Why choose Thirroul Solar
We’re not a door-to-door sales operation. Thirroul Solar is run by the same licensed electrical contractors who’ve been serving the Illawarra since 1991. That means a properly designed system, professionally installed, and an electrician who will still pick up the phone years later.
Solar panel system design & installation
We look at your roof, your usage and your goals - then design a system that actually fits. Every install is completed by our accredited team, tested and certified for the grid.
- On-site assessment and system design
- Quality panel and inverter selection
- Licensed electrical installation
- System commissioning and certification
Battery storage and backup power
Storing your solar in a battery means you get to use it after the sun goes down - and you can stay powered during blackouts. We’ll recommend storage that matches your system and usage patterns.
- Battery sizing and product selection
- Hybrid inverter installation
- Backup circuit wiring
- System monitoring setup
Grid connections, metering and upgrades
Connecting a new solar system to the grid involves paperwork, meter upgrades and utility approvals. Because we’re electrical contractors, we handle the complete process - not just the panels on your roof.

- Meter installations
- Metering and solar system upgrades
- Residential and commercial solar packages
Commercial solar
Larger systems for retail, industrial and commercial sites across the Illawarra - sized to your usage profile, designed for return on investment, and installed with minimal disruption to trading.
