Searching for a trusted Solar Installer Perth homeowners rely on? While your property’s solar panels may produce plenty of electricity during the day, your system might still rely on grid power when the sun goes down. Such instances prompt Australian households to consider batteries for their solar systems. According to the Clean Energy Council, over 268,000 home batteries were installed in 2025.
For many owners, the issue is that their solar systems do not match the timely demand of their consumption. That’s why getting a battery may help by storing excess daytime solar and making it available when your panels are producing less. So, if you are considering integrating a battery from your solar installer in Perth, these indicators may help you decide!
5 Signs That Indicate You Need a Solar Battery
Integrating a battery makes more sense when your solar generation, electricity use, and energy goals point towards energy storage. These five signs can help you decide whether getting the best solar battery is worth discussing with your installer in Perth.
You Regularly Send Excess Solar to the Grid on Daytime
Solar panels generate their highest output during the daytime. However, your household may not be able to maximise the use of electricity during this time. For instance, if your household is mostly away during the day, you could be exporting a substantial amount of generated solar instead of using it. This usage pattern matters because the excess energy could have been stored in a battery for later use.
Larger systems generate more daytime electricity, thus potentially creating more surplus for property owners to use or store. According to the Clean Energy Regulator, the average solar PV system installed in 2025 reached 10.3 kW. Having a battery backup gives you assurance during power outages.
So, if you consistently generate more electricity than you need, a battery storage and talking to a certified Solar Installer Perth expert can help you maximise solar and battery efficiency for your property.
Your Electricity Bills Remain High Despite Having Solar
Installing solar does not automatically eliminate your electricity bills. Your property may still acquire electricity from the grid whenever it needs more power than your panels are generating. Perth solar installers address this mismatch by adding a battery to store some of your excess solar and making it available for later use.
For example, imagine your panels generate excess electricity at noon while your home is relatively quiet. In the evening, your family could be running appliances, using lights, and using air-conditioning in the house. Without storage, you may spend more on grid energy at night.
Your Electricity Demand Peaks in the Evening
According to AEMO’s 2025 Quarterly Energy Dynamics report, distributed PV supply reached 61% of the National Energy Market (NEM) in 2025. Your business’s operating hours or your evening routine creates a timing problem in maximising your generated electricity. A battery can help shift some of that daytime generation into the evening, so you rely less on grid power.
For your own property, the good starting point is reviewing your household’s actual consumption profile before choosing a battery. A professional solar installer in Perth may assess when and how much electricity your property uses to recommend the right battery size for your system.
You Want More Energy Independence and Backup Power
You may also be considering a battery because you want greater control over your property’s electricity supply. Backup power can provide another reason to consider storage. Depending on the battery and installation configuration, you may be able to keep selected essential appliances operating during a grid outage.
For example, you might prioritise important electrical loads in your establishment. However, a battery does not automatically mean your entire property will remain powered during an outage. Your solar system installer needs to determine which circuits should receive backup power and whether the selected battery can provide the required output.
You Are Ready to Upgrade Your Existing Solar System
You do not necessarily need to replace your entire solar setup to add battery storage. If you already have solar panels, adding a compatible battery may get you more value from the electricity your system generates. However, your existing equipment needs to be assessed first.
An installer from the best solar company in Perth examines your system before recommending the right battery installation. This helps you stay aligned with the new requirements for solar and battery systems in Western Australia. This is also an appropriate time to address related electrical issues or arrange solar panel repairs where necessary.
