Time-of-use (TOU) tariffs can amplify solar value when you shift loads into sunny off-peak/shoulder windows — or punish you if evenings dominate. MrSolar’s TOU versus flat-rate calculator helps Australian households compare bill outcomes with solar under both structures before locking a retailer plan. Pair insights with CEC-accredited system design, STC-aware pricing and optional batteries (~/kWh usable).

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?
Evening peaks without solar coincidence favour flat rates or batteries. Daytime-heavy homes often like TOU plus PV. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Map your usage to TOU windows”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “Map your usage to TOU windows” using your app’s import/export charts — that feedback loop is how TOU vs flat rate solar calculator stays aligned with real tariffs and DNSP behaviour.
A plan that won pre-solar can lose post-solar. Rerun comparisons after install using monitoring data. Homeowners comparing TOU vs Flat Rate Solar Savings Calculator 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 “Solar changes the optimal plan”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
Do not pick TOU solely for a slightly higher FiT if import peaks destroy the benefit. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “FiT lines are secondary”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “FiT lines are secondary” using your app’s import/export charts — that feedback loop is how TOU vs flat rate solar calculator stays aligned with real tariffs and DNSP behaviour.
Charge from solar, discharge into peak windows. Size usable kWh to the peak period you actually face. If two quotes disagree on “Batteries as a TOU tool”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Batteries as a TOU tool” point for TOU vs flat rate solar calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/time-of-use-vs-flat-rate-solar-savings-calculator.
Tariff shopping does not override DNSP caps. Design self-consumption regardless of plan. Because solar calculators time of use vs flat rate solar savings 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 “Export limits still apply”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
Keep assumption notes with dates. Retail offers change frequently. If two quotes disagree on “Use calculator outputs in retailer switches”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Use calculator outputs in retailer switches” point for TOU vs flat rate solar calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/time-of-use-vs-flat-rate-solar-savings-calculator.
If TOU + battery wins, request MrSolar quotes that include hybrid storage scope from CEC-accredited installers. MrSolar’s three-quote flow for TOU vs flat rate solar calculator exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure. Keep Epic Unicorn Pty Ltd / MrSolar matching separate from installer contracts: accreditation and incentive claims must appear on the installer’s paperwork for /solar-calculators/time-of-use-vs-flat-rate-solar-savings-calculator.
