Performance is confirmed by independent testing as reported by pv magazine (April 2025). - **N-type TOPCon — low Tc and minimal degradation** - The temperature coefficient of -0.29%/°C outperforms typical PERC cells (-0.35%/°C), translating to approximately 3.5% higher power output at a module operating temperature of 70°C. Annual linear degradation is rated at 0.4%, with first-year degradation capped at 1.0%, significantly reducing the risk of LID/LeTID associated with P-type cells. - **30-year linear power output warranty** - The manufacturer guarantees a degradation rate not exceeding 0.4% per year over 30 years. Among peer comparables — Jinko Tiger Neo, Leapton, and AUSTA ENERGY — this represents one of the longest and most precisely defined warranty regimes in the 600–630 Wp power class. - **Bifacial dual glass — bifaciality factor up to 85%** - The dual glass construction with a bifaciality factor of up to 85% enables additional energy harvest from ground albedo, yielding an estimated 5–15% increase in annual energy production compared to monofacial modules in ground-mount applications. The rear glass replaces the traditional backsheet, improving mechanical integrity and eliminating the risk of UV-induced backsheet degradation. - **Efficiency up to 23.3% — top-tier performance in its class** - The peak efficiency of 23.3% (630 Wp model) is virtually on par with the segment leader among peer comparables — the Jinko Solar Tiger Neo 66HL4M-BDV (23.32%) — and exceeds both the Leapton LP182\*199-M-72-NH and the AUSTA ENERGY AU-156MH (22.54%) by more than 0.75 percentage points. This directly reduces the roof or land area required to achieve the same installed capacity. ## Cons - **Weight of 40.6 kg — heavy dual glass construction** - The dual glass build and reinforced 35 mm frame bring the module weight to approximately 40.6 kg, while comparable monofacial modules in the same power class typically weigh around 30–33 kg. In practice, this requires heavier-duty mounting structures and greater installation labor, increasing balance-of-system (BoS) costs — a particularly critical consideration for rooftop installations with limited load-bearing capacity. ## About this series The Canadian Solar TOPBiHiKu6 Anti-Hail series consists of specialized photovoltaic modules that set a new standard for durability in harsh weather conditions. They utilize advanced **N-type TOPCon cell technology**, which ensures not only high efficiency but, above all, excellent resistance to power degradation over time. A key differentiator of this line is its above-average mechanical resistance, confirmed by rigorous testing against large hailstone impacts. Thanks to the use of a reinforced construction, this solution eliminates the risk of micro-cracks, which often disqualify standard panels after severe storms. The **bifacial dual glass** design enables active energy production from both sides of the module, which, combined with high resistance to external loads, makes them ideal for solar farms and large commercial installations. It is a **hail protection system** that provides investors with peace of mind in an era of increasingly frequent extreme climate events. Unlike the competition, this series does not focus solely on electrical parameters but offers **maximum mechanical safety** and durability for decades. This is the optimal choice for projects implemented in regions with high weather risks, where the priority is operational continuity and the structural integrity of the components. ## Notable figures - Efficiency of 22.4% matches the \*\*TOPCon 600-650W\*\* median - At 224.0 W/m², this panel generates 3.7 W/m² less per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - At 40.6 kg, this panel is 7.9 kg heavier than the \*\*TOPCon 600-650W\*\* median (32.7 kg) - more demanding for installation crews - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What hailstone size can the Canadian Solar TOPBiHiKu6 Anti-Hail panels withstand? The TOPBiHiKu6 Anti-Hail series is rated to withstand hailstone impacts up to 55 mm in diameter in accordance with IEC 61215. This is achieved through a reinforced 35 mm frame profile combined with 2.5 mm tempered glass on both sides of the module. That is more than twice the threshold required by the standard hail test (25 mm), making this series among the most mechanically resilient modules currently available on the market. ### What warranty does Canadian Solar offer on the TOPBiHiKu6 Anti-Hail panels? Canadian Solar provides a 12-year product warranty covering material defects and manufacturing faults, along with a 30-year linear power output warranty. The power warranty guarantees that after 30 years of operation the module will retain a correspondingly high percentage of its nominal rated power. As a Tier 1 manufacturer with a global service network, Canadian Solar fulfills these warranty obligations directly, without third-party intermediaries. ### What does TOPCon technology mean in the TOPBiHiKu6 panels, and is the price premium justified? TOPCon (Tunnel Oxide Passivated Contact) refers to N-type cells distinguished by a lower temperature coefficient (−0.29%/°C) and higher efficiency (up to 23.3%) compared to legacy PERC cells. In practice, this translates to better energy yield during summer months and reduced losses under high-temperature conditions. For installations designed to operate over multiple decades, the lower long-term degradation inherent to N-type technology delivers a measurable return on the additional upfront investment. ### Are the Canadian Solar TOPBiHiKu6 Anti-Hail panels suited for utility-scale solar farms or only for residential rooftops? This series is designed primarily for utility-scale solar farms and large commercial installations. With power output up to 630 Wp, a bifacial dual-glass construction, and above-standard mechanical resistance, these modules meet the demands of large-scale projects — particularly in regions exposed to hailstorms. For a typical single-family residential rooftop, the modules are too large and heavy; smaller Canadian Solar series are a more appropriate fit for that application. ### How does the bifacial design of the TOPBiHiKu6 Anti-Hail panels work, and how much additional energy can it generate? Thanks to the dual-glass construction (tempered glass on both sides) and bifacial cells, the rear side of the module captures light reflected from the ground surface, soil, or rooftop membrane. The bifaciality factor of this series reaches up to 85%, which under favorable conditions — high-albedo ground surface and optimal tilt angle — can increase annual energy yield by 5–25% compared to a monofacial module of the same nominal power rating. ### Will the Canadian Solar TOPBiHiKu6 Anti-Hail perform well in regions with frequent hailstorms, such as the Lesser Poland or Subcarpathian provinces? Yes, the TOPBiHiKu6 Anti-Hail series was developed specifically with such locations in mind. The reinforced 35 mm frame and 2.5 mm tempered glass provide protection against hailstones up to 55 mm in diameter, while resistance to PID (Potential Induced Degradation) and LeTID (Light and elevated Temperature Induced Degradation) ensures stable long-term performance over decades. For investors developing PV farms in southern Poland, where hail risk exceeds the national average, this series significantly reduces the risk of costly repairs and unplanned generation downtime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/CS-Datasheet-TOPBiHiKu6-Anti-Hail-CS6-2-66TB-HP-v14-EN-927a75192533.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +45 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +40 W, lighter, +2.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -45 W, 16 kg lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +35 W, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -50 W, 16 kg lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +30 W, lighter, +2.2 pp | | [Canadian Solar CS6.2-66TB-600HP](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600hp) | 600 W | Very close match | | [Canadian Solar CS6.2-66TB-610HP](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-610hp) | 610 W | +0.2 pp | | [Canadian Solar CS6.2-66TB-615HP](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-615hp) | 615 W | +10 W, +0.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +75 W, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +95 W, lighter, +2.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +90 W, lighter, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +65 W, lighter, +2.4 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +65 W, lighter, +2.4 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +65 W, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-605hp 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.
