Book a solar survey

Quick solar investment checker

A fast way to see whether solar could be a smart investment for your home.

This calculator is designed to give homeowners a quick, transparent view of likely solar performance, annual value and simple payback before booking a survey. [page:1]

  • Use postcode to estimate location-based generation. [web:44][web:58][web:59]
  • Estimate panel count from a simple roof-size choice. [web:62]
  • Turn generation into savings using the same self-use and export split described on the source page. [page:1]
  • Show a clear verdict instead of overwhelming users with too many variables. [page:1]

What usually makes solar a better investment?

01

Generation

Good generation at your location improves the total annual value of your system.

02

Self-use

Using more of the electricity you generate increases savings at your normal import rate.

03

Battery value

A battery can increase self-consumption where its extra annual benefit supports the additional cost.

04

Payback

A shorter payback period usually indicates a stronger solar investment opportunity.
