Got questions about solar? We’ve answered the top solar FAQs to help you understand costs, savings, installation, rebates, and more in Australia.
Thinking about going solar but overwhelmed by all the jargon and mixed advice? You’re not alone. Whether you’re curious about cost, performance, rebates, or whether solar even works on cloudy days, we’ve got you covered.
Below are the top solar FAQs Australians ask before making the switch, answered clearly and honestly by industry experts.
1. Is solar power really worth it in 2025? ☀️
Yes, more than ever. With energy prices on the rise and government rebates still available, installing solar in 2025 delivers strong long-term savings. Most homeowners see a 50–70% reduction in power bills
2. How much do solar panels cost in Australia? ☀️
The average 6.6kW residential solar system costs $5,500–$8,000 after rebates, depending on brand, quality, and installer. Battery storage adds $7,000–$14,000, but this can also be offset with rebates like the VIC solar battery rebate.
💡 Pro Tip: Avoid choosing the cheapest system. Quality matters for long-term performance and warranty.
3. What rebates are available for solar in Australia? ☀️
There are federal and state-based solar rebates in 2025:
STCs (Small-scale Technology Certificates) reduce upfront cost Australia-wide
Victoria: Up to $1,400 for solar panels + 0% interest loan, and $2,950 for batteries
NSW & SA: Battery and energy efficiency programs available
Check your eligibility with your solar installer — they’ll guide you through the process.
4. Will solar still work on cloudy or rainy days? ☀️
Yes, solar panels still generate electricity in cloudy weather — just at 40–70% efficiency compared to sunny conditions. You won’t get full output, but modern systems are designed to perform across varying light levels.
5. What size solar system do I need for my home? ☀️
This depends on your:
Average daily usage (in kWh)
Roof size and shading
Whether you plan to add batteries or EVs later
For most households, a 6.6kW system with a 5kW inverter is ideal. Larger homes may need 10kW+ systems. Your installer should analyse your bill and future plans before recommending a size.
6. How long do solar panels last? ☀️
Most quality solar panels come with a 25-year performance warranty and last 25–30 years. Inverters typically last 10–15 years, and batteries 8–12 years depending on usage and brand.
7. Do I need council approval to install solar? ☀️
In most cases, no council approval is needed for rooftop solar systems, especially under 10kW.
However:
If your home is heritage-listed
Or part of a body corporate or apartment complex you may need additional permissions.
8. How do I choose a reliable solar company? ☀️
Look for:
Clean Energy Council (CEC)-accredited installers
Transparent quotes with no hidden costs
Solid warranties on panels, inverter, and workmanship
Good reviews and after-sales service
