS-450-108M10HBT-GG](https://comparepv.com/panel/bauer-solar-bs-450-108m10hbt-gg) | 22.5% (good) | 450 Wp | | 5 | [BS-445-108M10HBT-GG](https://comparepv.com/panel/bauer-solar-bs-445-108m10hbt-gg) | 22.3% (good) | 445 Wp | - BS-475-120M10NHBB-GG - Monocrystalline bifacial - BS-470-120M10NHBB-GG - Monocrystalline bifacial - BS-465-120M10NHBB-GG - Monocrystalline bifacial - BS-450-108M10HBT-GG - Monocrystalline bifacial - BS-445-108M10HBT-GG - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/bauer-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 6 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.
