Commercial Solar in Brisbane
Brisbane businesses are increasingly turning to commercial solar to control electricity costs, generate LGC revenue, and improve sustainability credentials. With 5.2 peak sun hours per day and commercial electricity rates averaging 32c/kWh, the economics have never been more compelling for Brisbane businesses investing in 50 kW to 500 kW+ rooftop solar systems.
Local Insight
Brisbane and South East Queensland have among the best commercial solar conditions in Australia — 5.2 peak sun hours, high electricity rates, and a rapidly growing business corridor from Brisbane CBD through to Logan, Ipswich, and the Sunshine Coast. Manufacturing and logistics businesses in the Acacia Ridge, Eagle Farm, and Richlands precincts are particularly well-suited.

Frequently Asked Questions — Commercial Solar Brisbane
How much does commercial solar cost in Brisbane?
Brisbane commercial solar installations range from approximately $50,000 for a 50 kW system to $400,000+ for a 500 kW installation before incentives. Installed costs in South East Queensland typically run $900–$1,050 per kW at scale — among the most competitive in Australia due to the active local installer market.
Why is Brisbane particularly good for commercial solar?
Brisbane combines Australia's most favourable factors: 5.2 peak sun hours per day (among the highest of any major city), high commercial electricity rates (averaging 32c/kWh), rapidly growing industrial precincts, and a competitive installer market. These combine for payback periods as short as 3 years for well-positioned sites.
Which Brisbane business precincts get the best commercial solar ROI?
Acacia Ridge, Eagle Farm, Richlands, and Darra in Brisbane's south and southwest have large manufacturing and logistics operations ideally suited to 100–500 kW commercial systems. The expanding Logan and Ipswich industrial corridors are also increasingly popular for large-scale commercial solar.
Does Queensland have additional commercial solar incentives?
Queensland businesses access federal STCs (systems under 100 kW) or LGCs (100 kW+). The Queensland government also periodically runs business energy productivity programs. Your installer can advise on current state-level opportunities. The strong irradiance in QLD makes the federal incentives particularly valuable here.
What's the LGC revenue for a Brisbane commercial system?
A 200 kW Brisbane system generates approximately 320 MWh/year — earning around $13,000–$14,000 in LGC revenue at ~$42/MWh, plus approximately $48,000–$58,000 in annual electricity savings. Total annual benefit commonly exceeds $60,000 for 200 kW installations in Brisbane.
How does commercial solar compare for different business types in Brisbane?
Cold storage and food processing businesses in Brisbane's industrial areas see particularly strong ROI due to very high electricity consumption. Retail centres (Westfield-style) benefit from large roof areas and peak consumption aligning with peak solar. Schools and government buildings in SE QLD have seen some of the fastest paybacks in the country.
