Solar for Queensland Farms & Agriculture
Cut your farm's $25k–$280k power bill by 60–80% with a 30–200kW solar (+ optional battery). 3.5–5 year payback after STCs, IAWO and diesel-pump replacement — plus tariff optimisation, cold-chain backup and a future-ready electric-ag fleet.

Where farm power bills actually go
Irrigation and dairy/packing are the dominant loads on most QLD farms — and they run almost exclusively during daylight hours. That makes farms one of the highest-ROI solar applications in the country.
Irrigation pumps (centre pivots, drip, flood)
Centre pivot pumps (15–75 kW per pivot), drip irrigation booster pumps, bore pumps, flood-irrigation lift pumps. Pump scheduling is the easiest energy win on a farm — run between 10am and 3pm on solar and you essentially eliminate pumping cost. Variable-speed drives (VSDs) on existing pumps amplify the saving.
Dairy shed, packing shed, processing
Vacuum pumps, milk chillers, hot water for dairy wash-down (huge load — 6,000–18,000L hot water per day on a 300-cow farm). Packing line conveyors, graders, washers and pre-coolers on horticulture. All daytime operations — solar covers the lot.
Cold rooms, freezers, controlled-atmosphere storage
Post-harvest cold rooms (10–80 kW continuous depending on volume), blast freezers, controlled-atmosphere apple/avocado storage. Mostly continuous load — solar covers the daytime portion, battery handles overnight. Cold-chain protection is also a strong case for battery backup during storm-season outages.
Sheds, workshops, EV ag equipment
Workshop lighting, welders, compressors, hydraulic test rigs. Increasing fleet of battery-electric ATVs, small tractors, mowers and forklifts — perfectly matched to solar charging. Future-proofing for diesel-to-electric transition (still 5–10 years out for large tractors, but immediate for utility vehicles).
Why QLD farmers are installing solar in 2026
Four reasons primary producers across Queensland are accelerating solar projects — beyond simple bill savings.
60–80% farm power bill cut
A typical QLD horticulture or dairy farm drops from $92k/yr to $20–32k/yr on a well-sized 100kW system. Large operations (broadacre irrigators, intensive horticulture) commonly save $150k–$400k/yr on 200–500 kW installs. For irrigation-dominated farms, savings on diesel-pump replacement add another $40k–$120k/yr.
Instant Asset Write-Off + accelerated depreciation
Primary producers can deduct 100% of solar install cost in the year of purchase under the Instant Asset Write-Off (for businesses under $50M turnover in 2026), or use accelerated depreciation under primary producer rules. Combined with STCs (deducted at purchase up to 100kW) and LGCs (annual revenue stream over 100kW), the after-tax payback drops to 3–4 years on most farms.
Solar diesel-pump replacement
Off-grid irrigation pumps running on diesel cost $0.55–$0.85 per kWh-equivalent. Replacing with a solar+battery direct-drive pump or solar+grid hybrid drops marginal cost to near zero. Diesel-pump replacement typically pays back in 2.5–3.5 years on its own. We design the conversion with your existing irrigation engineer.
Farm Management Deposit (FMD) integration
Solar capex is a planned, predictable expense that pairs neatly with FMD withdrawals — a tax-efficient way to deploy stored income against a long-life productive asset. Your accountant can model the timing, but the combination of FMD withdrawal + IAWO + STCs/LGCs is often the lowest-effective-cost path to solar for established family farms.

Don't pay for solar capacity you can't actually use without scheduling
The single most common rural solar mistake is oversizing the panel array without changing how pumps and cold rooms are scheduled. A 200kW system on a farm still running pumps at 3am exports 60–70% of generation at 4c/kWh — appalling ROI. Insist that your installer quotes pump scheduling automation as a non-negotiable line item, and that the proposal shows projected self-consumption ratio (target 65%+ for farms without battery, 85%+ with battery).
