How to Compare Solar Quotes
With multiple solar companies offering different products and pricing. Before installing rooftop system, compare several Australian solar quotes to find the best value and warranty coverage for your home or business solar system.
Here’s how to compare quotes effectively:
Total Cost & Payment Options
Compare the total cost (fully installed) and break down what’s included (e.g., installation, permits, warranties). Some quotes offer interest-free finance, rebates, or flexible payment terms—factor these in.
Warranty & After Sales Support
A good quote should include warranties on panels (usually 25 years), inverters (10 years), and installation (varies by company). The longer the warranty, the more confidence the provider has in their product.
System Size and Output
Check the kilowatt (kW) size of each system. Compare estimated annual energy production (kWh) to match your electricity needs. Ensure the quote accounts for your location’s sunlight exposure.
Look Beyond the Price
While price is important, the cheapest solar panels aren’t always the best investment. To ensure long-term savings and reliability, consider these 5 crucial factors before making your decision.
Compare Panel & Inverter Brands
Look for high-quality, CEC-approved brands with strong warranties. Research brands listed in each quote—panels should have a 25-year performance warranty, and inverters at least 10 years.
Installation Timeline
A quick turnaround might be important. Check the estimated installation time, how soon work can begin, and if any site inspections are included. A fast install doesn’t mean it’s rushed—ask about quality control.

- Get at least three quotes from different providers for comparison.
- Check reviews and testimonials of the solar company.
- Confirm they use Clean Energy Council (CEC)-approved products for safety and efficiency.
- Ask about rebates and feed-in tariffs to maximize savings.
- Look for local installers who understand your area’s solar regulations.
