How do I know whether my property is suitable for a solar installation?

Ideally, solar panels are placed on a roof that is oriented somewhere between north-east and north-west.

Other orientations are possible, but may incur additional installation costs or result in a loss in performance.

The roof must have enough space for the panels:

  • A 1.5 kW system takes up 6.5 metres x 1.6 metres or 3.5 metres x 3.5 metres.
  • A 2.2 kW system takes up 10 metres x 1.6 metres or 5 metres x 3.5 metres.
  • A 3.0 kW system takes up 13 metres x 1.6 metres or 6.5 metres x 3.5 metres.

The roof must have minimal or no shade covering it. If there are trees or adjacent buildings casting shadows across your roof, it may not be suitable for a solar installation.
