Solar installation Perth

The price depends on the size and quality of the system, but every eligible Perth install is helped by the federal small scale technology certificate rebate. It comes straight off your quoted price rather than being claimed back later, and on a common 6.6 kW system it is usually worth a couple of thousand dollars. Worth knowing is that this rebate steps down a little each year as the scheme winds up by 2030, so the subsidy is slightly smaller the longer you leave it. Mouritz quotes a fixed price with the rebate already applied, so you see the real out of pocket cost from the start.

The largest savings come from using your own solar during the day instead of buying power from the grid. Any excess you send back is paid through Synergy's Distributed Energy Buyback Scheme, currently 10 cents per unit for electricity exported between 3pm and 9pm and 2 cents at other times. Because you earn less for exporting than you pay to buy, the smart approach is to run bigger loads like the pool pump, dishwasher, washing and air conditioning while the sun is up. Most Perth homes cover a solid share of their yearly electricity this way, and adding a battery lifts it further.

It comes down to how much electricity you use and when you use it. A bigger system produces more, but there is little value in paying for power you export cheaply rather than use yourself. As a rough guide a 6.6 kW system suits many Perth homes, while households with a pool, ducted air conditioning, an electric vehicle or a battery often benefit from going larger. The most reliable way to size it is to look at a recent Synergy bill alongside your available roof space. Mouritz reviews both before recommending a size, so you are not paying for output you will not use.

Most Perth roofs suit solar well, and the direction of the panels does make a difference. North facing panels produce the most across a full day. West facing panels generate more in the late afternoon, which lines up with both the higher buyback rate and typical evening use. East facing panels help in the mornings. The main thing to manage is shading from trees, aerials or a neighbouring wall, although panel level electronics can reduce its effect. Mouritz checks your roof orientation, pitch and any shading as part of preparing your quote.

A battery stores your daytime solar so you can use it at night rather than buying from the grid, which makes good sense given Perth's low daytime buyback rate. Batteries are far more affordable now thanks to two rebates that can be combined. The federal Cheaper Home Batteries program takes roughly 30 percent off the cost of a typical battery, and the WA Residential Battery Scheme adds a state rebate on top, around $1,300 for Synergy customers. Joining a virtual power plant is generally required to receive the state rebate. Whether a battery pays for itself depends on your usage and budget, and Mouritz can model it for your home before you decide.

A standard home system is usually installed in a single day by Mouritz's licensed electricians and accredited installers, with larger or battery jobs sometimes taking a little longer. We handle the paperwork first, including the connection application with Western Power and Synergy. Good quality panels generally carry a product warranty of 12 to 15 years and a performance warranty of about 25 years, while inverters are commonly warranted for 5 to 10 years. Mouritz backs the whole job with local aftercare, so if anything ever needs attention you are dealing with a Perth team rather than an interstate call centre.
