The technology

Why bifacial N-Type TOPCon panels?

N-Type TOPCon cells are the current top generation in photovoltaics: higher efficiency per m², much slower degradation and better performance at high temperatures than classic PERC panels.

The bifacial rear side also captures light reflected from the roof or ground — it can raise total production, depending on mounting and surface area — and the 2 mm dual glass makes them practically immune to microcracks and moisture.

✓Under 1% degradation in year one and ~0.4%/year after — 87.4% power guaranteed at 30 years
✓Low temperature coefficient — they produce more in summer heat
✓Excellent performance in diffuse light too — mornings, evenings, overcast skies

Which panel should I choose for my project?

The right choice depends on the available roof area and the target system power.

570–640 W
Homes / small roofs
Compact modules, easy to integrate on roofs with limited or fragmented space.
600–650 W
Large homes / high consumption
Higher-power panels, suited for hybrid kits with battery and heat pumps.
700–730 W
Warehouses / commercial projects
Large modules for high installed power and efficient mounting — warehouses, carports, ground.
Want a complete system, not just panels?

Choose a hybrid kit with inverter, battery, installation and commissioning included.

Panels are sized based on your roof, consumption and project goal.
