Solar Panels and Your Home

Solar panels on roof

With increasing electricity prices, now is a great time to join over 1,400 Woollahra households that have a rooftop solar system. 

Rooftop solar photovoltaics (PV) systems convert the sun’s energy into electricity to power your home and sell any excess electricity back into the central grid.

These systems generally pay themselves back in as little as three to seven years and reduce average household energy bill by hundreds of dollars each year.

Where do I start?

1. Check your roof with the free SunSPot tool

Discover if your roof is right for solar panels with a free, not-for-profit online tool that helps you check the solar potential of your roof.

We have partnered with SunSPoT, from the Australian Photovoltaic Institute, to provide an easy-to-use service to residents and businesses in our area. Built by engineers at University of NSW, SunSPoT will help you calculate the potential system size, output for solar on your roof.

Watch the video or enter your address into the SunSPoT website and find out how you could use solar on your roof.

Do I need Council approval to install Solar PV?

We recommend the first port of call is for you to call our Duty Planner on 9391 7000. Our Duty Planner is here to help and will provide advice about the appropriate process to follow for your property.

Installing a solar PV system may not need Council approval if the proposal meets the relevant standards in State Environmental Planning Policy (Transport and Infrastructure) 2021. These requirements relate to details such as the size of the system, installation standards, the direction the panels face and the distance the panels protrude from the roofline. The full standard is available here: State Environmental Planning Policy (Transport and Infrastructure) 2021. Also refer to Part 2.3, Division 4, Electricity generating works for solar energy systems.

A Development Application (DA) is required for a solar energy system when the system does not meet these standards. If you need to submit a DA, Council will waive all fees for DAs that are solely for solar PV systems. Learn more about our DA process and access the relevant forms. The DA plans can be simple and should include a plan of the property, and the location and size of the proposed solar panel system. The relevant objectives and controls are contained in E6.3 of the Woollahra DCP 2015.

What if I can’t have a rooftop solar PV system?

Switch to GreenPower

If your roof is unsuitable for a rooftop solar system, or you are a renter, you can power your home with renewable energy by purchasing GreenPower through your electricity retailer.

GreenPower is the only voluntary government accredited program that enables your electricity provider to purchase renewable energy on your behalf. An ACT, NSW, VIC and TAS State Governments joint initiative, GreenPower guarantees that the renewable energy you are buying is helping to develop new renewable energy projects.
