Commercial energy is the single biggest cost lever you can pull.
Victorian businesses are facing the highest commercial electricity tariffs in a decade. The good news: rooftop solar is also the cheapest it's ever been, federal STC rebates remain generous, and battery storage is now genuinely commercially viable for sites with peak demand charges.
Sunline's commercial team designs every system around your real-world load — not a generic kW number. The result is a faster payback, a longer asset life and a system you actually use, not one that exports half its generation.
Built for Victorian businesses, large and small.
Whatever the sector, the principles are the same: honest design, premium products, project-managed delivery.
