Solar for New Build Homes
Solar & Battery Systems for New Build Homes
Building a new home gives you a unique, once-in-a-lifetime opportunity to design an energy system that is perfectly integrated into the architecture of your house. Retrofitting solar after construction often means visible exterior wiring, limited conduit routes, and missed structural optimisations.
By partnering with Sunergy Solar & Batteries during your pre-construction phase, you unlock four major advantages:
100% Concealed Cabling: Pre-wiring wall cavities before plastering ensures all electrical cabling, solar conduits, and battery connections remain invisible inside your walls.
3-Phase Power Maximums: New builds allow you to easily specify a 3-phase electrical supply, enabling larger solar array sizes (up to 15kW–30kW) and significantly higher grid export allowances.
Lower Construction Costs: Installing solar mounting systems while scaffolding is already in place dramatically reduces labor, safety, and equipment hire costs compared to retrofitting.
Pre-Build Integration vs. Post-Build Retrofitting
| Feature / Benefit | Pre-Build Integration (Sunergy) | Post-Build Retrofit |
| Conduit & Wiring Aesthetics | Completely hidden inside wall cavities | Surface-mounted exterior conduits |
| Electrical Supply Optimisation | Easy 3-phase wiring for faster EV charging & larger solar | Costly main switchboard upgrades often required |
| Inverter & Battery Location | Custom alcove/garage space planned into blueprints | Placed wherever space allows post-construction |
| Builder Coordination | Direct liaison between Sunergy and your site supervisor | Homeowner must coordinate trades after handover |
| Cost Savings | Combined scaffolding & reduced installation labor | Higher labor costs and retrofitting fees |
Technical Considerations for New Home Solar
1. 3-Phase Electrical Supply
If your site permits, always request a 3-phase connection from your builder. While single-phase homes are often capped at 5kW to 6.6kW solar inverters, a 3-phase system allows you to install 10kW, 15kW, or larger solar arrays with full battery integration and 22kW EV fast-charging support.
2. Strategic Battery & Inverter Placement
Modern home batteries (such as Tesla Powerwall or hybrid modular storage systems) require optimal environmental conditions to maximise battery lifespan. We work with your architect to allocate a sheltered, well-ventilated location—such as a dedicated garage nook—pre-wired with heavy-duty power conduits.
3. Smart Roof Pitch & Orientation
During the roof design stage, positioning major roof faces toward North or East/West split configurations ensures maximum solar generation throughout the day. We advise your builder on roof pitch and tile/tin fixing systems prior to roof installation.
4. EV Charger Pre-Wiring
Even if you don’t own an electric vehicle today, pre-wiring an EV cable from your main switchboard to your garage during framing costs a fraction of what it would cost to install down the road.
Why Choose Sunergy Solar & Batteries?
Unlike brokers who subcontract installations to third parties, Sunergy Solar & Batteries uses in-house, accredited local installers. This ensures strict quality control, full accountability, and seamless communication with your home builder.
Direct Builder Collaboration: We speak builder language. We coordinate directly with your site supervisor to stay on schedule with construction stages.
Tier-1 Quality Components: We only install proven, high-efficiency solar hardware with direct Australian manufacturer warranty backing.
Local Expertise: Based locally, we understand exact grid network requirements, local weather dynamics, and regional compliance rules.
Frequently Asked Questions
Should I install solar panels during construction or wait until after handover?
Installing solar during construction is highly recommended. Pre-wiring during construction allows electrical cables to be concealed within wall cavities, utilizes existing site scaffolding to lower labor costs, and ensures your system is active on move-in day.
Can I bundle solar and battery storage into my main home build mortgage?
Yes. When you contract solar and battery installation through your new build process, the cost can often be included in the total build contract, rolling your renewable energy investment directly into your standard home mortgage rate.
Do I need to tell my home builder before signing the contract?
Yes. Informing your builder early allows them to include a “solar pre-wire provision” in the construction schedule and gives Sunergy Solar & Batteries time to submit structural roof and grid connection plans before construction starts.
