Most commercial-scale systems in Kewdale need Western Power approval before they connect and export. The size you can install, and any export limit, depends on the capacity at your part of the network, so the result shapes the design, not the other way round. We lodge the application, manage the back-and-forth, and set realistic timing. Approval can take weeks and occasionally comes back with a lower export cap, which we then design around.
The main drivers are roof size and sheet type, system capacity, any switchboard or metering upgrade, and whether your Kewdale unit is tenanted. Large warehouse spans can lower the cost per panel, while older or corroded roofing, tricky height access and a tight switchboard add to it. Certificates reduce the net figure. We assess the site, confirm what needs upgrading, and provide a written quote rather than a guess.
Often, yes. Many Kewdale industrial units have switchboards sized for the original fit-out, with little spare capacity for an inverter connection. We check the board, main switch rating and available ways during the site visit, and flag early if an upgrade or a new sub-board is needed. In a tenanted unit this also raises who authorises and pays for board work, which we confirm before quoting.
