Warehouse-scale system sizing
From a single tilt-slab unit up to multi-megawatt distribution campuses — here's how Brisbane warehouses map to system size, payback, and rebate eligibility.
30–100 kW (small unit)
Tilt-slab industrial unit, 600–1,500 m² roof. Suits light manufacturing, cold storage units, single-tenant logistics. Typical install $35k–$95k after STCs, $9k–$22k annual saving. Payback 3.5–4.5 years. STC-eligible, no LGC paperwork.
100–250 kW (mid warehouse)
Standard logistics/distribution warehouse, 1,500–4,000 m² roof. Suits transport, cold-chain, light manufacturing. Typical install $110k–$240k after STCs, $32k–$78k annual saving. Payback 3–4 years. Sits on the STC/LGC boundary at 100kW.
250–500 kW (large warehouse)
Multi-tenant or single large distribution centre, 4,000–8,000 m² roof. LGC-only (not STC) above 100kW capacity threshold. Typical install $260k–$510k, $80k–$170k annual saving. Payback 3–3.5 years. Often paired with monitoring + demand-shaving optimisation.
500 kW – 1 MW+ (industrial)
Major manufacturing, refrigerated DC, multi-roof campus. 8,000+ m² roof. Approval becomes 5.5MW NER (network) territory, with grid connection studies. We partner with EPCs above 500kW. Annual savings typically $170k–$380k. Payback 3–4 years on PPA or capex purchase.
Why warehouse solar makes hard financial sense in 2026
Beyond simple energy savings — four reasons warehouse owners are accelerating commercial solar projects this year.
Instant Asset Write-Off
Under the 2026 small/medium business write-off rules, businesses with aggregated turnover under $50M can immediately deduct the full cost of a commercial solar system in the year of install. On a $240k system that's $72k of tax saved at 30% corporate rate — material on top of STCs and energy savings.
STCs + LGCs
Systems under 100kW receive Small-scale Technology Certificates (STCs) deducted from the purchase price — typically 25–30% of system cost. Systems over 100kW receive Large-scale Generation Certificates (LGCs), claimed as an ongoing revenue stream for 10–15 years (typically $30–$60 per MWh generated).
Lock in energy prices
Commercial energy costs in QLD rose 28% in 2023–2025 with another 8–15% forecast through 2026. A 25-year solar warranty effectively locks in a stable energy cost for 80% of your daytime use — a major hedge against future retail and network price hikes.
ESG & Scope 2 reporting
Warehouses tendering for ASX200 logistics contracts, government supply chains or international FMCG clients are increasingly asked for Scope 2 emissions data. On-site solar typically reduces Scope 2 by 50–75% — material to tender scoring and Climate-Related Financial Disclosure (CRFD) reporting from 2026.
Real example: 4,200 m² Yatala distribution warehouse

Our 4-step commercial process
12–24 weeks from first call to commissioning — engineered, network-approved, and installed without disrupting your operations.
Free desktop feasibility
We pull 12 months of your interval data from your retailer, model self-consumption against Brisbane solar generation, and produce an indicative ROI within 48 hours.
Site & structural audit
Engineer site visit — roof load capacity, switchboard headroom, network connection point, shading analysis with drone survey. Detailed engineering report within 2 weeks.
Fixed-price proposal & finance
Detailed scope, fixed price, payback model with sensitivity analysis, finance options (chattel mortgage, PPA, capex). LGC modelling for systems over 100kW.
Network approval & install
Energex application (typically 4–8 weeks for sub-100kW, 8–16 weeks for 100–500kW). Install windows scheduled around your operations — typically out-of-hours for active warehouses.
Don't accept "$/W" quotes without a self-consumption model
Commercial solar ROI lives or dies on self-consumption %. A 300kW system on a weekday-only warehouse with 60% self-consumption pays back in 3 years. The same system on a weekend-heavy retail site might only hit 40% — and payback stretches to 6+ years. Always insist on a half-hourly self-consumption model using your real interval data, not a generic "$/W" benchmark.
