In practice, at a cell temperature of 70°C (typical summer conditions on a Polish rooftop), this difference translates to approximately 2–3% higher energy yield relative to a comparable PERC installation of the same STC-rated power. - **30-Year Linear Power Warranty** - The manufacturer provides a 30-year linear power warranty across the entire series — on par with peer comparables such as the Jinko Tiger Neo and Renesola RS7-N — backed by a Tier 1 manufacturer with over 20 years of market track record (Canadian Solar, founded 2001). For commercial investors and externally financed projects, this carries significant weight in LCOE valuation. - **BNEF Tier 1 Manufacturer – Confirmed Bankability** - Canadian Solar appears on the BNEF Tier 1 Solar Module Manufacturers list for Q1 2026, meeting the non-recourse financing criteria for at least six projects above 10 MW across six independent banks. This is a critical criterion for commercial projects and externally co-financed installations where manufacturer bankability is a formal condition of project financing. - **Wide Power Range and Large Number of Variants** - 34 variants spanning 425–635 Wp enable precise module power selection for any project without over-sizing — suitable for both small prosumer installations and large-scale farms. A 210 Wp spread within a single series is uncommon in the market and facilitates procurement standardization while preserving design flexibility. - **LID Elimination and PID Resistance** - N-type cells are boron-free and therefore immune to Light-Induced Degradation (LID) typical of P-type PERC modules. Combined with certified resistance to Potential-Induced Degradation (PID), the series maintains more stable long-term energy yield — a notable advantage in system installations operating at higher string voltages (up to 1500 V). ## Cons - **Monofacial Construction Only** - The TOPHiKu6 series does not offer a bifacial variant — bifacial counterparts are available separately as the TOPBiHiKu6. For ground-mount or flat-roof installations over high-albedo surfaces (albedo >0.25), bifacial modules typically deliver 5–15% higher annual energy yield, which at utility-scale directly translates to a lower LCOE. Investors planning such installations should consider the alternative series. - **Inconsistent Product Warranty Across the Series** - The materials and workmanship warranty varies within the series from 12 to 25 years depending on the variant. Variants carrying a 12-year warranty fall significantly short of the current market standard (e.g., Jinko Tiger Neo offers 25 years), making it essential to verify the warranty datasheet for any specific model selected — particularly important for projects with long financing horizons. ## About this series The Canadian Solar TOPHiKu6 series comprises monofacial modules based on **N-type cells in TOPCon technology**, designed for stable energy production over the long term. In practice, this means lower power degradation over time and better performance in challenging operating conditions, where standard modules tend to lose performance faster. The application of **a multi-string busbar structure (16BB)** improves current collection and minimizes the impact of micro-cracks, resulting in predictable energy yields throughout the installation's lifecycle. The TOPHiKu6 series also stands out due to its **low sensitivity to high temperatures**, making it suitable for heated roofs during summer and installations with limited module-under ventilation. This makes it an excellent choice for investors seeking to reduce energy costs without oversizing the project - the series helps minimize BOS components and better utilizes the available space. For investment security, the **long linear power warranty** is also crucial, both for residential and commercial projects. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - Power density of 227.7 W/m² matches the \*\*TOPCon 450-500W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - In the top 19% for efficiency among all TOPCon panels ## Questions ### What warranty is offered on Canadian Solar TOPHiKu6 panels and what does it cover? The TOPHiKu6 series is backed by a 25-year product warranty (covering materials and workmanship) and a 30-year linear power output warranty. A linear warranty means that degradation is distributed evenly over the entire period, with no steep drop-off in the early years. By comparison, many lower-cost modules offer only a 10–12 year product warranty and a 25-year power warranty, making the TOPHiKu6 a safer choice for long-term investments. ### What is TOPCon technology and why should you choose it in the TOPHiKu6 series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology in which a thin silicon oxide layer suppresses charge carrier recombination. In practice, this translates to higher conversion efficiency, a lower temperature coefficient (approx. −0.29 %/°C), and less degradation over time compared to mainstream PERC modules. TOPHiKu6 modules reach up to 635 Wp, delivering more energy from the same roof area. ### Do Canadian Solar TOPHiKu6 panels perform well in summer heat? Yes. Thanks to a low power temperature coefficient of −0.29 %/°C, TOPHiKu6 panels lose significantly less output as temperature rises compared to older PERC modules (typically −0.35 %/°C). This means that on a hot roof at midday in summer, power losses are measurably lower, which directly translates into higher annual energy yields under Central European climate conditions. ### Is the TOPHiKu6 series suitable for a small rooftop installation on a single-family home? Absolutely. While the series includes variants up to 635 Wp intended for commercial projects as well, the smaller models in the TOPHiKu6 family (e.g., 440–470 Wp) are well suited for pitched residential roofs. The physical dimensions and weight of a typical module are comparable to standard panels, and the high efficiency allows more power to be harvested from a limited roof area. ### How does the Canadian Solar TOPHiKu6 differ from the brand's older PERC modules? The key difference lies in the cell technology: the TOPHiKu6 uses N-type TOPCon cells instead of P-type PERC cells. N-type cells inherently exhibit lower light-induced degradation (LID), better performance at elevated temperatures, and higher module efficiency. In addition, the use of 16 busbars (versus 9–12 BB in earlier generations) improves current collection and reduces the impact of microcracks on energy yield throughout the entire system lifetime. ### Is Canadian Solar a reliable manufacturer and is the TOPHiKu6 series currently available on the market? Canadian Solar is a Bloomberg NEF Tier 1 manufacturer, placing it in the highest category of financial and operational creditworthiness in the photovoltaic industry. The company has been in operation for over 20 years and owns its own production facilities. The TOPHiKu6 series is actively available for sale and has not been discontinued, ensuring warranty service availability throughout the full 30-year power output warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1671737436893527184c9d-43228ee23a31.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, lighter, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, lighter, +1.7 pp | | [Canadian Solar CS6.2-48TD-435](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-435) | 435 W | -20 W, -1.0 pp | | [Canadian Solar CS6.2-48TD-440](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-440) | 440 W | -15 W, -0.8 pp | | [Canadian Solar CS6.2-48TD-445](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-445) | 445 W | -10 W, -0.5 pp | | [Canadian Solar CS6.2-48TD-450](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-450) | 450 W | -0.3 pp | | [Canadian Solar CS6.2-48TD-460](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460) | 460 W | Very close match | | [Canadian Solar CS6.2-48TD-465](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-465) | 465 W | +10 W, +0.5 pp | | [Canadian Solar CS6.2-48TD-470](https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-470) | 470 W | +15 W, +0.7 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/csi-solar-co-ltd-canadian-solar-cs6-2-48td-455 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
