Commercial solar pays when it offsets expensive daytime tariffs and demand charges — not when it chases tiny feed-in rates. Australian businesses in 2026 still access Small-scale Technology Certificates on eligible system sizes, while larger sites move into different certificate and network pathways. MrSolar connects you with CEC-accredited commercial installers who can model interval data, roof loading and DNSP applications, then deliver up to three comparable 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?
Warehouses, cold storage, retail with long open hours, manufacturers and offices with weekday peaks usually win. If your load coincides with sunshine, self-consumption dominates ROI. Export-heavy designs on low FiTs are weaker unless a battery or VPP pathway is intentional. Homeowners comparing Commercial Solar Australia — Compare CEC-Accredited Business 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 “Where commercial solar creates the most value”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
Many SME rooftop systems still sit inside the small-scale framework and receive STCs similar to residential logic (size × zone × deeming). Larger plants may create Large-scale Generation Certificates instead. Ask installers which scheme applies and to show the math. Battery subsidies aimed at homes (Cheaper Home Batteries Program ~$372/kWh usable) may not map cleanly to commercial eligibility — verify before baking them into board papers.
Three-phase capacity, export limits, protection settings and metering upgrades can gate energisation for months if ignored. Name your distributor early (Ausgrid, Energex, Powercor, Western Power, etc.) and require the application pathway on every quote. After install, revisit “DNSP applications are a critical path item” using your app’s import/export charts — that feedback loop is how commercial solar stays aligned with real tariffs and DNSP behaviour. Because commercial solar 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.
Small sites often land 15–50kW; mid sites 50–200kW; larger rooftops beyond that. Use twelve months of interval data where possible. Roof membrane warranties, structural reports and WHS access plans belong in serious commercial proposals.

Specify monitoring portals, alert responsiblity, cleaning assumptions and whether a performance guarantee exists. Commercial assets need documented O&M more than residential arrays do. If two quotes disagree on “O&M, monitoring and performance guarantees”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “O&M, monitoring and performance guarantees” point for commercial solar, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /services/commercial-solar.
Cash, equipment finance and PPA-style offers change who owns STCs and who books the savings. Align legal review with technical scope so certificate assignment is explicit. Because commercial solar 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 “Financing and procurement tips”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
Submit site details and we introduce up to three CEC-accredited commercial installers. Compare like-for-like kW, products, network fees and incentive assumptions before you take a proposal to finance. MrSolar’s three-quote flow for commercial solar exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure.
