Compare Resun Solar panels on ComparePV." source: "https://comparepv.com/reviews/resun-solar" --- # Resun Solar panels, *read off the datasheets* Resun Solar Energy Co., Ltd. specializes in developing and manufacturing high-quality, cost-effective photovoltaic solar modules. With factories accredited by ISO9001 & 14001, their panels are certified by TUV, IEC61215, IEC61730, and other international quality systems. The company's sales network spans over 80... Everything below is computed from those 236 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Resun Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2007 - **Headquarters:** Suzhou, China - **Annual capacity:** 1 GW 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 | 236 | models in the database | | Average efficiency | 21.5 % | across the catalogue | | Best efficiency | 23.7 % (good) | their strongest module | | Power range | 60-735 Wp | smallest to largest | | Bifacial share | 31 % | 73 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Resun 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 | [RS9H-M TOPCON-735](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-735) | 735 Wp | 23.7% (good) | | 2 | [RS9H-M TOPCON-730](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-730) | 730 Wp | 23.5% (good) | | 3 | [RS9H-M TOPCON-725](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-725) | 725 Wp | 23.3% (good) | | 4 | [RS8H-M-630](https://comparepv.com/panel/resun-solar-rs8h-m-630) | 630 Wp | 23.3% (good) | | 5 | [RS8I-M-BD TOPCON](https://comparepv.com/panel/resun-solar-rs8i-m-bd-topcon) | 630 Wp | 23.3% (good) | - RS9H-M TOPCON-735 - Monocrystalline - RS9H-M TOPCON-730 - Monocrystalline - RS9H-M TOPCON-725 - Monocrystalline - RS8H-M-630 - Monocrystalline - RS8I-M-BD TOPCON - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/resun-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [RS9H-M TOPCON-735](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-735) | 23.7% (good) | 735 Wp | | 2 | [RS9H-M TOPCON-730](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-730) | 23.5% (good) | 730 Wp | | 3 | [RS9H-M TOPCON-725](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-725) | 23.3% (good) | 725 Wp | | 4 | [RS9H-M TOPCON-720](https://comparepv.com/panel/resun-solar-rs9h-m-topcon-720) | 23.2% (good) | 720 Wp | | 5 | [RS9H-M-720](https://comparepv.com/panel/resun-solar-rs9h-m-720) | 23.2% (good) | 720 Wp | - RS9H-M TOPCON-735 - Monocrystalline - RS9H-M TOPCON-730 - Monocrystalline - RS9H-M TOPCON-725 - Monocrystalline - RS9H-M TOPCON-720 - Monocrystalline - RS9H-M-720 - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/resun-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 236 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. [Cell technology across the market](https://comparepv.com/stats/cell-technology) ### Cell technology share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | TOPCon | 65.7% | 155 | | | Unknown | 34.3% | 81 | TOPCon accounts for 65.7% of the catalogue - 155 of 236 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 11.9% | 28 | | | 20-21% | 12.7% | 30 | | | 21-22% | 25.4% | 60 | | | 22-23% | 42.8% | 101 | | | 23%+ | 7.2% | 17 | ## 04.
