What Our Solar Upgrades Cover

1

System Performance Assessment

We start by reviewing your current array, checking panel output, wiring condition, and how your system copes with Perth's intense UV and heat. This assessment identifies underperforming components and shows where added capacity or replacement parts will deliver the biggest improvement to your daily generation.
2

Adding Panels and Capacity

Where your roof allows, we add extra panels to increase generation and match rising household demand. Trained technicians confirm your existing components can support the expansion, then integrate new panels with compatible mounting and wiring so the whole system works as one efficient unit.
3

Component and Wiring Updates

Older systems often have ageing cabling, connectors, or isolators that limit output or pose safety concerns. We update worn components, tidy the wiring, and bring the installation in line with current standards, ensuring long-lasting results and reliable performance across the array.

Related Upgrade Options We Offer

Adding Extra Panels

If you plan to add storage later, we can prepare your upgraded system so it’s ready for a battery when you are. This suits households wanting to keep options open without committing straight away. The result is a setup that adapts easily as your energy goals grow.

Battery Retrofit

We can add or upgrade monitoring so you can track generation and consumption in real time from your phone. This suits owners who want clear visibility over how their upgraded system performs. You’ll spot issues early and make better decisions about when to run high-use appliances.

Meter & Switchboard Upgrades

Faded, damaged, or shaded panels drag down your whole array’s output. We replace failing modules and, where practical, reposition panels for better sun exposure. This suits older systems that have lost efficiency, restoring generation closer to what the setup should be producing.

System Rewiring & Compliance

Standards change over time, and older installations may no longer meet them. We inspect your system against current requirements and address any gaps found. This suits homeowners preparing to sell or simply wanting confidence their solar is safe, compliant, and running as it should.

How the Upgrade Process Works

On-Site Assessment

We visit your property to inspect the existing array, roof space, and switchboard. This lets us understand what you have, what condition it’s in, and what upgrade options genuinely make sense for your home and energy use.

Upgrade Plan and Estimate

Based on the assessment, we outline recommended improvements, the components involved, and what to expect from the finished result. You get a clear plan and estimate before any work begins, so there are no surprises.

Installation and Integration

Our technicians carry out the upgrade with specialist equipment and attention to detail, whether that’s adding panels, updating wiring, or replacing components. We integrate the new elements with your existing setup so everything runs as a single, reliable system.

Testing and Handover

Once work is complete, we test the full system to confirm it generates and reports correctly. We walk you through the changes, show you how to check performance, and share simple aftercare tips to keep your system running well.

Why Upgrade Your Existing Solar

More Generation From Your Roof

Adding capacity or replacing tired panels lifts your daily output, helping cover more of your household demand from the sun. For growing families or homes with rising energy use, an upgrade often makes far better sense than living with a system that no longer keeps up.

Better Value From Existing Gear

Rather than starting over, upgrading builds on what already works. Where your existing mounting, wiring, or inverter is still sound, we retain it and add only what's needed. This keeps the upgrade worth the investment while extending the useful life of your original installation.

Safer, Standards-Compliant System

Perth's UV and heat take a toll on older installations, and wiring can degrade over time. Updating worn components and bringing the system to current standards reduces fault risk and gives you a safer, more dependable setup that's easier to maintain for years ahead.
