Building a new home is an exciting milestone. You get to choose the perfect floor plan, the ideal kitchen layout, and the exact tiles for your bathroom. But while you’re picking out paint swatches, there is one crucial decision that will dictate your living costs for the next few decades: your home’s energy strategy.
Perth is one of the sunniest cities on the planet, making solar energy a no-brainer. However, with the introduction of new building energy ratings and the massive evolution of the WA grid, simply throwing a few panels on the roof after you move in is no longer the smartest approach.
Integrating a complete solar and battery storage system directly into your new build design is the ultimate way to lock in low living expenses from day one. Here is why you should plan your energy independence with Solar 2020
The New Build Advantage: Why Timing is Everything
Many homeowners think of solar as an “aftermarket” addition. But treating solar and battery storage as a core utility—like plumbing or standard electricity—during the construction phase unlocks massive structural and financial advantages.
1. Seamless Aesthetics and Clever Engineering
When you install solar during a new build, you can work with your builder and the design team at Solar 2020 to ensure your roof layout is optimised for maximum sun exposure without compromising your home’s street appeal. We can plan panel placement out of sight, ensure seamless conduit routing inside the walls (no ugly external capping!), and allocate the perfect, cool, secure spot in your garage or utility area for your inverter and battery storage unit.
2. Pre-Wiring for 3-Phase Power
Modern all-electric homes—complete with ducted reverse-cycle air conditioning, induction cooktops, and Electric Vehicle (EV) chargers, draw a lot of power. Requesting 3-phase power during your initial electrical design gives you the infrastructure to install a larger, highly efficient solar system (above 6.6kW) and a robust battery. Pre-wiring during construction is significantly cheaper than retrofitting a finished home later.
3. Rolling the Cost into Your Mortgage
By including your solar and battery system in your building contract or financing it early, you can often roll the upfront cost right into your primary home loan. Because the monthly savings on your Synergy electricity bill will likely outpace the minor increase in your mortgage repayment, your system can practically pay for itself from the moment you turn the key.
The 2026 Rebate Goldmine: WA State & Federal Incentives
If you are building in Perth right now, you are hitting the absolute sweet spot for government incentives. The upfront cost of battery storage has plummeted thanks to stacked state and federal programs.
| Incentive Scheme | What It Means for Perth New Builds | Max Potential Value |
| WA Residential Battery Scheme | A state government rebate for Synergy customers who install a Virtual Power Plant (VPP) capable battery. | Up to $1,300 |
| Federal Cheaper Home Batteries Program | An expansion of the Small-scale Renewable Energy Scheme (SRES) that provides an upfront discount via STCs based on battery capacity. | Up to $3,700 (for a standard 10kWh system) |
| Combined Rebate Power | Both incentives stack together seamlessly, drastically reducing the net cost of your battery. | Close to $5,000 in total savings |
| Plenti No-Interest Loans | Eligible WA households can access 0% interest loans to help finance the remaining balance of the system. | Up to $10,000 (with up to 10-year terms) |
Note on VPP Participation: To claim the WA State rebate, your system must be capable of joining a Virtual Power Plant (like Synergy Battery Rewards). This allows the grid to briefly draw on your battery during peak events, and you get financially rewarded with extra credits on your bill. It’s a win-win for your wallet and the Perth grid.
Designing the Ultimate Solar & Battery System for Perth Conditions
Perth’s harsh summer heat means cheap, generic solar components simply won’t last. At Solar 2020, we don’t believe in one-size-fits-all packages. We custom-tailor systems using tier-one, tried-and-tested brands built to withstand WA conditions.
Premium Panels: We highly recommend industry leaders like Jinko, REC, and Trina Solar. These panels maintain incredible efficiency even when the Perth thermometer ticks past 40°C.
Smart Inverters: Using top-tier smart inverters allows your solar panels and battery to communicate flawlessly, ensuring that every watt of energy generated is either used in the home, stored for the evening, or exported when tariffs are highest.
Future-Ready Sizing: With EV charging becoming standard, we help you map out your future energy footprint. Even if you don’t buy an EV today, we will ensure your system is completely ready for one tomorrow.
