Overview
Despite the ‘HJT’ label commonly used for this listing, Canadian Solar’s well-documented 635W module in this power class — the TOPBiHiKu7 CS7L-635TB-AG — is built on N-Type TOPCon cell technology, not true Heterojunction (HJT). Canadian Solar does not currently publish a mainstream HJT-branded 635W product in its public datasheet library. It’s still a strong large-format bifacial module: 120 half-cut cells on the 210mm platform, aimed at utility and large C&I ground-mount.
Where This Panel Fits
At 635W, the Canadian HJT 635W N-Type Bifacial is sized for residential rooftops and small-to-medium commercial net-metering systems. It’s light and compact enough for standard rafter-mounted racking, and its physical dimensions match the string voltage ranges most residential hybrid inverters sold in Pakistan are designed around — so pairing it with a common local inverter brand shouldn’t require any unusual string configuration.
Key Features
N-Type TOPCon Cells
High efficiency with low LID/LeTID degradation.
Large-Format 210mm Platform
Fewer modules per kWp lowers racking, cabling and labour cost.
Bifacial Dual-Glass
Rear-side yield gain on elevated or reflective ground-mount racking.
Low-Voltage String Design
Reduces balance-of-system cost across long utility strings.
High Mechanical Load Rating
Built for utility-scale wind/snow exposure.
30-Year Linear Warranty
Standard Canadian Solar performance guarantee.

System Sizing Example
A rough guide to how many Canadian HJT 635W N-Type Bifacial panels a typical grid-tied or net-metering system would need, before accounting for shading, orientation losses, or inverter clipping:
| Target System Size | Panels Needed | Resulting Array Size |
|---|---|---|
| 3 kW system | 5 panels | 3.17 kW actual DC array size |
| 5 kW system | 8 panels | 5.08 kW actual DC array size |
| 10 kW system | 16 panels | 10.16 kW actual DC array size |
These figures are a starting estimate only — your installer should size the final array against your actual roof space, shading conditions, and inverter’s DC input limits. WhatsApp 0300-0644424 with your rough monthly electricity bill and we can help estimate the right system size for your usage.

Why Buy This Panel from Pakistan Solar Traders
We stock the Canadian HJT 635W N-Type Bifacial alongside dozens of other Canadian Solar and competing-brand panels, so you get a genuine
point of comparison rather than a single-brand sales pitch. Because bifacial panel prices move daily with
USD/PKR exchange rates and international module costs, we don’t publish a fixed price on this page — WhatsApp
0300-0644424 or call UAN 0304-1111988 and we’ll confirm today’s rate, current stock, and a realistic delivery
timeline to your city immediately.
Maintenance in Pakistani Conditions
Dust accumulation is the single biggest performance drag on solar panels in most of Pakistan, particularly
in Punjab and Sindh during the dry pre-monsoon months — a heavily dust-coated Canadian HJT 635W N-Type Bifacial can lose 10-15% of
its rated output before it becomes visibly obvious. A simple monthly rinse with water (avoid abrasive cleaning
or harsh detergents that can degrade the anti-reflective glass coating) is usually enough to keep a rooftop
array performing close to its 635W rated capacity. In coastal areas like Karachi, periodically check the
frame and junction box for salt residue, since prolonged salt exposure can accelerate corrosion on lower-quality
frame coatings over many years — one more reason Tier-1 branded panels with proper IP68-rated junction boxes are
worth the price difference over unbranded alternatives.
Frequently Asked Questions
What is the price of Canadian HJT 635W N-Type Bifacial in Pakistan?
Prices change daily with USD/PKR exchange rates and international module costs, so we don’t list a fixed price here. WhatsApp 0300-0644424 or call UAN 0304-1111988 and we’ll confirm today’s best price on this panel immediately.
Is the Canadian HJT 635W N-Type Bifacial bifacial or monofacial?
This is a bifacial N-Type solar panel rated at 635W under Standard Test Conditions (STC). Bifacial panels also generate power from their rear side when mounted with a reflective or elevated surface underneath.
What warranty does Canadian Solar offer on this panel?
Canadian Solar panels in this catalog typically carry a 12–15 year product warranty and a 25–30 year linear power output warranty. Exact terms depend on the specific model and import batch — confirm with your invoice.
How many units can a 635W panel generate per day in Pakistan?
As a rough estimate, a 635W panel produces around 2.86–3.49 kWh per day under typical Pakistani sun hours (4.5–5.5 peak sun hours), before system losses and inverter efficiency.
Where can I buy Canadian HJT 635W N-Type Bifacial in Pakistan with fast delivery?
Pakistan Solar Traders stocks and ships this panel nationwide. WhatsApp 0300-0644424 or call UAN 0304-1111988 to confirm current stock, price and delivery timeline to your city.
