Six steps to installing solar
Thinking about solar? Work your way through the six step process to installing solar.
If you get through the steps and you've still got questions about properties that are heritage affected, refer to Council's Development approvals for solar page.

Take a look at the steps to follow below.
Step 1: Background reading
A good starting point is to read the Clean Energy Council’s Solar Guide for Consumers
Step 2: Have your energy bills ready
Ideally, pull out 12 months of electricity bills – this will help work out your solar needs and payback time.
Step 3: Check suitability of your roof
Use the Sunspot tool to help calculate what size system can fit on your roof and how much you could save per year on your electricity bills.
Step 4: Choosing a solar retailer
When choosing a solar retailer, it pays to do some research and get several quotes. Helpful reading:
The independent Energy Tech Guide directory prepared by Energy Consumers Australia lists the following new energy tech industry information resources
Step 5: Reviewing quotes, contracts and installation
Step 6: What should I expect on installation day?
Your solar installers should:
- Install your rooftop solar panels
- Run electric cables to your inverter
- Mount the inverter on your wall
- Connect the inverter to your smart meter
- Install isolation switches on the roof, next to your inverter, in your smart meter box
- Test the entire solar system
- Give you a demonstration of the system
- Ensure that you are satisfied with their work
- Ask you to sign the paperwork for the solar panel system, the Small Scale Certificates, any other state rebates.
What solar payback can I expect?
Your specific payback will depend on:
- how much electricity you use
- the time of day you use electricity
- your electricity price
- the size of the solar system
- the solar panels tilt, orientation and shading
In Sydney and on the coast of NSW, each kW of solar panels creates approximately 4 kWhs of electricity a day. For example, a 5kW solar system will generate about 20kWh a day, with some variation between summer and winter.
