Buying solar and a battery together can simplify hybrid design, monitoring and backup planning — especially while the Cheaper Home Batteries Program offers roughly $372 per usable kWh off eligible storage (since 1 July 2025). This service hub helps Australian households compare CEC-accredited solar-and-battery installers on usable capacity, STC pass-through, export limits and switchboard scope. MrSolar gathers up to three written package quotes so you can judge the whole energy system, not two disconnected invoices.

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?
A single hybrid ecosystem reduces orphaned inverters and duplicate labour. You also align warranties and app monitoring. Piecemeal still works for some retrofits — packages shine for new installs and major upgrades. If two quotes disagree on “Why packages can beat piecemeal upgrades”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Why packages can beat piecemeal upgrades” point for solar and battery installers Australia, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /services/solar-and-battery.
Panel/inverter STCs should appear separately from the battery usable-kWh subsidy. If a quote blends everything into one mysterious “gov rebate,” ask for a breakdown with zone, deeming years and usable kWh. Because solar and battery decisions are site-specific, use monitoring or bill interval data where you have it, then ask each CEC-accredited installer to reconcile their design to those facts. If two quotes disagree on “Split the incentives on the quote”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
Oversizing batteries for rarely used backup is expensive even with subsidies. Match usable kWh to typical 4pm–10pm consumption, then decide if backup circuits are worth extra hardware. Because solar and battery decisions are site-specific, use monitoring or bill interval data where you have it, then ask each CEC-accredited installer to reconcile their design to those facts. If two quotes disagree on “Size storage to evening kWh, panels to daytime load”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
When DNSPs limit export, combined systems capture surplus that FiTs undervalue. Require the expected export limit on each proposal before you celebrate modelled savings. Because solar and battery decisions are site-specific, use monitoring or bill interval data where you have it, then ask each CEC-accredited installer to reconcile their design to those facts. If two quotes disagree on “Export-constrained suburbs”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
Whole-home backup differs from essential-circuits backup. Changeover equipment, surge loads (ducted AC, pumps) and black-start behaviour must be scoped explicitly. Homeowners comparing Solar and Battery Installers Australia — Combined Package Quotes should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Backup and blackout expectations”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
VIC, QLD, SA and ACT battery supports may stack or interact with federal discounts under specific rules. Eligibility windows move — treat state dollars as provisional until confirmed. Because solar and battery decisions are site-specific, use monitoring or bill interval data where you have it, then ask each CEC-accredited installer to reconcile their design to those facts. If two quotes disagree on “State program stacking”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
We match CEC-accredited installers who deliver combined systems. Normalise panel kW, usable battery kWh, backup scope and net price after incentives. Because solar and battery decisions are site-specific, use monitoring or bill interval data where you have it, then ask each CEC-accredited installer to reconcile their design to those facts. If two quotes disagree on “Compare three package quotes via MrSolar”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
