Question 1

How much does solar installation cost in Sydney?

Accepted Answer

A standard 6.6kW rooftop solar system in Sydney costs $4,000–$8,000 after the Small-scale Technology Certificate (STC) rebate. Larger 10kW systems run $7,000–$13,000. Battery storage (e.g., Tesla Powerwall 3) adds $12,000–$16,000 installed. Prices vary based on panel brand, inverter brand, roof complexity, and storey height.

Question 2

Do I need a licensed electrician for solar installation in NSW?

Accepted Answer

Yes — solar PV installation in NSW requires a licensed electrician who also holds Clean Energy Council (CEC) accreditation. The CEC accreditation is separate from the NSW electrical contractor licence and is required to qualify for the federal STC rebate. Your solar electrician will connect the inverter to your switchboard, arrange the grid-connect approval with your energy retailer, and issue a Certificate of Compliance for Electrical Work (CCEW). All solar electricians in our network hold both NSW Fair Trading electrical licences and CEC accreditation.

Question 3

What is the difference between a solar installer and a solar electrician?

Accepted Answer

A solar installer typically refers to the company or person who designs the system and manages the project. The solar electrician is the licensed tradesperson who performs the actual electrical connection work — mounting the array, running the DC cables, installing the inverter, connecting to the switchboard, and arranging grid connection approval. In NSW, only a licensed electrician can perform the electrical connection work. Many solar companies employ licensed electricians in-house; others sub-contract the electrical work.

Question 4

What government rebates are available for solar in Sydney?

Accepted Answer

The main federal incentive is Small-scale Technology Certificates (STCs), which provide an upfront point-of-sale discount on new solar systems based on system size, location, and years remaining until 2030. STCs are typically assigned to the installer and deducted from your purchase price. NSW does not currently have a state-specific solar rebate, but the federal STC scheme applies statewide. Battery storage may be eligible for interest-free loans through NSW government energy schemes — your installer can advise on current offers at the time of quoting.

Question 5

How long does solar installation take in Sydney?

Accepted Answer

A standard residential rooftop solar installation takes one to two days on site. Grid connection approval from your energy retailer (Ausgrid or Endeavour Energy for network approval) typically takes 5–15 business days after installation, during which the system may generate power but not export to the grid. Your solar electrician manages the grid connection application. Total project timeline from quote to grid-connected is typically 3–6 weeks.

Question 6

Can I add a battery to my existing solar system in Sydney?

Accepted Answer

Yes — battery storage can be retrofitted to most existing solar systems in Sydney, though compatibility depends on your inverter type. AC-coupled batteries (such as Tesla Powerwall) work with virtually any existing inverter. DC-coupled batteries require a hybrid inverter, which may mean replacing your existing inverter. Your solar electrician will assess your current system's compatibility and recommend the most cost-effective battery option. Some retrofits also require a switchboard upgrade.

Question 7

Who approves the grid connection for solar in Sydney?

Accepted Answer

Grid connection approval is provided by the distribution network operator (DNO) — either Ausgrid or Endeavour Energy, depending on your Sydney suburb. Your solar electrician submits a grid connection application on your behalf. For systems up to 10kW single-phase or 30kW three-phase, approval is typically granted automatically or within a few business days. Larger systems may require a more detailed technical assessment. Level 2 ASP work is not required for standard residential solar grid connections.
