A Canberra commercial solar quote starts with kilowatts: $8,000–$12,000 for a 10 kW system on a small shop or office, $15,000–$26,000 for 20 kW, $22,000–$33,000 for 30 kW, $35,000–$55,000 for 50 kW and $70,000–$110,000 for 100 kW, all installed after STCs. Per watt the range is $0.70–$1.20, with the wide Hume and Majura Park sheds at the low end.
The building then moves the Canberra number. Tilt frames on a Civic or Barton office roof need a structural engineering report at $800–$2,000, crane or cherry picker hire at $1,000–$3,000 a day and a loading-dock booking; a flat Colorbond roof on a Mitchell or Fyshwick unit takes the same panels with a hoist. Older boards in Fyshwick's original showrooms and Queanbeyan's main-street shops add a switchboard upgrade at $1,500–$5,000.
Over 30 kW, network upgrade or connection works at $2,000–$10,000 may be added, and commercial panel cleaning after the install costs $5–$15 a panel. Prices include GST.

Worked Commercial Solar Cost Scenarios — Canberra
Three Canberra examples priced from this page's rows: a Hume distribution shed, a Barton office building and a Pialligo nursery. Each line names the row it draws on; the quote you receive prices your own roof and board.
Hume distribution shed. A wholesaler in Hume fits 100 kW to a long north-facing shed roof at $70,000–$110,000, with $88,000 typical. Being over 30 kW, the network upgrade or connection works are quoted on their own line at $2,000–$10,000, and a crane at $1,000–$3,000 a day lifts the panel pallets.
Barton office building. The owner of a three-storey Barton office installs 30 kW on tilt frames at $22,000–$33,000. The concrete roof gets a structural engineering report at $800–$2,000 first, and the base-building switchboard is upgraded at $1,500–$5,000 to take the inverter.
Pialligo nursery upkeep. A nursery at Pialligo runs a 20 kW array installed at $15,000–$26,000 across the glasshouse shed and books commercial panel cleaning at $5–$15 a panel each spring, once the winter frosts and the pollen season are done.

Commercial Solar Costs by Sector in Canberra
Canberra commercial solar covers the industrial estates at Hume, Fyshwick, Mitchell and Majura Park, Queanbeyan's workshops, office buildings in Civic, Barton and Belconnen, retail in Braddon, Kingston and Manuka, and the nurseries, orchards and vineyards of Pialligo and Murrumbateman.
Hume and Majura Park sheds - Distribution and airport-precinct roofs take 100 kW arrays at $70,000–$110,000, the size at which the installed cost per watt sits nearest the $0.70 floor of $0.70–$1.20.
Fyshwick, Mitchell and Queanbeyan units - Showrooms, workshops and trade units buy 30 kW to 50 kW at $22,000–$33,000 to $35,000–$55,000; over 30 kW they carry network upgrade or connection works at $2,000–$10,000.
Civic, Barton and Belconnen offices - Tilt frames over concrete need a structural engineering report at $800–$2,000 and crane or cherry picker hire at $1,000–$3,000 a day, on top of a 20 kW or 30 kW system at $15,000–$26,000 or $22,000–$33,000.
Braddon, Kingston and Manuka retail - A cafe, bar or shop fits a 10 kW system at $8,000–$12,000; the older shopfronts in Kingston and Queanbeyan are where a switchboard upgrade at $1,500–$5,000 joins the quote.
Pialligo and Murrumbateman growers - Nursery sheds, coolrooms and cellar doors run 30 kW to 50 kW at $22,000–$33,000 to $35,000–$55,000, with commercial panel cleaning at $5–$15 a panel after the pollen and dust seasons.
What a Compliant Commercial Solar Quote Includes — Cost in Canberra
Before comparing Canberra quotes, check each one prices the same kilowatts and the same panel and inverter brands, states how the installer gets panels and people onto the roof, and shows site works, certificates and GST on their own lines.
System size in kW, panel count, panel and inverter make and model, and whether the inverter is single or three phase
The STC assignment shown as a separate line, so the installed price after STCs and the price before it are both visible

