For most businesses with meaningful daytime power use, yes. Perth’s strong sunlight means a well-sized solar system can offset a large share of your electricity costs, though the return depends heavily on how much power you use during daylight hours versus at night, and on your tariff. A site with steady weekday operations usually sees a better result than one that runs mostly after dark.
Cost depends on system size, panel and inverter choice, roof type and access, switchboard and three-phase work, and whether battery storage is included. Grid connection requirements and any structural upgrades also play a part. Because every site differs, we assess yours in person and provide a written quote rather than a generic figure, so you can compare proposals on the same terms.
The on-roof installation of a typical commercial system takes from a few days to a couple of weeks depending on size. The longer part is usually before and after: site assessment, design, and Western Power connection approvals, which can add weeks. We give you a realistic timeline once we’ve assessed the site, and keep approvals moving in the background.
Most commercial sites already have three-phase supply, which commercial-scale solar inverters are designed to work with. It allows larger systems and balanced output across your switchboard. We check your supply and switchboard capacity during assessment; if an upgrade is needed, we flag it early so it’s factored into the plan and quote rather than becoming a surprise.
Yes. Many businesses start with a solar array and add battery storage or extra panels as their demand grows or budgets allow. Designing with future expansion in mind, such as leaving inverter and switchboard headroom, makes later upgrades simpler and cheaper. We can review an existing system and advise what it can realistically support before you commit.
Look for CEC-accredited installers who use quality equipment, model your usage properly rather than selling a stock size, and clearly explain their warranties and after-sales support. Ask how they handle grid connection and what happens if the system underperforms. Contact us and we’re happy to walk you through how we approach each of these.
