The Canadian Solar TOPHiKu6 CS6.2-54TM is a 108-cell N-type TOPCon module rated 520 W, notable for 23.4% module efficiency — among the highest figures in the range we install. In practice that means more capacity per square metre of roof. At 1961 mm it sits between residential and industrial formats, so it lays out sensibly on larger house roofs, flat roof decks and commercial buildings alike.
What is the TOPHiKu6 CS6.2-54TM, and why does 23.4% efficiency matter?
Canadian Solar is a long-established manufacturer with a real service presence in Thailand. The TOPHiKu6 series uses N-type TOPCon cells like other current premium modules, and the CS6.2-54TM is the 108-cell general-purpose format, equally at home on residential and commercial jobs. Module efficiency of 23.4% is worth interpreting correctly. It does not mean this panel generates more energy than others in every situation — it means more watts from the same area. Where roof space is the binding constraint, such as a shophouse roof deck or a town house with only a few usable square metres, higher efficiency delivers a larger system on the same footprint. Where roof area is plentiful, cost per watt and layout convenience matter more.
Highlights from the datasheet
- 23.4% efficiency: among the highest we install, maximising capacity on constrained roofs
- Versatile 1961 mm format: longer than a typical residential module but shorter than industrial formats, suiting large homes, decks and commercial roofs
- 23.3 kg: manageable for manual handling on most installations without crane hire
- −0.29%/°C temperature coefficient: better heat behaviour than older P-type modules, which matters in Phuket's year-round warmth
- 15-year product warranty: longer than the 12 years common in the market, alongside 30-year performance cover
- −40 to +85°C operating range: wider than many modules, comfortably covering rooftop temperatures on metal sheet in full sun
- IP68 junction box with three bypass diodes: limits the impact when part of the module is shaded

Why this model suits Phuket
- Constrained urban roofs: 23.4% efficiency delivers the target system size on shophouse decks and town properties with limited area
- Year-round heat: the −0.29%/°C coefficient and +85°C operating ceiling suit real rooftop conditions here
- Heavy rain and humidity: IP68 junction box and anodised aluminium frame are appropriate for island conditions
- Salt air: on coastal work we pair the module's aluminium frame with stainless fixings at every mounting point
Who it suits
- Properties where roof area limits system size: maximum output from the space available
- Medium to large homes: 5–15 kWp systems wanting high efficiency in a manageable format
- Commercial buildings and offices: roof decks where watts per square metre is the priority
- Owners who weigh product warranty heavily: 15 years on the module itself
- Projects that want an established brand with local support: Canadian Solar has service channels in Thailand
Summary
The Canadian Solar TOPHiKu6 CS6.2-54TM 520W combines 23.4% module efficiency with a format that still lays out flexibly, making it a strong choice where roof area constrains system size — town houses, shophouse decks and commercial buildings. It carries a 15-year product and 30-year performance warranty. If appearance is a priority, the All-Black CS6.2-48TD 465W is the aesthetic option in the same family.
