On a summer day with a module temperature of 65°C, this translates into measurably higher hourly energy yield relative to the previous generation of technology. - **Maximum Degradation of 0.4%/Year Over 30 Years** - The 30-year linear power warranty with an annual degradation cap of 0.4% (after Year 1) outperforms the typical 25-year/0.55% warranty standard for PERC modules. DNV's factory audit report for Canadian Solar recommends an assumed useful service life of 35–45 years for TOPBiHiKu7 modules — a notable bankability signal. - **Bifaciality Up to 85% — Tangible Energy Yield Gain** - The rated bifaciality factor reaches up to 85%. With a ground albedo of 0.35 (light gravel, concrete) and adequate row clearance, this delivers a real energy gain of 8–15% over an equivalent monofacial module, directly reducing LCOE in ground-mount utility projects and carport installations. - **LID/LeTID Resistance Confirmed by Testing** - N-type TOPCon cells exhibit approximately 1.0% degradation in H1 damp-heat testing (2,000 h), versus ~1.9% for P-type PERC. The elimination of boron-induced LID is inherent to N-type cell technology, reducing the risk of early power loss following system commissioning. - **BNEF Tier-1, DNV Audit, Bankability Q1 2026** - Canadian Solar maintains BNEF Tier-1 status in Q1 2026 and holds an independent DNV technology report. For non-recourse debt-financed projects, this is a key prerequisite — modules are accepted by major project finance banks without additional product-level due diligence. ## Cons - **Weight ~37.8 kg — Constraint for Rooftop Installations** - G12R-format modules in this series weigh approximately 37.8 kg, requiring a two-person installation crew and a structural assessment of the roof's load-bearing capacity. For prosumer installations on older buildings, this may rule out the series in favor of lighter alternatives (e.g., 400–450 W modules at ~21–23 kg). ## About this series The Canadian Solar TOPBiHiKu7 series was designed with installations in mind where maximizing yield from the same surface area and better overall system economics are key. These modules are based on **TOPCon N-type cells**, which maintain efficiency better over time and are less prone to typical degradation-accelerating phenomena. The key advantage is the **bifacial design** - the panel actively generates electricity not only from the front side but also the rear, significantly boosting energy production when mounted on suitable surfaces and frame structures. The TOPBiHiKu7 also boasts a **low temperature coefficient**, helping stabilize energy output during warmer periods and narrowing the gap between theoretical performance and real-world operation. In practice, this translates to a **lower energy and BOS cost** - fewer modules and auxiliary components for the same project capacity, plus faster installation on farms. This series is primarily aimed at utility-scale PV farms, C&I projects, large rooftops, carports, and any application where durability and predictable energy production are crucial. Compared to many PERC modules, TOPBiHiKu7 focuses on higher yields and greater resilience against performance degradation over the long term. ## Notable figures - Efficiency of 23.3% matches the \*\*TOPCon 700-750W\*\* median - At 233.4 W/m² power density, this panel generates 3.2 W/m² more per unit area than \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 700-750W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - #1017 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty does the Canadian Solar TOPBiHiKu7 series carry? The TOPBiHiKu7 series comes with a 12-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty. Under the power warranty, the manufacturer guarantees that degradation will not exceed 1% in the first year and no more than 0.4% per year in subsequent years. As a Tier 1 manufacturer with a global service network, Canadian Solar provides genuine assurance that these commitments can be enforced. ### What does the bifacial design of the TOPBiHiKu7 offer, and when does it pay off? Thanks to its dual-sided operation, the TOPBiHiKu7 module captures light from both the front side and light reflected off the ground or surroundings through the rear glass, achieving a bifaciality factor of up to 85%. The greatest energy yield gains are realized in utility-scale PV plants with high-albedo ground surfaces (light-colored gravel, concrete, or snow) or in elevated mounting configurations such as canopies and carports. In typical ground-mount farm installations, the yield increase ranges from several to over ten percent compared to monofacial modules. ### Are the Canadian Solar TOPBiHiKu7 730W panels suitable for installation on a warehouse or industrial hall roof? Yes, but this requires a structural assessment of the roof. The TOPBiHiKu7 730W module measures 2384×1303×33 mm and weighs 37.8 kg, which generates significant roof loading in large commercial and industrial (C&I) installations. The module is rated to withstand snow loads of up to 5400 Pa and wind loads of up to 2400 Pa, so its mechanical parameters are robust. Prior to installation on an industrial facility, a structural engineering assessment of the roof and proper selection of racking and mounting systems are required. ### How does TOPCon cell technology in the TOPBiHiKu7 series differ from older PERC cells? The N-type TOPCon cells in the TOPBiHiKu7 achieve a module efficiency of up to 23.5%, significantly higher than typical PERC modules, which generally fall in the 20–22% range. A key differentiator is the lower temperature coefficient of −0.29%/°C compared to approximately −0.35%/°C for PERC, resulting in reduced power losses on hot days. TOPCon technology is also substantially more resistant to LID (Light-Induced Degradation) and LeTID (Light and elevated Temperature-Induced Degradation) phenomena, which accelerate degradation in PERC modules during the first years of operation. ### How many TOPBiHiKu7 modules do I need for a 1 MW solar farm? With the 730W variant, approximately 1,370 modules are sufficient for 1 MW of installed capacity. This is roughly ten to fifteen percent fewer units than a typical 600 W PERC-class module would require, which directly reduces balance-of-system (BoS) costs: fewer mounting structures, less cabling, and faster installation. In large-scale PV farm projects, this difference can significantly improve the overall investment economics and shorten the project completion timeline. ### How well do the TOPBiHiKu7 panels perform at high temperatures during summer? The TOPBiHiKu7 series features a Pmax temperature coefficient of −0.29%/°C, which ranks among the lowest in its class. In practice, this means that at a typical module operating temperature of 65°C, the panel loses approximately 10% of its rated power output, whereas an older PERC module would lose approximately 13–14%. Over the course of a full year and across an entire farm, this difference translates into measurable additional kilowatt-hours of generation and better alignment with production forecasts during summer months. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1675082519690afbcf4cd56-4351cc7fc720.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -45 W, lighter, +1.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -50 W, lighter, +1.7 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +1.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | -30 W, lighter, +1.6 pp | | [AIKO AIKO-A690-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a690-mae78dw) | 690 W | -35 W, lighter, +1.4 pp | | [AIKO AIKO-A685-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a685-mae78dw) | 685 W | -40 W, lighter, +1.2 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +35 W, cooler, +1.2 pp | | [AIKO AIKO-A680-MAH78Dw](https://comparepv.com/panel/aiko-aiko-a680-mah78dw) | 680 W | -45 W, lighter, +1.0 pp | | [Canadian Solar CS7N-640MB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-640mb-ag) | 640 W | -85 W, hotter, -2.7 pp | | [Canadian Solar CS7N-645MS](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-645ms) | 645 W | -80 W, hotter, -2.5 pp | | [Canadian Solar CS7N-650MS](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-650ms) | 650 W | -75 W, hotter, -2.4 pp | | [Canadian Solar CS7N-655MB-AG](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-655mb-ag) | 655 W | -70 W, hotter, -2.2 pp | | [Canadian Solar CS7N-660MS](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-660ms) | 660 W | -65 W, hotter, -2.1 pp | | [Canadian Solar CS7N-665MS](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-665ms) | 665 W | -60 W, hotter, -1.9 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +80 W, cooler, +1.8 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +75 W, cooler, +1.6 pp | --- Source: https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs7n-725tb-ag Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
