Sunshine Coast commercial solar is priced by the kilowatt: $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 wide Kunda Park and Caloundra West sheds at the low end.
The building then moves a Sunshine Coast quote. Tilt frames on a Maroochydore CBD or Mooloolaba tower 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 Warana or Coolum industrial unit takes the same panels with a hoist. Older boards in Nambour's main-street shops and the Yandina sheds add a switchboard upgrade at $1,500–$5,000.
Anything 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, booked often on the beachfront. All prices include GST.

Worked Commercial Solar Cost Scenarios — Sunshine Coast
Three Sunshine Coast jobs priced from the rows above: a Kunda Park manufacturer, a Birtinya office building and a Glass House Mountains farm. Each line names its row; the quote you get prices your own roof, board and connection.
Kunda Park manufacturer. A joinery business at Kunda Park fits 100 kW to a long factory 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.
Birtinya office building. The owner of a three-storey office in the Birtinya health precinct 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 accept the inverter.
Glass House Mountains farm upkeep. A pineapple grower near Beerwah 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 the summer storms have left pollen and red dust on the glass.

Commercial Solar Costs by Sector in Sunshine Coast
Sunshine Coast commercial solar reaches from the industrial estates at Kunda Park, Warana, Caloundra West and Coolum, through the Yandina and Nambour sheds, to Maroochydore CBD and Birtinya offices, Mooloolaba and Noosa towers, retail on Hastings Street, Ocean Street and the Caloundra strip, and the farms and nurseries of the Glass House Mountains, Woombye and the Mary Valley.
Kunda Park, Warana and Caloundra West sheds - Manufacturing and distribution 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.
Coolum, Yandina and Nambour 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.
Maroochydore, Birtinya and Mooloolaba towers - 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.
Hastings Street, Ocean Street and Caloundra retail - A cafe, bar or surf shop fits a 10 kW system at $8,000–$12,000; Nambour's older main-street shops are where a switchboard upgrade at $1,500–$5,000 joins the quote, and the beachfront calls for marine-grade clamps.
Glass House Mountains and Mary Valley growers - Packing sheds, nurseries 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 the storm season.
What a Compliant Commercial Solar Quote Includes — Cost in Sunshine Coast
Before comparing Sunshine Coast 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

Commercial solar cost on the Sunshine Coast: Kunda Park sheds, Maroochydore towers and hinterland farms
A Sunshine Coast 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 distributors 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 and the salt air then write the rest of a Sunshine Coast quote. New sheds at Kunda Park and Caloundra West have clean metal decks and modern three-phase boards, so the quote stays close to the system price. Towers in Maroochydore CBD and along the Mooloolaba and Noosa beachfront 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, with marine-grade fixings specified. Nambour's older shops and the Yandina sheds 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 Sunshine Coast 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 Sunshine Coast
Quick answerSunshine Coast pricing steps by kilowatts: a Hastings Street cafe or Caloundra shop sits in the $8,000–$12,000 10 kW bracket, a Coolum workshop or Woombye packing shed at 20 kW to 30 kW pays $15,000–$26,000 to $22,000–$33,000, and a Kunda Park or Caloundra West shed at 50 kW to 100 kW pays $35,000–$55,000 to $70,000–$110,000.
A bigger Sunshine Coast array buys a lower per-watt price, $0.70–$1.20 across the range with the 100 kW Kunda Park 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 salt are the other levers on a Sunshine Coast job of any size. Beachfront towers need crane or cherry picker hire at $1,000–$3,000 a day plus dock and lift slots, and every coastal site from Caloundra to Noosa needs fixings rated for salt air. 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, booked more often on the sand.
Frequently Asked Questions — Commercial Solar Cost in Sunshine Coast
What is the price of commercial solar in Sunshine Coast?
From our Sunshine Coast 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 Sunshine Coast?
A 30 kW commercial solar system in Sunshine Coast costs $22,000–$33,000 installed after STCs, with $27,000 typical. A Maroochydore tenancy on a tower roof adds a structural engineering report at $800–$2,000 and crane or cherry picker hire at $1,000–$3,000 a day; a Glass House Mountains packing shed on a metal roof usually needs neither.
What does a 100 kW commercial solar system cost in Sunshine Coast?
Going by our Sunshine Coast table, expect $70,000–$110,000 for a 100 kW commercial system installed after STCs; the typical price is $88,000. Kunda Park, Warana and Caloundra West sheds are the usual Sunshine Coast 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 Sunshine Coast?
$0.70–$1.20 per watt installed after STCs on our Sunshine Coast 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 Sunshine Coast 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 Nambour's older main-street shops and the Yandina sheds. 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 Sunshine Coast need a structural engineering report?
A structural engineering report costs $800–$2,000 on our Sunshine Coast table, typically $1,200. Owners of Maroochydore, Birtinya and Mooloolaba towers usually ask for one before tilt frames go onto a concrete roof; a single-storey metal unit at Warana rarely needs it.
What does commercial solar panel cleaning cost in Sunshine Coast?
Commercial panel cleaning in Sunshine Coast costs $5–$15 a panel, with $10 a panel typical. Beachfront sites from Caloundra to Noosa book it more often because of salt spray; have the quote price it per visit.
Do Sunshine Coast 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 Sunshine Coast quote and check the panel and inverter models against the listed products.
