When you’re renovating, you’re not just updating your home — you’re opening a rare window of opportunity. With walls open, roof work underway, and electricians and builders already onsite, it becomes the ideal moment to future-proof your home with solar, battery storage, and EV-charging readiness. The work you do now can dramatically improve your home’s efficiency, comfort, and long-term energy independence.
The alternative? Retrofitting these upgrades later — which often means higher costs, extra labour, visible conduit runs, patch repairs, and far more disruption. By planning smart during your renovation, you avoid double-handling and set yourself up for a home that’s ready for tomorrow’s energy landscape.
This guide is designed specifically for renovators, sitting alongside Regen Power’s new build and upgrade resources. Whether you’re extending, rewiring, reroofing, or modernising an older WA home, this renovation-focused roadmap will help you integrate clean energy solutions seamlessly — while your home is already open and ready for transformation.
Step 1 – Map Your Future Energy Lifestyle (Not Just Today’s Bills)
Before choosing solar, batteries or EV wiring during a renovation, the smartest move is to zoom out and think beyond today’s electricity usage. Renovations are rare opportunities — and the decisions you make now will shape your home’s energy needs for the next decade.
Start by imagining your household 5–10 years from now:
- Planning to buy an EV?
Even one electric vehicle can add 8–15 kWh per day to your energy demand. Preparing wiring and switchboard space now avoids expensive rework later. - Adding a pool, granny flat or studio?
Pools and additional living spaces significantly increase daytime loads, making larger solar arrays and battery storage more valuable. - Working from home more often?
Computers, monitors, cooling and heating all increase weekday energy use — making self-consumption and backup power more important.
If you already have solar, check your inverter monitoring app to see when and how you use power. If not, a quick Synergy bill check or a simple DIY home energy audit can reveal your baseline usage and peak times.
By understanding your evolving lifestyle early, you can design a solar and battery-ready home that maximises self-consumption, energy savings and long-term sustainability — without costly retrofits down the track.
Step 2 – Design the Roof & Shading with Solar in Mind
When you’re renovating — especially adding an extension, second storey, or new patio — the roof design you choose today will determine how powerful and productive your future solar system can be. This is the moment to plan intentionally, because once the build is complete, your options become limited and more expensive to change.
Start with the fundamentals: roof orientation and available space. In WA, north and north-west facing roof planes deliver the strongest year-round solar output. During renovations, aim to maximise clean, uninterrupted space on these faces so you can fit a high-performing solar array without compromises.
Just as important is planning for future shading. New pergolas, verandahs, higher rooflines, or even repositioned air-conditioning units can cast long shadows that reduce solar generation. Catching these issues during the design phase allows you to reposition structures before they become permanent blockers.
Roof material also matters. Whether you’re using Colorbond, tile, or newer architectural finishes, make sure the chosen material is compatible with standard solar mounting hardware to keep installation simple and affordable.
A quick checklist to share with your builder or architect:
- “Show the solar zones on the plan.”
- “Avoid placing vents, chimneys or skylights on the best solar roof face.”
- “Consider shading impacts of new structures before finalising the design.”
Thoughtful roof planning now ensures your renovated home is truly solar-ready — efficient, flexible and future-proof.
Step 3 – Get the Wiring Right While the Walls Are Open
If there’s one renovation upgrade that delivers massive future savings, it’s pre-wiring your home for solar, batteries, and EV charging while the walls are already open. Cabling is cheap compared to labour — and during a reno, the labour is already onsite. Doing this groundwork now can save you thousands later and prevents messy retrofits that involve cutting walls, running awkward conduit, or relocating switchboards.
Start with the essentials:
- Conduit from the roof to the inverter position.
This ensures a clean, efficient cable run for your future solar system, without needing external conduit down your wall. - Battery-ready wiring in the garage or side area.
Even if you’re not installing a battery yet, leaving space and suitable cabling (AC or hybrid-ready DC paths) makes a future install simple and affordable. - A dedicated circuit for an EV charger.
EV adoption is accelerating fast. Pre-running a suitable cable to the garage or carport sets you up for a seamless charger install later.
Your switchboard also deserves attention during a renovation.
Older boards often can’t accommodate solar, let alone batteries or modern safety requirements. Use this moment to:
- Upgrade to a compliant, modern switchboard with RCDs and room for additional breakers.
- Make space for smart meters, energy monitoring hardware, and potential backup circuits.
Getting the electrical backbone right during your renovation future-proofs your home, lowers upgrade costs dramatically, and ensures you’re ready for whatever clean-energy technology you choose to add next.
Step 4 – Choose Hardware That Keeps Your Options Open
When you’re renovating, every hardware decision should protect your future choices. This is where Regen’s product expertise becomes invaluable.
- Hybrid Inverters: Even if you’re not ready for a battery today, installing a hybrid inverter now saves thousands later by avoiding a full inverter replacement.
- High-Efficiency Panels: Premium N-Type or high-output modules help maximise generation on smaller or complex roofs — backed by long warranties for peace of mind.
- WA Grid Compliance: Ensure your system is fully compatible with WA’s Emergency Solar Management rules, which apply to new and upgraded systems across the state.
Regen Power works only with tier-1 panels, top-tier inverters and leading battery brands, ensuring long-term performance, warranty support and seamless future upgrades.
Step 5 – Stack the Rebates and Finance Smartly
Renovating is the perfect time to take advantage of multiple incentives:
- Federal STCs: Reduce the upfront cost of your solar PV system automatically.
- WA Residential Battery Scheme + Federal Cheaper Home Batteries: Support for homeowners planning to add storage — now or later.
- Finance options: Bundling solar/battery into your renovation loan or mortgage can smooth out cashflow and accelerate the payback period.
A smart financial strategy can turn your renovation into an energy upgrade without blowing the budget.
Step 6 – Real-Life Inspiration: WA Renovation Stories
Here are a few real-world scenarios you can later expand into case studies:
- 1970s Perth Reno: Owners rewired and planned for a future battery and EV charger. Two years later, they added both — no extra structural work needed.
- Coastal Modernisation: During roof re-sheeting, a family installed high-efficiency N-Type panels with a hybrid inverter, cutting bills and boosting resilience.
Each story proves the same point: thoughtful planning during renovations delivers lower bills, higher comfort, increased property value, and a stronger sustainability profile.
Conclusion: Don’t Let Your Renovation Miss the Energy Upgrade
Once the renovation is complete, your chance to create a solar-, battery-, and EV-ready home becomes far more expensive. Planning now ensures your home is efficient, future-proof and ready for the next decade of clean energy living.
