Decision framework

How to think about solar properly

Bad solar decisions usually come from focusing on the wrong headline number. A cheap quote can be expensive if the equipment, installation quality or savings assumptions are weak.

01

Start with usage

Your electricity usage pattern matters. A home using more electricity during daylight hours will usually benefit more from solar.

02

Check roof suitability

Orientation, shading, roof angle, available space and roof condition all affect system performance.

03

Compare assumptions

Do not trust payback estimates unless you understand electricity price assumptions, export rates and degradation.

04

Inspect the warranty

Panel, inverter, battery and workmanship warranties are different. Check who backs each one and for how long.

Use the knowledge hub before comparing solar quotes

Solar can be a strong home upgrade, but only when the system is designed around your roof, usage, tariff and budget. Learn the basics first, then compare quotes with a sharper eye.
