Solar for Brisbane Schools
Cut your school's $40k–$220k power bill by 60–80% with a 100–300kW rooftop system. 4–6 year payback on capital purchase, or zero-upfront PPA from 6.5c/kWh — plus LGC revenue, STEM curriculum dashboard and DoE-approved delivery.
★ 4.9 / 29 school installs · Capital + PPA + P&C funding modelled · Holiday-window install scheduling
Where school power bills actually go
Since Cooler Cleaner Schools, A/C is now the dominant load on every Brisbane campus — and it runs in perfect alignment with rooftop solar generation.
Air-conditioned classrooms (Cooler Cleaner Schools)
Since the Queensland Cooler Cleaner Schools rollout, almost every Brisbane state-school classroom, library and admin block runs ducted or split-system A/C through Term 1 and Term 4. A 30-classroom primary easily draws 80–140 kW of cooling between 9am and 3pm — your single largest load, and a perfect daylight match for solar.
1:1 devices, smartboards, server rooms
Modern schools run 600–1,500 active devices on chargers daily, interactive panels in every room, AV equipment, and a 24/7 server rack. Combined, IT and AV add 8–20 kW of continuous daytime load and ~3 kW overnight (server room A/C runs 24/7).
Tuckshop, hall, OSHC, pool
Commercial tuckshop fridges, freezers, ovens and bain-maries (daytime). Hall lighting/HVAC for assemblies. Outside School Hours Care 6:30am–6pm. Heated pool pumps and chlorination on swimming-program campuses. All daytime — all solar-friendly.
Hot water, lighting, pumps, sports lights
Heat pump hot water for change rooms, kitchen and cleaners' stations. LED lighting across blocks. Garden, sports-field and bore pumps. Evening sports-field lighting (best paired with battery, or run-as-export-credit during the day).
Why Brisbane schools are accelerating solar projects in 2026
Four reasons principals, business managers and P&C presidents are bringing solar projects forward — beyond simple energy savings.
60–80% power bill reduction
A typical Brisbane 600-student primary drops from $95k/yr to $20–32k/yr on a well-sized 120–180kW system. Secondary schools (800–1,800 students) commonly save $90k–$160k/yr. The savings free up funds for teaching resources, capital works or P&C-funded enrichment.
Multiple funding pathways
Three options: (1) capital purchase from school/P&C reserves — fastest payback, school keeps 100% of savings; (2) Solar PPA / Power Purchase Agreement — zero upfront, provider funds and you buy generated electricity at 6–9c/kWh vs 28–34c grid; (3) P&C fundraising hybrid — community ownership with brand-new fundraising narrative. We model all three for every school.
100kW+ unlocks LGCs
Systems over 100kW are ineligible for STCs but instead generate Large-scale Generation Certificates (LGCs) — annually for the lifetime of the system. Properly sold via an agent or aggregator, LGCs add $1,500–$4,500/yr revenue per 100kW installed for a typical school in 2026, on top of bill savings.
Curriculum & STEM asset
A live generation dashboard becomes a Years 3–10 teaching resource across Science (energy transformations), Maths (data interpretation), Geography (climate), Design & Technology (engineering) and HASS (sustainability). Many Brisbane schools (BSDE, Anglican, independent) now feature solar in open-day marketing and Annual Reports.
Real example: 620-student Brisbane state primary
Real 620-student Brisbane state primary — 150kW rooftop across 4 blocks, holiday-window install, LGC-registered with aggregator.

Don't sign a 15-year PPA without modelling the capital alternative
PPAs are a legitimate, valuable funding mechanism — but some PPA-only providers cold-call schools with a "no capital required" pitch that hides $400k–$900k of present-value savings going to the PPA owner instead of the school over 15 years. Always model capital purchase, P&C-funded hybrid, and PPA side-by-side before signing. We provide all three at no cost.
