Compare HD Solar panels on ComparePV." source: "https://comparepv.com/reviews/hd-solar" --- # HD Solar panels, *read off the datasheets* HD Solar has 7 modules in the database, from 605 to 635 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 HD Solar does not publish a figure, it is left out of the average rather than assumed. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 7 | models in the database | | Average efficiency | 23.0 % | across the catalogue | | Best efficiency | 23.5 % (good) | their strongest module | | Power range | 605-635 Wp | smallest to largest | | Bifacial share | 100 % | 7 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of HD 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 | [HD-N-G12-635](https://comparepv.com/panel/hd-solar-hd-n-g12-635) | 635 Wp | 23.5% (good) | | 2 | [HD-N-G12-630](https://comparepv.com/panel/hd-solar-hd-n-g12-630) | 630 Wp | 23.3% (good) | | 3 | [HD-N-G12-625](https://comparepv.com/panel/hd-solar-hd-n-g12-625) | 625 Wp | 23.1% (good) | | 4 | [HD-N-G12-620](https://comparepv.com/panel/hd-solar-hd-n-g12-620) | 620 Wp | 23.0% (good) | | 5 | [HD-N-G12-615](https://comparepv.com/panel/hd-solar-hd-n-g12-615) | 615 Wp | 22.8% (good) | - HD-N-G12-635 - Monocrystalline bifacial - HD-N-G12-630 - Monocrystalline bifacial - HD-N-G12-625 - Monocrystalline bifacial - HD-N-G12-620 - Monocrystalline bifacial - HD-N-G12-615 - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/hd-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [HD-N-G12-635](https://comparepv.com/panel/hd-solar-hd-n-g12-635) | 23.5% (good) | 635 Wp | | 2 | [HD-N-G12-630](https://comparepv.com/panel/hd-solar-hd-n-g12-630) | 23.3% (good) | 630 Wp | | 3 | [HD-N-G12-625](https://comparepv.com/panel/hd-solar-hd-n-g12-625) | 23.1% (good) | 625 Wp | | 4 | [HD-N-G12-620](https://comparepv.com/panel/hd-solar-hd-n-g12-620) | 23.0% (good) | 620 Wp | | 5 | [HD-N-G12-615](https://comparepv.com/panel/hd-solar-hd-n-g12-615) | 22.8% (good) | 615 Wp | - HD-N-G12-635 - Monocrystalline bifacial - HD-N-G12-630 - Monocrystalline bifacial - HD-N-G12-625 - Monocrystalline bifacial - HD-N-G12-620 - Monocrystalline bifacial - HD-N-G12-615 - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/hd-solar?sort_by=power&sort_order=desc) ## 02.

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.
