A grid-connect solar system works with your DNSP connection: you use rooftop generation first, export surplus under approved limits, and import at night. It is the default for Australian suburbs because it avoids large battery banks and generators. In 2026, “grid-connect” still means DNSP paperwork, STCs, CEC-accredited install — and optional batteries under federal ~$372/kWh usable support.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.
Free for homeowners. Participating installers pay MrSolar a lead fee when matched — that does not buy a higher ranking in our guides or reviews. See how we match quotes and is MrSolar legit?
Panels → inverter → house loads → export meter if surplus → import meter if shortfall. Net metering settlement and retailer FiTs sit on top of that physics. Blackout behaviour is limited unless backup hardware is added.
Grid-connect inverters must shut down when the grid fails so they do not energise lines for network workers. That safety feature is why standard solar alone does not keep your lights on in an outage.
Most residential grid-connect PV under 100kW creates STCs when CEC pathways and products align. Zone and deeming set the federal discount — about $1,435 for a Zone 3 6.6kW system at ~$39.85/STC (as of 5 August 2026).
Hybrids turn grid-connect homes into solar-plus-storage homes without going off-grid. Export limits often motivate earlier battery adoption. Keep the system grid-tied for reliability even when you self-consume heavily.
Older fuse boards, shared metering in flats, and three-phase supplies change scope. A cheap panel price that excludes switchboard works is incomplete. Insist on inclusions.
