Byron Bay 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 wide Ballina and Ewingsdale sheds at the low end.
The building then shapes a Byron Bay quote. Tilt frames on a Jonson Street or Lawson Street commercial 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-access booking in the peak season; a Colorbond roof on an Arts and Industry Estate unit takes the same panels with a hoist. Older boards in the Mullumbimby and Bangalow main-street shops 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, booked often this close to the surf. All prices include GST.

Worked Commercial Solar Cost Scenarios — Byron Bay
Three Byron Bay jobs priced from the rows above: a Ballina wholesaler, an Arts and Industry Estate brewery and a hinterland macadamia farm. Each line names its row; the quote you get prices your own roof, board and connection.
Ballina wholesaler. A food distributor in the Southern Cross estate at Ballina 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.
Arts and Industry Estate brewery. A brewery in the Byron Arts and Industry Estate installs 30 kW on the taproom and production shed at $22,000–$33,000. The mezzanine roof section gets a structural engineering report at $800–$2,000 first, and the original switchboard is upgraded at $1,500–$5,000 to take the inverter and the brewhouse load.
Hinterland macadamia farm upkeep. A grower near Alstonville runs a 20 kW array installed at $15,000–$26,000 over the dehusking shed and books commercial panel cleaning at $5–$15 a panel after harvest, when dust from the orchard floor and salt haze have settled on the glass.

Commercial Solar Costs by Sector in Byron Bay
Byron Bay commercial solar runs from the Arts and Industry Estate at Ewingsdale and the Southern Cross estate at Ballina, through the Mullumbimby and Brunswick Heads workshops, to Jonson Street and Lawson Street hospitality, Bangalow and Lennox Head retail, Suffolk Park and Wategos accommodation, and the macadamia, coffee and dairy farms of the hinterland around Alstonville, Federal and Newrybar.
Ballina and Ewingsdale sheds - Distribution and production roofs take 50 kW to 100 kW arrays at $35,000–$55,000 to $70,000–$110,000, the sizes at which the installed cost per watt sits nearest the $0.70 floor of $0.70–$1.20.
Mullumbimby and Brunswick Heads 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.
Jonson Street and Lawson Street hospitality - Tilt frames on the two- and three-storey commercial buildings 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.
Bangalow, Lennox Head and Brunswick retail - A cafe, bar or surf shop fits a 10 kW system at $8,000–$12,000; the heritage main-street shops of Bangalow and Mullumbimby are where a switchboard upgrade at $1,500–$5,000 joins the quote, and the coast calls for marine-grade clamps.
Alstonville and hinterland growers - Dehusking sheds, dairies 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 harvest.
What a Compliant Commercial Solar Quote Includes — Cost in Byron Bay
Before comparing Byron Bay 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 Byron Bay: estate sheds, Jonson Street roofs and hinterland farms
For a Byron Bay small business the entry 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. Distributors and producers 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 and the salt air write the rest of a Byron Bay quote. New sheds at Ballina's Southern Cross estate and the newer Ewingsdale units have clean metal decks and modern three-phase boards, so the quote stays close to the system price. Jonson Street and Lawson Street buildings put panels on tilt frames over older roofs, bringing a structural engineering report at $800–$2,000, crane or cherry picker hire at $1,000–$3,000 a day and a street-access booking outside the holiday peaks, with marine-grade fixings specified. The heritage shopfronts of Bangalow and Mullumbimby 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 Byron Bay 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 Byron Bay
Quick answerByron Bay pricing steps by kilowatts: a Jonson Street cafe or Lennox Head surf shop sits in the $8,000–$12,000 10 kW bracket, an Arts and Industry Estate brewery or Alstonville dehusking shed at 20 kW to 30 kW pays $15,000–$26,000 to $22,000–$33,000, and a Ballina or Ewingsdale shed at 50 kW to 100 kW pays $35,000–$55,000 to $70,000–$110,000.
A bigger Byron Bay array buys a lower per-watt price, $0.70–$1.20 across the range with the 100 kW Ballina 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 Byron Bay job of any size. Town-centre buildings need crane or cherry picker hire at $1,000–$3,000 a day plus a street-access booking outside the holiday peaks, and every coastal site from Brunswick Heads to Lennox Head 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 this close to the surf.
Frequently Asked Questions — Commercial Solar Cost in Byron Bay
What is the price of commercial solar in Byron Bay?
From our Byron Bay 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 Byron Bay?
A 30 kW commercial solar system in Byron Bay costs $22,000–$33,000 installed after STCs, with $27,000 typical. A Jonson Street tenancy on a commercial roof adds a structural engineering report at $800–$2,000 and crane or cherry picker hire at $1,000–$3,000 a day; an Alstonville dehusking shed on a metal roof usually needs neither.
What does a 100 kW commercial solar system cost in Byron Bay?
Going by our Byron Bay table, expect $70,000–$110,000 for a 100 kW commercial system installed after STCs; the typical price is $88,000. Ballina's Southern Cross estate and the Ewingsdale sheds are the usual Byron Bay 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 Byron Bay?
$0.70–$1.20 per watt installed after STCs on our Byron Bay 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 Byron Bay 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 heritage main-street shops of Bangalow and Mullumbimby. 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 Byron Bay need a structural engineering report?
A structural engineering report costs $800–$2,000 on our Byron Bay table, typically $1,200. Owners of the two- and three-storey Jonson Street and Lawson Street buildings usually ask for one before tilt frames go onto an older roof; a single-storey metal unit in the Arts and Industry Estate rarely needs it.
What does commercial solar panel cleaning cost in Byron Bay?
Commercial panel cleaning in Byron Bay costs $5–$15 a panel, with $10 a panel typical. Coastal sites from Brunswick Heads to Lennox Head, and hinterland growers after harvest, book it more often; have the quote price it per visit.
Do Byron Bay 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 Byron Bay quote and check the panel and inverter models against the listed products.
