Plan your install scope.

GridGirl maps your roof, shading, switchboard and system size into a structured brief installers can quote against. Takes about 3 minutes. No installer contact yet — that's a separate explicit step at the end.

Tell us about your roof

Roof type and orientation drive system sizing + installation complexity. Don't stress about exact numbers — your installer will verify on-site.

Roof type

Which orientation gets the most sun?

In Perth, north-facing rooftops produce ~10-20% more energy than east/west. South-facing is workable with a larger system.

Why scope before quotes?

· Your installer turns up already knowing your setup, so there's less back-and-forth
· You spot the gotchas early (an old switchboard, single-phase limits, feed-in caps), before you're deep in a quote process
· Your scope brief stays with you — pull it up next time, or share with a builder/sparkie for a second opinion
· No installers are contacted until you explicitly accept on the consent screen at the end of /get-quote
