A Geelong commercial solar quote begins 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 North Geelong and Lara sheds at the low end.
The building then moves the Geelong number. Tilt frames on a Little Malop Street or waterfront 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 dock booking; a Colorbond roof on a Breakwater or Grovedale unit takes the same panels with a hoist. Older boards in the bluestone wool stores and the Pakington Street shopfronts add a switchboard upgrade at $1,500–$5,000.
Systems over 30 kW may carry network upgrade or connection works at $2,000–$10,000, and commercial panel cleaning once the array is running costs $5–$15 a panel. All prices include GST.

Worked Commercial Solar Cost Scenarios — Geelong
Three Geelong jobs priced from the rows above: a Lara logistics shed, a central Geelong office and a Bellarine winery. Each line names its row; the quote you get prices your own roof, board and connection.
Lara logistics shed. A freight operator at Lara fits 100 kW to a new tilt-slab warehouse at $70,000–$110,000, with $88,000 typical. Over 30 kW, 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.
Central Geelong office. The owner of a three-storey office near Little Malop Street installs 30 kW on tilt frames at $22,000–$33,000. The concrete roof gets a structural engineering report at $800–$2,000 before the frames are fixed, and the main switchboard is upgraded at $1,500–$5,000 to accept the inverter.
Bellarine winery upkeep. A cellar door near Drysdale runs a 20 kW array installed at $15,000–$26,000 across the winery shed and books commercial panel cleaning at $5–$15 a panel after vintage, when dust from the vineyard tracks and salt from the bay have settled on the glass.

Commercial Solar Costs by Sector in Geelong
Geelong commercial solar reaches from the industrial estates at North Geelong, Corio and Lara, through Breakwater, Moolap and Grovedale, to central Geelong and waterfront offices, retail on Pakington Street and Little Malop Street, the Waurn Ponds and Torquay precincts, and the farms and vineyards of the Bellarine and the Surf Coast hinterland.
North Geelong, Corio and Lara sheds - Manufacturing and logistics 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.
Breakwater, Moolap and Grovedale units - 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.
Central Geelong and waterfront 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.
Pakington Street, Torquay and Ocean Grove retail - A cafe, bar or surf shop fits a 10 kW system at $8,000–$12,000; the older Pakington Street shopfronts and converted wool stores are where a switchboard upgrade at $1,500–$5,000 joins the quote, and the coast calls for marine-grade clamps.
Bellarine and Surf Coast growers - Cellar doors, packing sheds and coolrooms 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 vintage.
What a Compliant Commercial Solar Quote Includes — Cost in Geelong
Before comparing Geelong 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
A structural engineering report, priced at $800–$2,000, listed as included or excluded
Switchboard upgrade work, at $1,500–$5,000 where needed, shown as its own line
For systems over 30 kW, network upgrade or connection works at $2,000–$10,000 and who lodges the network application
Crane or cherry picker hire at $1,000–$3,000 a day, and any lift, dock or after-hours access charges for towers
Commercial panel cleaning at $5–$15 a panel if a maintenance visit is bundled, priced per visit
Install, site works and any monitoring or maintenance each on its own line, on a single GST basis

Commercial solar cost in Geelong: Corio sheds, waterfront offices and Bellarine farms
A Geelong 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. Manufacturers and logistics operators 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 a Geelong quote. New sheds at Lara and Corio have clean metal decks and modern three-phase boards, so the quote stays close to the system price. Central Geelong and waterfront offices 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. The converted wool stores and the older shopfronts of Pakington Street and Geelong West 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 Geelong quote look for the STC line on its own, the name of whoever 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 priced per visit.
Commercial solar cost by system size in Geelong
Quick answerGeelong pricing steps by kilowatts: a Pakington Street cafe or Torquay surf shop sits in the $8,000–$12,000 10 kW bracket, a Grovedale workshop or Bellarine cellar door at 20 kW to 30 kW pays $15,000–$26,000 to $22,000–$33,000, and a Lara or Corio shed at 50 kW to 100 kW pays $35,000–$55,000 to $70,000–$110,000.
A larger Geelong array lowers the per-watt figure, $0.70–$1.20 across the range with the 100 kW Lara and Corio 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 Geelong job of any size. Waterfront offices need crane or cherry picker hire at $1,000–$3,000 a day plus dock and lift slots; bayside and Surf Coast sites at Eastern Beach, Torquay and Ocean Grove need fixings rated for salt air and the wind. 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 Geelong
What is the price of commercial solar in Geelong?
From our Geelong 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 Geelong?
A 30 kW commercial solar system in Geelong costs $22,000–$33,000 installed after STCs, with $27,000 typical. A central Geelong 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 Bellarine packing shed on a metal roof usually needs neither.
What does a 100 kW commercial solar system cost in Geelong?
Going by our Geelong table, expect $70,000–$110,000 for a 100 kW commercial system installed after STCs; the typical price is $88,000. North Geelong, Corio and Lara sheds are the usual Geelong 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 Geelong?
$0.70–$1.20 per watt installed after STCs on our Geelong 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 Geelong 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 the converted wool stores and the older shopfronts of Pakington Street and Geelong West. 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 Geelong need a structural engineering report?
A structural engineering report costs $800–$2,000 on our Geelong table, typically $1,200. Owners of central Geelong and waterfront office buildings usually ask for one before tilt frames go onto a concrete roof; a single-storey metal unit at Breakwater rarely needs it.
What does commercial solar panel cleaning cost in Geelong?
Commercial panel cleaning in Geelong costs $5–$15 a panel, with $10 a panel typical. Bayside and Surf Coast sites at Eastern Beach, Torquay and Ocean Grove, and Bellarine wineries after vintage, book it more often; have the quote price it per visit.
Do Geelong 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 Geelong quote and check the panel and inverter models against the listed products.
