Takes about a minute to start. OVO handles quote details and suitability checks.
This checklist is for comparing assumptions behind solar quotes. It is useful before you speak to an installer and again before you sign.
Roof and system
Direction, shade, panel count and total kWp.
Money and tariff
Installed cost, import price, export rate and battery cost.
Real life
Daytime use, future electricity demand and how confident you are in each estimate.
Copy this into your quote notes
For each quote, write down the assumptions in the same order. Missing answers are not automatically bad, but they are questions to ask.
- System size
- Annual generation
- Self-use percentage
- Export price
- Import price
- Battery size
- Degradation
- Maintenance or inverter replacement allowance
Use the checklist to slow the decision down
A good solar decision should feel clearer after questions, not more rushed.