Commercial solar cost in Canberra: Hume sheds, Civic offices and Pialligo growers
A Canberra small business starts at $8,000–$12,000 for a 10 kW system installed after STCs (typically $10,000), then $15,000–$26,000 for 20 kW and $22,000–$33,000 for 30 kW. Distribution and trade businesses buy 50 kW at $35,000–$55,000 and 100 kW at $70,000–$110,000, and those arrays are what take the installed cost per watt to the floor of $0.70–$1.20.
The roof then writes the rest of the Canberra quote. New sheds at Hume and Majura Park have clean metal decks and modern three-phase boards, so the quote stays close to the system price. Offices in Civic, Barton and Belconnen put panels on tilt frames over concrete, bringing a structural engineering report at $800–$2,000, crane or cherry picker hire at $1,000–$3,000 a day and a dock booking. Fyshwick's original showrooms and the older Queanbeyan and Kingston shopfronts are where a switchboard upgrade at $1,500–$5,000 most often appears.
The Clean Energy Regulator says eligibility for solar PV systems under the Small-scale Renewable Energy Scheme has been expanded from 100 kW to 1 MW for eligible systems installed from 1 October 2026, with a fixed 5-year deeming period for 100 kW to 1 MW systems, and that STC applications for those mid-scale systems will not open until mid to late November 2026. Existing arrangements for systems smaller than 100 kW are not affected. On a Canberra quote check that the STC line stands on its own, the installer names who lodges the network application on a system over 30 kW, where $2,000–$10,000 of connection works can apply, and commercial panel cleaning at $5–$15 a panel is priced per visit.
Commercial solar cost by system size in Canberra
Quick answerCanberra pricing steps by kilowatts: a Braddon cafe or Manuka shop sits in the $8,000–$12,000 10 kW bracket, a Mitchell workshop or Murrumbateman cellar door at 20 kW to 30 kW pays $15,000–$26,000 to $22,000–$33,000, and a Hume or Majura Park shed at 50 kW to 100 kW pays $35,000–$55,000 to $70,000–$110,000.
A larger Canberra array lowers the per-watt figure, $0.70–$1.20 across the range with the 100 kW Hume sheds at the bottom. Fixed items do not scale: a structural engineering report at $800–$2,000 costs much the same at 20 kW or 50 kW, and a switchboard upgrade at $1,500–$5,000 depends on the board's age rather than the array.
Access and weather are the other levers on a Canberra job of any size. Civic and Barton offices need crane or cherry picker hire at $1,000–$3,000 a day plus dock and lift slots, and winter frosts shorten the install window on the exposed Hume roofs. Over 30 kW the network upgrade or connection works line at $2,000–$10,000 appears, and commercial panel cleaning at $5–$15 a panel is the running cost at every size.
Frequently Asked Questions — Commercial Solar Cost in Canberra
What is the price of commercial solar in Canberra?
From our Canberra table: $8,000–$12,000 for a 10 kW commercial system (typically $10,000); $22,000–$33,000 for a 30 kW system (typically $27,000); $70,000–$110,000 for a 100 kW system (typically $88,000), all installed after STCs.
How much does a 30 kW commercial solar system cost in Canberra?
A 30 kW commercial solar system in Canberra costs $22,000–$33,000 installed after STCs, with $27,000 typical. A Barton tenancy on an office roof adds a structural engineering report at $800–$2,000 and crane or cherry picker hire at $1,000–$3,000 a day; a Pialligo nursery shed on a metal roof usually needs neither.
What does a 100 kW commercial solar system cost in Canberra?
Going by our Canberra table, expect $70,000–$110,000 for a 100 kW commercial system installed after STCs; the typical price is $88,000. Hume and Majura Park sheds are the usual Canberra buyers, and network upgrade or connection works at $2,000–$10,000 are priced on top because the system is over 30 kW.
What is the installed cost per watt for commercial solar in Canberra?
$0.70–$1.20 per watt installed after STCs on our Canberra table, with $0.90 typical. The larger the array the lower the figure: a 100 kW system at $70,000–$110,000 sits near the floor, a 10 kW system at $8,000–$12,000 near the top.
Does a Canberra business need a switchboard or network upgrade for solar?
Often one or both. A switchboard upgrade for a commercial system costs $1,500–$5,000 and is common in Fyshwick's original showrooms and the older shopfronts of Kingston and Queanbeyan. Network upgrade or connection works at $2,000–$10,000 apply to systems over 30 kW, so ask the installer to show the line and name who lodges the network application.
What changed for commercial solar systems over 100 kW?
The Clean Energy Regulator says the Renewable Energy (Electricity) Regulations 2001 have been amended to expand eligibility for solar PV systems under the Small-scale Renewable Energy Scheme from 100 kW to 1 MW, applying to eligible mid-scale systems installed from 1 October 2026, with a fixed 5-year deeming period; STC applications for mid-scale systems will not open until mid to late November 2026. Existing arrangements for systems smaller than 100 kW are not affected.
Does a commercial solar install in Canberra need a structural engineering report?
A structural engineering report costs $800–$2,000 on our Canberra table, typically $1,200. Owners of Civic, Barton and Belconnen office buildings usually ask for one before tilt frames go onto a concrete roof; a single-storey metal unit in Mitchell rarely needs it.
What does commercial solar panel cleaning cost in Canberra?
Commercial panel cleaning in Canberra costs $5–$15 a panel, with $10 a panel typical. Pialligo and Murrumbateman growers after the pollen and dust seasons book it more often; have the quote price it per visit.
Do Canberra commercial solar installers need accreditation?
For mid-scale systems of 100 kW to 1 MW, the Clean Energy Regulator says the system must have its panels, batteries or inverters listed on the Clean Energy Council list of approved components and meet Solar Accreditation Australia install guidelines. Ask for the accreditation number on your Canberra quote and check the panel and inverter models against the listed products.
