Solar quotes are packed with jargon: STCs, DNSP, hybrid inverters, usable kWh, export limits and more. This glossary translates the terms Australian homeowners meet in 2026 proposals so you can interrogate CEC-accredited installers with confidence. Pair definitions with MrSolar’s guides and quote comparison flow — understanding the words is step one to avoiding expensive misunderstandings.
Tell us about your home. We'll match you with 3 local installers.
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?

STC (Small-scale Technology Certificate): tradeable certificate that usually becomes an upfront solar discount. Deeming period: years of future generation counted in the STC formula. Cheaper Home Batteries Program: federal battery discount available since 1 July 2025, commonly planned near $372/kWh usable. Point-of-sale discount: incentive applied on the invoice rather than a later rebate cheque.
DNSP: your distribution network service provider (Ausgrid, Energex, SAPN, etc.). NMI: meter identifier. Export limit: maximum kW you may send to the grid. FiT: feed-in tariff paid for exports — often only a few c/kWh. Pre-approval: network permission required before install in markets like South Australia. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Grid and network terms”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “Grid and network terms” using your app’s import/export charts — that feedback loop is how solar glossary stays aligned with real tariffs and DNSP behaviour.
kW vs kWh: power versus energy. Hybrid inverter: manages panels and battery. Usable capacity: battery energy you can actually discharge. CEC-listed: product appears on Clean Energy Council approved lists. String vs microinverter: central versus per-panel conversion architectures. If two quotes disagree on “Hardware vocabulary”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Hardware vocabulary” point for solar glossary, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-glossary.
Peak sun hours: equivalent full-sun hours used in yield planning. Self-consumption: solar energy used on-site. Clipping: inverter AC limit wasting some DC peaks. Orientation/azimuth and tilt: roof geometry that changes yield. Performance ratio: real output versus ideal. Keep Epic Unicorn Pty Ltd / MrSolar matching separate from installer contracts: accreditation and incentive claims must appear on the installer’s paperwork for /solar-glossary. Homeowners comparing Solar Glossary Australia — Clear Definitions for Buyers 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.
CEC accreditation: required credentials for incentive-eligible installs. Energisation: permission to operate after inspection/paperwork. Workmanship warranty: installer labour cover distinct from product warranty. STS/switchboard upgrade: electrical board work sometimes needed for new capacity.

When a proposal uses a term you cannot map to a number — especially STC dollars, usable kWh or export kW — pause and ask for the figure. MrSolar’s three-quote process works best when every party speaks the same definitions. Homeowners comparing Solar Glossary Australia — Clear Definitions for Buyers 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 “How to use this glossary with quotes”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
After definitions, read the rebates hub, calculator tools and service pages. Then request CEC-accredited quotes. Glossary literacy plus written scope beats brochure optimism. If two quotes disagree on “Keep learning on MrSolar”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Keep learning on MrSolar” point for solar glossary, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-glossary.
