Compare Canadian Solar panels on ComparePV." source: "https://comparepv.com/reviews/canadian-solar" --- # Canadian Solar panels, *read off the datasheets* Canadian Solar Inc. is a global renewable energy company founded in 2001. Headquartered in Kitchener, Ontario, it manufactures solar PV modules and provides battery energy storage solutions. The company also develops utility-scale solar power and battery energy storage projects. Everything below is computed from those 292 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Canadian Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2001 - **Headquarters:** Kitchener, Canada - **Annual capacity:** 51 GW - **Employees:** 17,113 - **Listed:** NASDAQ: CSIQ - **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 | 292 | models in the database | | Average efficiency | 20.7 % | across the catalogue | | Best efficiency | 24.4 % (good) | their strongest module | | Power range | 290-730 Wp | smallest to largest | | Bifacial share | 46 % | 133 dual-sided models | | Average warranty | 28 years | guaranteed output term | ## 01. The top of the range The leaders of Canadian 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 | [CS6.2-66TB-660](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-660) | 660 Wp | 24.4% (good) | | 2 | [CS6.2-66TB-655](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-655) | 655 Wp | 24.2% (good) | | 3 | [CS6.2-66TB-650](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-650) | 650 Wp | 24.1% (good) | | 4 | [CS6.2-66HB-645](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-645) | 645 Wp | 23.9% (good) | | 5 | [CS6.2-66TB-645](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-645) | 645 Wp | 23.9% (good) | - CS6.2-66TB-660 - Monocrystalline bifacial - CS6.2-66TB-655 - Monocrystalline bifacial - CS6.2-66TB-650 - Monocrystalline bifacial - CS6.2-66HB-645 - Monocrystalline bifacial - CS6.2-66TB-645 - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/canadian-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [CS7N-730TB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-730tb-ag) | 23.5% (good) | 730 Wp | | 2 | [CS7N-725TB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-725tb-ag) | 23.3% (good) | 725 Wp | | 3 | [CS7N-720TB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-720tb-ag) | 23.2% (good) | 720 Wp | | 4 | [CS7N-715TB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-715tb-ag) | 23.0% (good) | 715 Wp | | 5 | [CS7N-710TB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-710tb-ag) | 22.9% (good) | 710 Wp | - CS7N-730TB-AG - Monocrystalline bifacial - CS7N-725TB-AG - Monocrystalline bifacial - CS7N-720TB-AG - Monocrystalline bifacial - CS7N-715TB-AG - Monocrystalline bifacial - CS7N-710TB-AG - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/canadian-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 292 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 | | --- | --- | --- | --- | | | PERC | 66.8% | 195 | | | TOPCon | 29.1% | 85 | | | HJT | 4.1% | 12 | PERC accounts for 66.8% of the catalogue - 195 of 292 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 43.8% | 128 | | | 20-21% | 12.3% | 36 | | | 21-22% | 14.0% | 41 | | | 22-23% | 17.1% | 50 | | | 23%+ | 12.7% | 37 | ## 04. Strengths and gaps Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built. ### What this catalogue is good at - **Strength:** Extensive portfolio of 292 panels across multiple series - **Strength:** Tier 1 bankable manufacturer - recognized by major financial institutions - **Strength:** High-efficiency panels available (up to 24.4%) - **Strength:** Strong warranty coverage averaging 28 years - **Strength:** High-power panels available (up to 730W) for commercial applications - **Strength:** Established manufacturer with 25+ years of experience - **Strength:** Large-scale production capacity of 51 GW ### Where it is thin - **Watch out:** Average efficiency of 20.7% is below the industry leading edge ## 05.
