Mount Colah backs right onto Berowra Valley National Park, so a lot of the blocks near the station slope hard and sit on sandstone — which changes how we run cable, mount panels and place a battery. We know that terrain well from jobs near Mount Colah, and we size every system around the roof and the block, not a one-size-fits-all layout.
Infinite quotes every Mount Colah job on site — whether that's a battery for backup power on a bushland block, a switchboard upgrade on a sloping property, or a full solar system on the roof. It's part of why Infinite holds a 5-star Google rating and won the Northern Beaches 2026 Outstanding Service Business Award, and why electrical and solar enquiries from Mount Colah and the surrounding North Shore keep coming back to the same crew.

Winner, 2026 Northern Beaches Local Business Awards
We're based on the Northern Beaches, but we service the North Shore regularly, and Mount Colah is one of the suburbs we're in most often.
Yes. Being near Berowra Valley National Park, a lot of Mount Colah homes are exposed to outages during storms or bushfire-related power shutoffs. We can wire key circuits — lighting, fridge, internet — through a backup panel so a battery keeps those essentials running even when the rest of the house is down.
It can affect access and cable runs more than the upgrade itself. We assess the slope and terrain on site as part of every quote, and plan the switchboard and any solar or battery cabling around it before we start.
We also service Berowra, Hornsby and Normanhurst — all a short drive from Mount Colah.
