A quick self-check before you enquire
- You're likely a good fit if
- Victorian business, commercial property owner, or tenant with landlord consent
- You hold a business ABN
- Your property has a suitable roof or structure
- You spend roughly $1,200+ per month on electricity
- There's no export limit on your connection (confirmed at assessment)
- Any industry — warehouses, offices, retail, hospitality, gyms, factories, schools, farms
- May attract additional cost
- Switchboard upgrades, if your existing board is non-compliant or under capacity
- Meter panel replacement beyond what's included
- Additional cabling beyond the standard allowance
- Roof structural repairs or reinforcement
- Trenching or underground conduit
- Crane hire, if a scissor lift is insufficient (rare)
Most sites see full payback in 4–5 years — then it's 15-plus years of dramatically lower power bills.
