Why Sydney Homeowners Are Switching to Solar
Sydney receives an average of 4.8–5.2 peak sun hours per day, making it one of the most solar-viable cities in Australia. For households connected to the Ausgrid network, electricity rates have continued to rise — many Sydney families are paying over $1,800–$2,500 per year in power bills before solar. A standard 6.6kW solar system in Western Sydney can generate enough energy to offset the majority of a household’s daytime usage, with typical payback periods of 3–5 years.
NSW homeowners may also be eligible for federal Small-scale Technology Certificates (STCs), which reduce the upfront cost of installation — and with the federal battery rebate of up to $16,800 available in 2026, there has never been a better time to add battery storage. Austar Solar handles the STC paperwork and rebate applications on your behalf.
Our Solar Services in Sydney
- Solar Panel Installation Sydney
Supply and install CEC-certified solar panels sized for your Sydney home or business. Whether you’re looking for a compact 6.6kW starter system or a large 13kW+ setup, our Western Sydney team designs every installation around your roof, your usage, and your budget. - Battery Storage Installation Sydney
Add a Tesla Powerwall, Sungrow, or Sigenergy battery to store your solar energy and reduce grid dependence. Battery storage means you keep using your own solar power after sunset — and stay protected when electricity prices spike. - Solar + Battery Packages Sydney

Charge your electric vehicle at home using your own solar energy with a professionally installed EV charger. Our Sydney team installs wall-mounted AC chargers that integrate with your solar system, so your car runs on sunshine — not the grid. - Solar Panel Cleaning Sydney

Frequently Asked Questions — Solar Installation in Sydney
How much does a solar system cost in Sydney?
A 6.6kW solar system in Sydney typically costs between $5,000 and $8,500 after the federal STC rebate, depending on the panel brand and inverter chosen. Premium systems using brands like REC or Jinko with a quality inverter sit toward the higher end, while entry-level systems with tier-one panels can be more affordable. Austar Solar provides obligation-free quotes tailored to your roof and energy usage.
How many solar panels do I need for a Sydney home?
For an average Sydney household using 20–25 kWh per day, a system between 6.6kW and 10kW is typically recommended. This translates to roughly 16 to 24 panels depending on panel wattage. Our team assesses your actual electricity bills and roof orientation before recommending a system size — north-facing roofs in Western Sydney generally achieve excellent output year-round.
Is solar worth it in Sydney?
Yes — Sydney is one of the best cities in Australia for solar returns. With high electricity rates on the Ausgrid network and strong solar irradiance averaging 4.8–5.2 peak sun hours per day, most Sydney households see a payback period of 3–5 years and savings of $1,200–$2,000+ per year. Systems installed today are typically warrantied for 25 years.
What solar rebates are available in Sydney in 2026?
Sydney homeowners are eligible for federal Small-scale Technology Certificates (STCs), which reduce the upfront cost of a new solar installation by $1,500–$3,500 depending on system size. In 2026, the federal government’s battery rebate program also offers up to $16,800 for eligible households adding battery storage. Austar Solar manages all rebate paperwork as part of the installation process.

How long does a solar installation take in Sydney?
Most residential solar installations in Sydney are completed within one day. The process includes roof mounting, panel installation, inverter setup, and connection to your switchboard. Grid connection approval through Ausgrid typically takes a few additional business days after installation, after which your system begins feeding energy back to the grid.
Can I add battery storage to an existing solar system in Sydney?
Yes — Austar Solar installs battery storage on both new and existing solar systems. We stock and install Tesla Powerwall, Sungrow, Sigenergy, AlphaESS, and other leading battery brands. Our Sydney team will assess your existing inverter compatibility and recommend the right battery size based on your household’s evening energy usage.
