How to read this map

  • It is an estimate for the area, not a quote. It doesn't allow for shading from hills, trees or nearby buildings, or for a roof's real size, pitch and direction.
  • The figure is for a 4 kWp system, about ten panels, on a 35° south-facing roof with 14% system losses, from satellite sunshine data.
  • Typical is the middle figure across the postcodes of every home in East Lothian. A home in a sunnier or duller square can sit above or below it.
  • It is not a savings figure: that depends on how much of the electricity the home uses and its tariff.
