How it works

Five steps, about three minutes

  1. 1

    Find your house

    Search your address or use your location, then confirm your roof on the satellite map.

  2. 2

    Mark what is on the roof

    Water tanks, stair rooms, trees and taller neighbours, with their real sizes and heights.

  3. 3

    Scan your surroundings

    Stand where the panels will go and sweep your phone across the buildings and trees. We show when they hide the sun.

  4. 4

    Get an honest plan

    Panels sized to your bill at the best tilt, with real sunshine data. If solar will not pay off, we say so.

  5. 5

    Take it to an installer

    Download a PDF report or share it on WhatsApp, with the questions to ask every installer.
