Solar Quotes for Australian Homes
Understanding what’s in a solar quote - and how to compare them - is the difference between a great deal and an expensive mistake. Here’s everything you need to know, from what drives the price to the red flags that should make you walk away.
What’s in a solar quote
A legitimate solar quote from a CEC-accredited installer should include all of these line items. If something is missing, ask before you sign.
| Line item | What to check |
|---|---|
| Panels | Brand, wattage, quantity, efficiency rating, product & performance warranty |
| Inverter | Brand, model, capacity (kW), warranty period |
| Installation | Labour, roof mounting hardware, AC/DC cabling, isolators |
| STC rebate | Deducted from your invoice - already applied in most quotes |
| Grid connection | Network application fee (some installers include, some don't) |
| Monitoring | App-based system - often included, ask if not mentioned |
| Workmanship warranty | 10 years is standard from reputable installers |

How to compare solar quotes
Most homeowners compare solar quotes on price alone. Here’s what you should actually check.
- Compare the same system size (kW) - not just price
- Check the panel model and wattage, not just the brand name
- Confirm the inverter brand and capacity matches your system
- Verify workmanship warranty length and who backs it
- Ask whether grid connection fee is included
- Confirm the STC rebate is already deducted (most reputable installers do this)
- Check if monitoring app is included at no extra cost
- Ask whether the installer uses their own employees or subcontractors

Solar quote red flags
These seven warning signs appear regularly in complaints to state fair trading offices. If you spot any, get another quote before committing.
No CEC accreditation
Required to claim government rebates. No accreditation = no STCs.
Price too low by 30%+
Usually means substandard panels, no warranty support, or unlicensed labour.
Verbal quote only
Written quotes are legally required. No paper trail = no protection.
High-pressure same-day deadline
Quality installers don't need you to decide before they leave.
STC rebate quoted separately
Rebates should already be deducted. Quoting them as a 'bonus' is misleading.
No workmanship warranty mentioned
10 years is industry standard. Shorter or absent means higher risk.
Can't provide recent local references
Good installers have satisfied customers willing to be contacted.
