Panel technology moved fast in the last three years. Here is what the labels actually mean for your roof.

Mono PERC

The proven standard — 540–555W panels at the best price per watt. Perfect for straightforward rooftop arrays where space is adequate.

Bifacial

Generates from both faces; gains 5–15% extra on reflective surfaces or raised structures. Canadian Solar BiHiKu-style modules are widely used on elevated frames in Pakistan.

N-Type TOPCon

The newest mainstream tech: 580–605W, better low-light response, lower degradation (≈1% first year, 0.4%/yr after), and stronger temperature performance — ideal for hot Pakistani summers. Suntrix N-Type 585–605W panels carry 25–30 year performance warranties.

Practical Advice

Match total array wattage to your inverter’s PV input limit (usually 1.2–1.5× the AC rating), and always check the datasheet’s temperature coefficient — we publish it on every product page.
