Solar and battery installation, Sydney
Solar and battery installation covers designing and installing rooftop solar panels and home battery storage: new installs, upgrades to an existing system, or adding a battery to an existing solar array.
Government rebates, including federal small-scale renewable energy incentives and any current NSW-specific programs, can materially change the cost of a system, so it's worth having a specialist check your eligibility before committing to a quote.
Typical job value: $8,000 – $25,000

What's involved
Site assessment
A specialist assesses roof orientation, shading, your electricity usage and any relevant rebate eligibility to size the system.
Design and quote
Panel layout, inverter and battery, if included, are specified, with an itemised quote showing gross cost and applicable rebates.
Installation
Panels, inverter and battery, if applicable, are installed, typically within a day or two for a standard residential system.
Grid connection and sign-off
The system is inspected, connected to the grid with your electricity distributor's approval, and commissioned.
What affects the price
- System size: kW of panels, kWh of battery storage
- Panel and inverter brand and quality
- Roof type and access, including pitch and number of storeys
- Whether a battery is included
- Current rebate eligibility, which changes the net cost
Licensing and permits
Solar installations in NSW must be carried out by a Clean Energy Council (CEC) accredited installer for the system to be eligible for government rebates, and the installing electrician must hold a current NSW electrical licence. Grid-connected systems also require approval from your local electricity distributor.
Common questions
What rebates am I eligible for?
This depends on your system size, location and current government schemes, which change over time; a CEC-accredited installer can confirm your specific eligibility and factor it into your quote.
How long does installation take?
A standard residential solar system is often installed within a day; adding a battery or a larger commercial system can take longer.
Do I need a battery, or is solar alone worth it?
It depends on your usage pattern and electricity plan: solar alone offsets daytime usage, while a battery stores excess power for use at night. A specialist can model your usage to show which makes more financial sense for your household.
What happens on a cloudy day or at night?
Without a battery, you draw power from the grid as usual. With a battery, stored solar energy is used first, and the grid is a backup once the battery is depleted.
How long do solar panels and batteries last?
Panels typically carry 20–25 year performance warranties; batteries are generally warranted for 10 years, though actual lifespan depends on usage and battery chemistry.
Can I add a battery to my existing solar system later?
In most cases yes, provided your existing inverter is compatible or a compatible battery/inverter combination is chosen; a specialist can assess your current system.
