● Solar for new-home builders · South East Queensland
Wholesale solar packages and upgrades for your selections process, with your own margin. We handle design, installation, STC paperwork and homeowner support.
Your selections
Standard solar kits, clear upgrades and sales materials ready for your client conversations.
Your pricing
Wholesale supply and installation pricing. You set your selling price and keep the builder relationship.
Your plans
Repeatable designs for your standard homes, or a tailored solar design for a custom build.
§ Coverage
We run install crews across South East Queensland and the Toowoomba region — sequenced to your roof-on calendar, not a national rollout schedule.
§ Process
From the selections conversation to homeowner handover, we work with your team through three stages.
Share your plans or tell us what you build. We reply within one business day to confirm next steps, then prepare a design, trade quote and upgrade options for your selections team.
We coordinate installation with your site team once the roof is on, with commissioning during final fit. Solar is integrated into the build, with timing confirmed for each project.
STC claim, electrical safety cert, grid energisation, warranty registration — bound into a single compliance pack. From handover, the homeowner calls us, not you.
