Frequently Asked Questions

Are there any rebates or incentives available for solar in NSW?
Yes. NSW residents may be eligible for federal incentives under the Small-scale Renewable Energy Scheme (SRES), which offers upfront discounts via Small-scale Technology Certificates (STCs). You may also qualify for additional state-based rebates or interest-free loans. Our team can help you understand what’s available and guide you through the application process.
How long do solar panels last?
Most high-quality solar panels come with a 25-year performance warranty. With proper care and regular maintenance, your system can continue producing clean energy efficiently well beyond that.
Do I need council approval to install solar panels in Wollongong?
In most cases, council approval isn’t required for rooftop solar installations that comply with NSW development standards. We’ll take care of all the necessary checks to ensure your system meets local regulations.
Can I add a battery to my solar system later?
Absolutely. Our systems are designed with future flexibility in mind. If you’re not ready to add a battery now, we can ensure your solar system is battery-ready for a smooth upgrade later.
What is the best direction to install solar panels in Wollongong?
North-facing panels usually offer the best energy production in Australia. However, depending on your roof layout and daily energy usage, east or west-facing panels may also be suitable. We design each system to maximise efficiency for your specific property.
Do solar panels work on cloudy days?
Yes, they do. Solar panels still generate electricity on cloudy or overcast days, though at a lower output. Our systems are designed to perform reliably in all typical Wollongong weather conditions.
Can I use solar power at night or during a blackout?
To access solar power at night or during a blackout, you’ll need a battery storage system. Batteries store excess energy produced during the day so you can use it when the sun isn’t shining.
Do you provide solar panel maintenance and repair services?
Yes. Whether we installed your system or not, we offer complete maintenance services, including panel cleaning, system health checks, inverter replacements, and fault diagnostics to ensure your system runs at peak performance.
Are your solar installers certified?
Yes. We are accredited by the Clean Energy Council (CEC), which means our work meets the highest Australian standards for safety, compliance, and quality.
How long does it take to install a solar power system?
Most standard residential installations are completed in one to two days. We’ll provide a clear timeline and keep you updated at every stage of the process.
