Compare DAH Solar panels on ComparePV." source: "https://comparepv.com/reviews/dah-solar" --- # DAH Solar panels, *read off the datasheets* DAH Solar is an innovation-driven and technology-leading company specializing in PV product manufacturing. They focus on R&D, manufacturing, and sales of high-efficiency PV modules, integrated PV systems, and solar energy storage systems. DAH Solar is known for its patented Full-Screen PV Module... Everything below is computed from those 363 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where DAH Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2009 - **Headquarters:** Hefei, China - **Annual capacity:** 10 GW - **Employees:** 2000+ - **Tier 1 bankable:** Yes (good) 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 | 363 | models in the database | | Average efficiency | 22.1 % | across the catalogue | | Best efficiency | 23.3 % (good) | their strongest module | | Power range | 380-725 Wp | smallest to largest | | Bifacial share | 87 % | 316 dual-sided models | | Average warranty | 29 years | guaranteed output term | ## 01. The top of the range The leaders of DAH 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 | [DHN-66Y18/DG-725](https://comparepv.com/panel/dah-dhn-66y18-dg-725) | 725 Wp | 23.3% (good) | | 2 | [DHN-54R20/DG-465](https://comparepv.com/panel/dah-dhn-54r20-dg-465) | 465 Wp | 23.3% (good) | | 3 | [DHN-54R20/DG(BW) 465W](https://comparepv.com/panel/dah-dhn-54r20-dg-bw-465w) | 465 Wp | 23.3% (good) | | 4 | [DHN-54R20/DG(BW)-465](https://comparepv.com/panel/dah-dhn-54r20-dg-bw-465) | 465 Wp | 23.3% (good) | | 5 | [DHN-66Y18/DG-720](https://comparepv.com/panel/dah-dhn-66y18-dg-720) | 720 Wp | 23.2% (good) | - DHN-66Y18/DG-725 - Monocrystalline bifacial - DHN-54R20/DG-465 - Monocrystalline bifacial - DHN-54R20/DG(BW) 465W - Monocrystalline bifacial - DHN-54R20/DG(BW)-465 - Monocrystalline bifacial - DHN-66Y18/DG-720 - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/dah-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [DHN-66Y18/DG-725](https://comparepv.com/panel/dah-dhn-66y18-dg-725) | 23.3% (good) | 725 Wp | | 2 | [DHN-66Y18/DG-720](https://comparepv.com/panel/dah-dhn-66y18-dg-720) | 23.2% (good) | 720 Wp | | 3 | [DHN-66Y18/DG-715](https://comparepv.com/panel/dah-dhn-66y18-dg-715) | 23.0% (good) | 715 Wp | | 4 | [DAS-DH132NC-715](https://comparepv.com/panel/dah-solar-das-dh132nc-715) | 23.0% (good) | 715 Wp | | 5 | [DHN-66Y18/DG-710](https://comparepv.com/panel/dah-dhn-66y18-dg-710) | 22.9% (good) | 710 Wp | - DHN-66Y18/DG-725 - Monocrystalline bifacial - DHN-66Y18/DG-720 - Monocrystalline bifacial - DHN-66Y18/DG-715 - Monocrystalline bifacial - DAS-DH132NC-715 - Monocrystalline bifacial - DHN-66Y18/DG-710 - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/dah-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 363 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.
