Compare Haitai Solar panels on ComparePV." source: "https://comparepv.com/reviews/haitai-solar" --- # Haitai Solar panels, *read off the datasheets* Haitai Solar, founded in 2006, is a high-tech enterprise focused on green energy, covering nine major business segments including PV modules, PV power stations, PV mounting systems, energy storage, hydrogen energy, wind energy, PV cells, graphite/Carbon electrodes, and battery swapping. The company... Everything below is computed from those 16 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Haitai Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2006 - **Headquarters:** Tangshan, China - **Annual capacity:** 10 GW - **Employees:** 1001-5000 - **Listed:** Beijing Stock Exchange: 920985 - **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 | 16 | models in the database | | Average efficiency | 21.7 % | across the catalogue | | Best efficiency | 23.2 % (good) | their strongest module | | Power range | 310-720 Wp | smallest to largest | | Bifacial share | 100 % | 16 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Haitai 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 | [JT720SLkB](https://comparepv.com/panel/haitai-solar-jt720slkb) | 720 Wp | 23.2% (good) | | 2 | [JT715SLkB](https://comparepv.com/panel/haitai-solar-jt715slkb) | 715 Wp | 23.0% (good) | | 3 | [JT710SLkB](https://comparepv.com/panel/haitai-solar-jt710slkb) | 710 Wp | 22.9% (good) | | 4 | [CETC-455TR(GDF)/96](https://comparepv.com/panel/haitai-solar-cetc-455tr-gdf-96) | 455 Wp | 22.8% (good) | | 5 | [JT705SLkB](https://comparepv.com/panel/haitai-solar-jt705slkb) | 705 Wp | 22.7% (good) | - JT720SLkB - Monocrystalline bifacial - JT715SLkB - Monocrystalline bifacial - JT710SLkB - Monocrystalline bifacial - CETC-455TR(GDF)/96 - Monocrystalline bifacial - JT705SLkB - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/haitai-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [JT720SLkB](https://comparepv.com/panel/haitai-solar-jt720slkb) | 23.2% (good) | 720 Wp | | 2 | [JT715SLkB](https://comparepv.com/panel/haitai-solar-jt715slkb) | 23.0% (good) | 715 Wp | | 3 | [JT710SLkB](https://comparepv.com/panel/haitai-solar-jt710slkb) | 22.9% (good) | 710 Wp | | 4 | [JT705SLkB](https://comparepv.com/panel/haitai-solar-jt705slkb) | 22.7% (good) | 705 Wp | | 5 | [JT700SLkB](https://comparepv.com/panel/haitai-solar-jt700slkb) | 22.5% (good) | 700 Wp | - JT720SLkB - Monocrystalline bifacial - JT715SLkB - Monocrystalline bifacial - JT710SLkB - Monocrystalline bifacial - JT705SLkB - Monocrystalline bifacial - JT700SLkB - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/haitai-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 16 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 | 56.3% | 9 | | | HJT | 43.8% | 7 | TOPCon accounts for 56.3% of the catalogue - 9 of 16 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 25.0% | 4 | | | 21-22% | 6.3% | 1 | | | 22-23% | 56.3% | 9 | | | 23%+ | 12.5% | 2 | ## 04.
