Solar Panels for Roof — How to Choose and How Many You Need

Rooftop solar power stations are the most popular way to install solar panels. Panels are mounted on special brackets at optimal angle, without taking useful yard space. Monocrystalline modules from 400 to 630W provide maximum generation per square meter of roof.

How Many Solar Panels for Your Roof

  • Small roof (20-30 m²) — 8-12 panels 400W, total 3.2-4.8 kW
  • Medium roof (30-50 m²) — 10-16 panels 500W, total 5-8 kW
  • Large roof (50-80 m²) — 12-20 panels 600W, total 7.2-12 kW
