Solar PV and battery storage is a specialty within electrical work. Installer accreditation through Solar Accreditation Australia sits on top of a standard electrical licence, and system design involves PV-specific expertise most general electricians don't hold. Rather than spread ourselves thin, Millar Electrics focuses on core electrical work and refers solar and battery enquiries to installers we've worked alongside across the eastern suburbs. To do solar well you need installer accreditation from Solar Accreditation Australia, current product knowledge on panels and inverters that change every year, and the bench depth to support a system for its 25-year panel warranty. One-person general electrical businesses that "also do solar" rarely deliver on all three. We'd rather tell you that than take your money and hand the job off to someone cheaper.
What we can do: help you evaluate quotes you've received, sanity-check whether your existing switchboard can accept a PV inverter, and handle the follow-on electrical work most solar projects trigger. That means adding a dedicated circuit for a heat pump, running power to a new battery cabinet, or wiring an EV charger to draw from your own generation. Ask us for a referral and we'll point you at someone we'd use on our own house.
Standards the work has to meet
Solar PV installations are governed by AS/NZS 5033 (PV array installation), grid-connect inverters by AS/NZS 4777.1 and AS/NZS 4777.2, and battery storage by AS/NZS 5139 (safety of battery systems). When we review a quote, that's what we check it against, alongside Clean Energy Council accreditation for the installer and approved-product listing for the panel and inverter models. The interface with the rest of your installation (consumer mains cabling, switchboard, isolation, surge protection) is AS/NZS 3000. That's our side of the boundary.
