Compare Tongwei panels on ComparePV." source: "https://comparepv.com/reviews/tongwei" --- # Tongwei panels, *read off the datasheets* Tongwei has 122 modules in the database, from 400 to 750 Wp. Everything below is computed from those 122 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Tongwei does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2013 - **Headquarters:** Chengdu, China - **Listed:** SSE: 600438 - **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 | 122 | models in the database | | Average efficiency | 22.6 % | across the catalogue | | Best efficiency | 24.2 % (good) | their strongest module | | Power range | 400-750 Wp | smallest to largest | | Bifacial share | 69 % | 84 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Tongwei'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 | [TWMNH-66HD655](https://comparepv.com/panel/tongwei-solar-twmnh-66hd655) | 655 Wp | 24.2% (good) | | 2 | [TWMNF-66HD750](https://comparepv.com/panel/tongwei-solar-twmnf-66hd750) | 750 Wp | 24.1% (good) | | 3 | [TWMNH-66HD650](https://comparepv.com/panel/tongwei-solar-twmnh-66hd650) | 650 Wp | 24.1% (good) | | 4 | [TWMNF-66HD745](https://comparepv.com/panel/tongwei-solar-twmnf-66hd745) | 745 Wp | 24.0% (good) | | 5 | [TWMNH-66HD645](https://comparepv.com/panel/tongwei-solar-twmnh-66hd645) | 645 Wp | 23.9% (good) | - TWMNH-66HD655 - Monocrystalline bifacial - TWMNF-66HD750 - Monocrystalline bifacial - TWMNH-66HD650 - Monocrystalline bifacial - TWMNF-66HD745 - Monocrystalline bifacial - TWMNH-66HD645 - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/tongwei?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [TWMNF-66HD750](https://comparepv.com/panel/tongwei-solar-twmnf-66hd750) | 24.1% (good) | 750 Wp | | 2 | [TWMNF-66HD745](https://comparepv.com/panel/tongwei-solar-twmnf-66hd745) | 24.0% (good) | 745 Wp | | 3 | [TWMNF-66HD740](https://comparepv.com/panel/tongwei-solar-twmnf-66hd740) | 23.8% (good) | 740 Wp | | 4 | [TWMHF-66HD740X](https://comparepv.com/panel/tw-solar-twmhf-66hd740x) | 23.8% (good) | 740 Wp | | 5 | [THC G12-66 Bifacial](https://comparepv.com/panel/tongwei-thc-g12-66-bifacial) | 23.8% (good) | 740 Wp | - TWMNF-66HD750 - Monocrystalline bifacial - TWMNF-66HD745 - Monocrystalline bifacial - TWMNF-66HD740 - Monocrystalline bifacial - TWMHF-66HD740X - Monocrystalline bifacial - THC G12-66 Bifacial - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/tongwei?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 122 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.
