Faster installation times (without cutting corners)

Costline prides itself on providing faster than average installation times, without cutting corners. With one of the largest nationwide networks and offices right across Australia, we can have your system up and running in nearly half the time that most installers provide. Your residential or commercial property will begin generating clean electricity within an average of 4-6 weeks (based on approval), regardless of system size.

Unbeatable value

Given our huge supplier network and long-standing vendor relationships, we routinely receive volume discounts for the PV components we order. We’re able to pass these savings on to you. No solar installer in Australia can approach the level of service we provide – certainly not at the prices we charge!

Unrivaled customer support and technical expertise

Costline operates customer care across Australia with extended contact hours. Every Solar PV System that we provide comes with a 5 year workmanship warranty that protects you from any defects resulting from improper installation. This is more than twice the average cover that most PV contractors offer.

We only use quality, tier 1 systems from top-performing manufacturers and all of our Solar PV Systems come with a minimum 25-year panel performance warranty to ensure stable system performance and reliability.

We have access to the largest range of Solar PV panels and inverters in Australia and our experienced installers have already installed over 90,000 kilowatts of solar capacity PV components.
