Got the Home Battery Rebate?
Your Existing Solar May Not Be Big Enough to Charge It.

Got the Federal Home Battery Rebate? Your existing 6.6 kW system likely can't fully charge it each day. The result: a half-charged battery every morning and Synergy bills you didn't expect.

A 10–15 kWh battery needs 10–13 kW of solar to charge reliably each day.
Most Perth systems pre-2021 were sized for grid export; not battery charging.
Adding panels to your existing system is the fastest and most affordable fix.
We check your inverter's headroom at no cost before recommending anything.

Signs your solar is too small for your battery

Battery rarely reaches 100% charge
Still getting Synergy bills despite having a battery
Battery nearly empty every morning
Battery not finishing charge until late afternoon
AC or EV charging leaves nothing for the battery
The fix isn't a new battery. Your battery is working fine. Your solar panels simply aren't generating enough to charge it. More panels fix this directly.

Why Your Existing System
No Longer Matches Your Lifestyle

Most Perth homeowners installed solar when it was affordable and sized for a simpler household. Since then, EVs, batteries, home offices, and growing families have changed the energy equation completely.

Battery Not Reaching Full Charge

Your panels aren't producing enough energy to power the home and charge the battery at the same time. Adding more panels solves this directly; no new battery required.

EV Charging From the Grid

Charging an EV at home can double your household electricity demand. Without extra panels, you're effectively charging your car on grid power; at grid prices, every day.

Electricity Bills Still Too High

Your solar is generating; but not enough to cover rising daytime loads. You're drawing from the grid more than you should, and every unit costs more than two years ago.

Ducted AC Overloading the System

Ducted AC running through a Perth summer draws 3–5 kW continuously. A 6.6 kW system from 2016 was never designed to carry that load while keeping everything else running.

More People Home, More Power Needed

Working from home, teenagers, home offices; a household that was two adults in 2018 may now be running five devices simultaneously, all day. Your system wasn't sized for this.

Pool, Spa & High-Draw Appliances

Pool pumps, underfloor heating, workshops. The modern Perth home runs far more continuous load than any entry-level solar system from 2016–2020 was designed to cover.

The Smarter Solution

Why Add Panels Instead of
Replacing Your Whole System?

Replacing an entire solar system is expensive, disruptive, and for most Perth homeowners, completely unnecessary. Adding panels to your existing inverter costs less, takes less time, and delivers a better return on investment.

Is This You?

Built for Perth Homeowners
Who Already Have Solar

If your situation matches any of these, a solar add-on package could reduce your electricity bills; typically within weeks of installation.

🔋

Battery Owners

Your battery isn't reaching full charge each day. More panels give it the energy it needs to perform at full capacity every day; especially after getting the Federal Rebate.

Recommended: 10 kW or 13.3 kW
🚗

EV Owners

Charging your EV from the grid is costing you more than it should. Extra solar panels mean your car charges from free solar energy instead of peak-rate grid power.

Recommended: 10 kW or 13.3 kW
👪

Growing Families

More people at home, more devices running all day. Your 6.6 kW system from 2018 simply wasn't sized for a household of four or five in 2025.

Recommended: 10 kW package
🏠

Home Renovators

Adding a room, home office, or workshop? Expand your solar generation now so your energy supply keeps pace with your upgraded home.

Recommended: 10 kW or 13.3 kW
💧

Pool & Spa Owners

Pool pumps, heating, and filtration run for hours every day. A solar add-on can cover most of this load with free energy from the sun.

Recommended: 6.6 kW or 10 kW
❄

AC-Heavy Homes

Perth summers hit hard. Ducted air conditioning is one of the biggest electricity draws in any home; extra panels mean more free cooling hours every day.

Recommended: 10 kW or 13.3 kW

Perth Electricity Prices Have Risen 30%+ Since 2021

Every day your system runs below capacity is money going to Synergy unnecessarily.

Common Questions

Questions About Adding Panels
to an Existing Solar System

Yes, in most cases. If your inverter has available input capacity (headroom), additional panels can be connected without replacing any existing equipment. We assess your inverter's headroom during a compatibility check before recommending any package. Most modern inverters including Fronius, Sungrow, SMA, GoodWe, and Huawei support add-ons.

This is almost always because your solar panels don't generate enough energy to power your home and charge the battery simultaneously. A modern 10–15 kWh battery requires around 10–13 kW of solar to charge reliably during a Perth day. Most older 6.6 kW systems were designed for grid export, not battery charging. Adding more panels is typically the most direct and cost-effective fix.

Many inverters do have available headroom, but not all. That's why we conduct a compatibility check before quoting. We look at your inverter's rated capacity, the current panel array, DC input limits, and any manufacturer restrictions. We only proceed with an add-on if the upgrade genuinely improves your system. If your inverter can't support more panels, we'll tell you plainly and explain your options.

This depends on your inverter's rated capacity, the number of available MPPT inputs, your roof space, and your network operator's export limits. During our assessment we calculate exactly how many panels your system can accept, and recommend the package that maximises your investment without exceeding safe operating limits.

Yes, and this is one of the most common reasons Perth homeowners add panels to an existing system. An EV charging at home can add 10–20 kWh to your daily electricity demand. Without sufficient solar capacity, that charging comes from the grid. A 10 kW or 13.3 kW add-on typically provides enough additional generation to cover most daytime EV charging, bringing your effective cost per km close to zero.

In most cases, no. Keeping your existing inverter is a key part of why add-ons are so cost-effective. If your inverter has sufficient remaining input capacity, the new panels simply connect to available MPPT inputs. In some cases where the inverter is at capacity, a small secondary inverter or micro-inverter array can be added. We'll walk you through the best option during your assessment.

Installation timelines vary depending on your roof layout and package size. Our licensed WA electricians work efficiently to minimise disruption to your household throughout. Same-week bookings are regularly available.
