A solar quote that only shouts a dollar-per-watt figure is incomplete. Australian households should expect itemised hardware, soft costs, approvals, and assumptions — the same discipline you would apply to a major renovation quote.
Hardware identity, not vague brands
Panel model and wattage, inverter model, optimiser or microinverter counts, mounting system, and battery model if included should be named. “Tier-1 panels” is not a line item.
| Line item | Why it belongs | Red flag if missing |
|---|---|---|
| STC discount | Defines net capital | Cannot compare net price |
| Scaffold / roof access | Common soft cost | Surprise invoice later |
| Switchboard works | Often required | Hidden electrical risk |
| Meter / connection fees | Network pathway | Timeline and cost drift |
| Export limit assumption | Shapes yield | Optimistic generation |
| Warranty labour terms | Aftercare cost | Parts-only surprises |
- Demand the same itemisation from every bidder
- Separate optional extras clearly
- Note validity dates and panel stock caveats
- Include who lodges distributor paperwork
If it is not on the quote, it is on you later.
Payment schedule
Deposits, delivery, install, and commissioning stages should be written. Large upfront payments for unverified companies are avoidable risk.
Exclusions list
Good quotes also list what is not included — asbestos roof works, heritage fees, trenching to sheds. Exclusions are clarity, not hostility.
