Hobart commercial solar is priced by system size: $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, installed after STCs. Per watt that is $0.70–$1.20, with the long sheds at Brighton and Cambridge at the low end.
The building then shapes the Hobart quote. Tilt frames on a Macquarie Street or Collins Street 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 street-closure or dock booking; a Colorbond roof on a Derwent Park or Kingston unit takes the same panels with a hoist. Sandstone warehouses at Salamanca and older shopfronts in North Hobart add a switchboard upgrade at $1,500–$5,000 when the board cannot take an inverter.
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 — Hobart
Three Hobart jobs priced from the rows above: a Brighton transport depot, a Hobart CBD office and a Huon Valley packing shed. Each line names its row; the quote you get prices your own roof, board and connection.
Brighton transport depot. A freight company at the Brighton hub fits 100 kW to a long shed roof 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 lands the panel pallets.
Hobart CBD office. The owner of a four-storey Collins Street office 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 go up, and the main switchboard is upgraded at $1,500–$5,000 to accept the inverter.
Huon Valley packing shed upkeep. An apple grower in the Huon Valley runs a 20 kW array installed at $15,000–$26,000 over the packing shed and books commercial panel cleaning at $5–$15 a panel after harvest, when orchard dust and lichen have built up on the glass.

Commercial Solar Costs by Sector in Hobart
Hobart commercial solar runs from the northern industrial strip at Derwent Park, Moonah and Glenorchy, through the Brighton transport hub and the Cambridge airport estate, to CBD offices on Macquarie and Collins streets, Salamanca and Battery Point hospitality, Sandy Bay and Kingston retail, and the orchards and vineyards of the Huon and Coal River valleys.
Brighton and Cambridge sheds - Transport and airport-estate 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.
Derwent Park, Moonah and Kingston 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.
CBD offices - Tilt frames over concrete on Macquarie and Collins streets 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.
Salamanca, North Hobart and Sandy Bay retail - A cafe, bar or shop fits a 10 kW system at $8,000–$12,000; the sandstone warehouses at Salamanca and the older North Hobart shopfronts are where a switchboard upgrade at $1,500–$5,000 joins the quote.
Huon and Coal River valley growers - Packing 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 harvest.
What a Compliant Commercial Solar Quote Includes — Cost in Hobart
Before comparing Hobart 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

Commercial solar cost in Hobart: Brighton sheds, CBD offices and valley orchards
For a Hobart small business the starting point is $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. Transport and processing sites buy 50 kW at $35,000–$55,000 and 100 kW at $70,000–$110,000, and those arrays take the installed cost per watt to the floor of $0.70–$1.20.
The roof writes the rest of a Hobart quote. New sheds at Brighton and Cambridge have clean metal decks and modern three-phase boards, so the quote stays close to the system price. CBD offices put panels on tilt frames over concrete, which brings a structural engineering report at $800–$2,000, crane or cherry picker hire at $1,000–$3,000 a day and a dock or street booking. Salamanca's sandstone warehouses and the older shopfronts of North Hobart and Moonah are where a switchboard upgrade at $1,500–$5,000 is most often needed.
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 Hobart 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 Hobart
Quick answerHobart pricing steps by kilowatts: a Salamanca cafe or Sandy Bay shop sits in the $8,000–$12,000 10 kW bracket, a Moonah workshop or Coal River cellar door at 20 kW to 30 kW pays $15,000–$26,000 to $22,000–$33,000, and a Brighton or Cambridge shed at 50 kW to 100 kW pays $35,000–$55,000 to $70,000–$110,000.
A bigger Hobart array buys a lower per-watt price, $0.70–$1.20 across the range with the 100 kW Brighton sheds at the bottom. Fixed items do not move with size: a structural engineering report at $800–$2,000 is much the same at 20 kW or 50 kW, and a switchboard upgrade at $1,500–$5,000 depends on the board's age, not the array.
Access and weather are the other levers on a Hobart job of any size. CBD offices need crane or cherry picker hire at $1,000–$3,000 a day plus dock and lift slots; Derwent-side and Kingston Beach sites need fixings rated for salt air, and winter shortens the install window. 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 Hobart
What is the price of commercial solar in Hobart?
From our Hobart 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 Hobart?
A 30 kW commercial solar system in Hobart costs $22,000–$33,000 installed after STCs, with $27,000 typical. A Collins Street 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 Huon Valley packing shed on a metal roof usually needs neither.
What does a 100 kW commercial solar system cost in Hobart?
Going by our Hobart table, expect $70,000–$110,000 for a 100 kW commercial system installed after STCs; the typical price is $88,000. Brighton and Cambridge sheds are the usual Hobart 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 Hobart?
$0.70–$1.20 per watt installed after STCs on our Hobart 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 Hobart 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 Salamanca's sandstone warehouses and the older shopfronts of North Hobart and Moonah. 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 Hobart need a structural engineering report?
A structural engineering report costs $800–$2,000 on our Hobart table, typically $1,200. Owners of CBD office buildings usually ask for one before tilt frames go onto a concrete roof; a single-storey metal unit at Derwent Park rarely needs it.
What does commercial solar panel cleaning cost in Hobart?
Commercial panel cleaning in Hobart costs $5–$15 a panel, with $10 a panel typical. Derwent-side sites and Huon and Coal River valley growers after harvest book it more often; have the quote price it per visit.
Do Hobart 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 Hobart quote and check the panel and inverter models against the listed products.
