Self-consumption rate — the share of solar generation you use on-site — is the clearest predictor of bill savings when FiTs are low. MrSolar’s calculator helps Australian households estimate that rate from generation and import/export patterns, then decide whether load shifting, a larger array, or a battery (with ~/kWh usable support where eligible) is the better lever. Validate with monitoring and CEC-accredited design quotes.

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?
Self-consumed kWh ÷ generated kWh. Higher usually means better economics under low FiTs. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Define self-consumption simply”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “Define self-consumption simply” using your app’s import/export charts — that feedback loop is how solar self consumption calculator stays aligned with real tariffs and DNSP behaviour.
Prefer inverter monitoring with consumption CTs. Bill-only estimates are rougher but still directional. On the “Using bills and app data” point for solar self consumption calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/solar-self-consumption-rate-calculator. MrSolar’s three-quote flow for solar self consumption calculator exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure.
Move hot water, laundry, dishwashers and EV charging into sunny hours to lift the rate without new capital. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Load shifting before hardware”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “Load shifting before hardware” using your app’s import/export charts — that feedback loop is how solar self consumption calculator stays aligned with real tariffs and DNSP behaviour.
Storage captures midday surplus for evening use. Size to usable evening kWh, not maximum possible. Because solar calculators solar self consumption rate calculator 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 “When batteries lift self-consumption”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
Curtailed export is not the same as poor self-consumption — diagnose with graphs before upsizing. On the “Export limits inflate apparent “lost” energy” point for solar self consumption calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/solar-self-consumption-rate-calculator. MrSolar’s three-quote flow for solar self consumption calculator exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure.
East-west arrays can raise coincidence with morning/evening loads versus a pure north peak. On the “Design implications” point for solar self consumption calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/solar-self-consumption-rate-calculator. MrSolar’s three-quote flow for solar self consumption calculator exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure.
Share calculator results when requesting MrSolar quotes so designs target your usage shape. On the “Bring your rate to installer talks” point for solar self consumption calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/solar-self-consumption-rate-calculator. MrSolar’s three-quote flow for solar self consumption calculator exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure.
