Compare Hounen Solar panels on ComparePV." source: "https://comparepv.com/reviews/hounen-solar" --- # Hounen Solar panels, *read off the datasheets* Hounen Solar (Zhejiang Haoneng Optoelectronics) is a Chinese solar PV module manufacturer with its U.S. operations branded as Hounen Solar America. The company produces solar panels for residential, commercial, and utility-scale applications, and in 2023 established a 1 GW module assembly facility... 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 Hounen Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2010 - **Headquarters:** Haining, China - **Annual capacity:** 1-2 GW - **Employees:** 200-500 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 | 21.7 % | across the catalogue | | Best efficiency | 23.3 % (good) | their strongest module | | Power range | 395-725 Wp | smallest to largest | | Bifacial share | 86 % | 38 dual-sided models | | Average warranty | 29 years | guaranteed output term | ## 01. The top of the range The leaders of Hounen 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 | [HNM8-GPLDD132-725/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-725-n) | 725 Wp | 23.3% (good) | | 2 | [HNM8-GPLDD132-720/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-720-n) | 720 Wp | 23.2% (good) | | 3 | [HNM8-GPLDD132-715/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-715-n) | 715 Wp | 23.0% (good) | | 4 | [HNM8-GPLDD132-710/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-710-n) | 710 Wp | 22.9% (good) | | 5 | [HNM8-GPLDD132-705/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-705-n) | 705 Wp | 22.7% (good) | - HNM8-GPLDD132-725/N - Monocrystalline bifacial - HNM8-GPLDD132-720/N - Monocrystalline bifacial - HNM8-GPLDD132-715/N - Monocrystalline bifacial - HNM8-GPLDD132-710/N - Monocrystalline bifacial - HNM8-GPLDD132-705/N - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/hounen-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [HNM8-GPLDD132-725/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-725-n) | 23.3% (good) | 725 Wp | | 2 | [HNM8-GPLDD132-720/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-720-n) | 23.2% (good) | 720 Wp | | 3 | [HNM8-GPLDD132-715/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-715-n) | 23.0% (good) | 715 Wp | | 4 | [HNM8-GPLDD132-710/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-710-n) | 22.9% (good) | 710 Wp | | 5 | [HNM8-GPLDD132-705/N](https://comparepv.com/panel/hounen-solar-hnm8-gpldd132-705-n) | 22.7% (good) | 705 Wp | - HNM8-GPLDD132-725/N - Monocrystalline bifacial - HNM8-GPLDD132-720/N - Monocrystalline bifacial - HNM8-GPLDD132-715/N - Monocrystalline bifacial - HNM8-GPLDD132-710/N - Monocrystalline bifacial - HNM8-GPLDD132-705/N - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/hounen-solar?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.
