Map your roof's solar potential

If you are considering installing solar, try out SunSPoT. This great tool will help you calculate how much electricity and money a solar PV system could save your home or business.

The tool is based on detailed modelling which takes accounts of solar radiation, tilt, orientation and shading at your home or business. Council worked with the Australian Photovoltaic Institute (AVPI) to map the Inner West area so that you can select your own rooftop and receive personalised information.

  • financial benefits of solar power
  • getting to know solar technology
