‘SunSPoT’ solar calculator is now available to Hornsby Shire residents and businesses, to help you make an informed solar purchasing choice.

What will SunSPoT tell you?

SunSPoT provides answers to many confusing questions about solar for buyers including:

  • How much money will a solar PV system save me in a year?
  • What are the best areas for solar panels on my building roof?
  • What size system is best?
  • How much energy will it generate?
  • What should I be paying for a solar system?
  • How much more will I save with a battery?
What makes SunSPot different to other online solar calculators?

Your details are private
Unlike other online solar calculators, SunSPoT does not collect and share your details with solar sales companies. SunSPoT was built specifically to help small energy users (home and business owners).

Sophisticated software

SunSPoT’s clever 3D spatial mapping technology allows it to identify the tilt and orientation of a roof plane, and determine the impact of shading from buildings and trees throughout the year.

Tailored results

The results are uniquely tailored to your roof, your area and your electricity usage. Using average solar system pricing data provided by Solar Choice, and your personalised electricity billing data and usage info, the calculations provide a reliable benchmark that can be compared with quotes from solar sales companies.

If you’re thinking about getting solar, start your search with the free SunSPoT solar potential tool.

Here are a few other things to consider:

Solar for my household

Solar power is generated when the sun is shining, so if you can use the power generated on your roof during daylight hours it is FREE. Some households place appliances, such as dishwashers and washing machines, on timers to come on during the day whilst they are at work and the sun is shining.

Great Investment

In general you can expect an average payback period of 7 years for your solar investment. Of course this may be less depending on your household electricity consumption and system size. The savings however can be enjoyed for up to twenty-five years, which is the lifetime of the panels. There is an upfront discount from the federal government that reduces the purchase price.


As the saying goes ‘you get what you pay for’. It is best not to make your investment decision based on the cheapest price. A quality solar systems warranty is at least twenty-five years on the panels and ten years for an inverter.

Council supports the installation of solar across the Shire and currently generates 207 kW of electricity from renewable sources, located at Council facilities such as libraries and parks. Please refer to Council’s Renewable Energy Sites page.
