Frequently asked questions
About commercial solar.
There is no honest per kilowatt figure. The price depends on the roof, the switchboard and cable run, whether Ergon needs export limiting, and the mounting your roof sheet needs. Send 12 months of interval data and we send a written quote within 24 hours.
Yes. Under Ergon's standard rules a three phase site can connect an inverter of just under 30 kVA. Above that, Ergon needs a negotiated connection, which takes longer and costs more. We lodge the application for you.
The roof work does not need the power off. The connection at the switchboard does, and we agree that time with you before the job starts.
Systems up to 100 kW get STCs, a discount that comes off the price up front. Larger systems earn LGCs over time as they generate. We tell you which one your system qualifies for.
Brad, our head technician, checks the roof before we finalise the quote. If the roof needs work first, we tell you.
The one sized against your interval data, not the biggest one that fits on the roof. A system earns its money by covering power you already use during the day, so when you use power matters more than how big the roof is.
There is no Mackay-only rebate. The STC scheme is federal, and its value comes off your quoted price up front, not as something you claim back later.
Yes. Ask us and we put you in touch with a finance provider.
