Solar Panel Installation in Laverton

The post-war housing stock in Laverton is one of the most common places we replace a switchboard outright rather than upgrade it. Not because of a preference for bigger jobs, but because a board that has been extended repeatedly across decades has no compliant way to take a new solar circuit.

Where a full replacement is needed the cost runs to the upper end of the $800 to $3,500 range and sometimes beyond it, particularly if the consumer mains also need attention. The benefit is that everything after it, solar, a battery, an EV charger, a heat pump, lands on a board that can actually take it.

Because of the industrial zoning, three-phase supply is far more available in Laverton than in a typical residential suburb. For solar that opens up two things: three-phase inverters, which spread generation evenly and reduce voltage rise at your connection point, and larger arrays that Powercor is more comfortable approving.

It also means a Laverton home is often better placed than its neighbours for the next step. Three-phase supply supports 22kW EV charging and higher-output battery inverters, so a household planning to electrify over the next few years has fewer bottlenecks to pay for later.

The industrial fringe along Aviation Road and toward the RAAF Williams boundary has large warehouse roofs, and the economics there are different from residential. Commercial buildings usually consume during daylight hours, which is exactly when the array generates, so self-consumption rates are high and payback is typically much shorter than on a home.

Commercial systems are still governed by the same standards and still need Powercor approval, but the design work is about structural loading, roof sheet condition and matching array size to a business load profile rather than a household one.

Residential Laverton roofs run from older tile to modern Colorbond on the newer estate lots. The older tile gives you decent northern faces on single-storey homes, with the usual caveats about tile age and brittleness. The newer estate roofs are simpler to install on and often smaller in usable area.

System sizes here typically land between 5kW and 8kW on residential, with more where a household has a genuine daytime load. On price, a quality 6.6kW system is $4,500 to $8,500 before incentives, roughly $3,000 to $6,000 after STCs, with up to $1,400 more for eligible households under Solar Homes and its $150,000 combined income cap from 1 July 2026.
