More energy
Higher cell efficiency means more units from the same roof area, and more savings on every bill.
N-type TOPCon panels

Why N-type
Built for heat, built to last
N-type TOPCon is the newer cell technology. Here is what it means on your roof.
Power from both sides
Bifacial modules also catch light bouncing off the roof or ground, adding yield from the rear face.
Slower ageing
At 0.40% a year after year one, the panels keep far more of their output across a 25 to 30-year life.
Fewer weak spots
Half-cut, multi-busbar cells and anti-PID materials reduce losses from shading, heat and voltage stress.
How bifacial works
Power from the front and the back
All three of our N-type lines are bifacial. The rear of each module is open to light, so it adds power the front alone would miss.
- 1The front does the main workDirect sunlight falls on the front face, just as with any solar panel.
- 2The roof or ground reflects lightSome sunlight bounces off the surface beneath the panels.
- 3The rear turns that into extra powerBifaciality of up to 80% means the rear side can produce up to 80% of what the front would from the same light. Light-coloured roofs and raised mounting structures gain the most.

- 2 mm ARC-coated, high-transmission glass
- Bifaciality up to 80 ±10%
- 10 and 12 busbar half-cut cells
- Only 0.40% degradation per year
- 30-year power warranty
- Anti-PID performance through materials control

M10 cells · clear backsheet
N-type bifacial transparent backsheet M10 HC
A clear backsheet keeps the module lighter than dual glass while still collecting light from the rear, with the widest choice of sizes in the range.
- 3.2 mm low-iron tempered front glass
- First-year degradation below 1.0%
- Bifaciality up to 80 ±10%
- 10 busbar half-cut cells

Choosing a size
Which module suits your roof?
A rough guide. After the free site survey we recommend the exact model for your space, shade and budget.
Compact rooftops
108-cell modules are smaller and lighter, easy to fit around tanks and parapets on home terraces.
Most homes
120-cell modules balance size and output for typical independent houses and villas.
Large roofs and businesses
132 and 144-cell modules mean fewer panels on big, open roofs, offices and warehouses.
Industrial and ground-mount
G12 modules suit factories and open land, cutting racking and wiring per kilowatt.

FAQs
Questions about N-type panels
What is an N-type TOPCon solar panel?
It is a newer type of solar cell. Compared with older P-type cells, N-type TOPCon cells convert more of the sunlight into power, lose less output in hot weather and age more slowly. On our range that means about 0.40% degradation a year after the first year.
Do bifacial panels really help on a rooftop?
Yes, as long as some light can reach the back of the panel. The gain depends on how reflective the surface underneath is and how high the panels are mounted. Light-coloured roofs and raised structures help most. We check this during the free site survey.
Which warranty do I get?
The dual glass M10 and G12 lines carry a 30-year power warranty. For the transparent backsheet line, we confirm the warranty terms with your quote.
Should I choose N-type or P-type?
Choose N-type if roof space is limited or you want the most output and the slowest ageing. P-type costs less up front and works well on larger roofs. See our P-type range or ask us to compare both for your roof.
Do you install the panels as well?
Yes. Our own team designs and installs every system, after a free site survey. We work from offices in Hyderabad and New Delhi. Call 9705 9705 45 to book one.
