Honest energy advice — built on more than a decade of Victorian installs.
Sunline Energy started with a frustration that's now an industry cliché: too many solar companies overpromise, undercommit and disappear after install.
We've spent the last 11+ years doing the opposite. Quoting honestly. Recommending the right system — not the most expensive one. Picking up the phone in year two, year five, year nine. That approach has powered 10,000+ installations across Victoria and earned us 300+ Google reviews at 4.7★.
Today we're a full-service energy retailer designing and installing solar, batteries, heat pump hot water, EV chargers and commercial systems for homes and businesses across Victoria. As a NETCC Approved Seller we're held to the New Energy Tech Consumer Code — the highest consumer protection standard in our industry.
Every Sunline install is backed by our 10-year workmanship warranty in writing — not just the manufacturer's product warranty. That's our promise that we'll be the team you call if anything ever needs attention.
A decade of measurable impact.
Four principles that drive every install.
The same values our first customers got in 2014 — still how we work today.
Honest advice
We recommend the right-sized system for your home — not the biggest sale.
Quality first
Tier-1 panels, premium inverters and proven battery brands. Always.
Workmanship in writing
10-year workmanship guarantee, every job. Uncommon in our industry.
Long-term aftercare
Monitoring, warranty support and a real person at the end of the line.
