Solar & battery installation
Solar & Battery Installation in Kallaroo
Westcoast Energy designs and installs residential solar and battery systems for Kallaroo and Perth’s northern suburbs, based on how your household actually uses energy.
Solar installation
Solar designed around your home.
A good system starts with how your household uses electricity, what your roof can support and where your plans are heading, not a standard package.
New residential solar installations
Complete solar PV systems designed around your electricity use and available roof space.
Learn more →Solar system upgrades
Replace ageing panels or add generation to an existing system, where the inverter, roof space and network rules allow.
Learn more →Solar system sizing
Sized from your usage, your roof and your plans. The biggest system that fits isn’t always the right one.
Generation and household use
We look at when your panels will generate and when your home uses power, so the design suits your day.
Solar inverter selection
An inverter matched to your electrical supply, your panels and any battery you may add later.
Future battery compatibility
Equipment and layout chosen with storage in mind, so a battery can be added later if it suits your household.

Battery storage
Store more of what your panels generate.
A home battery holds surplus solar energy so you can use it later in the day, when your panels aren’t generating. Whether it makes sense depends on your usage, your solar system and what you want the battery to do.
Home battery installation
Battery systems installed to suit your switchboard, your supply and your existing solar equipment.
Battery storage sizing
Capacity and output matched to your evening usage and how much surplus solar you actually have, rather than the biggest battery on offer.
Solar and battery integration
New solar and battery systems designed together, or storage added to an existing system through a compatible hybrid or AC-coupled setup.
Existing solar upgrades
A working solar system can often be kept. We assess its inverter and condition before recommending whether to keep it, modify it or upgrade it.
Backup power considerations
Not every battery provides backup in an outage. If it matters to you, the equipment and electrical design need to be planned for it from the start.

Featured project
A recent solar upgrade in Kallaroo.
We recently replaced an older solar system at a multi-storey home in Kallaroo. The original 28 panels (5.32 kW) were removed and 40 new panels installed across three roof faces, bringing the array to approximately 18.6 kW.
The property already had a hybrid inverter and battery storage in place. They stayed as they were, and the new array was designed to work with them. Installed capacity describes the size of the array, not how much electricity it will generate.

FAQs
Solar and battery questions
Quick answers to common questions. If yours isn't here, give us a call.
It depends on how much electricity your household uses, when you use it, how much usable roof space you have and what you might add later, such as a battery or an electric vehicle. We review these and recommend a size for your home. A bigger array isn’t automatically better, because the value depends on how much of what it generates you can use.
A battery stores surplus solar energy during the day so you can use it later, for example in the evening. How much it helps depends on how much surplus your panels produce, how much you use after sunset and the size of the battery. We look at these before recommending a capacity, and we don’t promise a particular saving.
Often, yes. Our Kallaroo project replaced 28 older panels with 40 new ones across three roof faces while keeping the existing hybrid inverter and battery. What’s possible for you depends on your inverter, your roof space, your electrical supply and network requirements, so we assess the existing system first.
Small-scale solar systems can qualify for incentives under the federal Small-scale Renewable Energy Scheme, which generally requires approved equipment installed by an accredited installer. Eligible home batteries installed with solar may also qualify for a federal incentive. The rules, amounts and eligibility conditions change over time, and some depend on your system and installation date, so we explain what applies to you when we prepare your proposal. The Clean Energy Regulator publishes the current requirements.
We start by understanding your usage, roof and plans, then design a system and quote it. Once you’ve agreed, we handle the installation and associated electrical work, subject to any required network approvals and site conditions, then test and commission the system and explain how to monitor it. Timing depends on the job, so we confirm it when we quote.
Usually they can, but it depends on your inverter and the battery. A hybrid inverter manages solar and storage in one system, while an AC-coupled battery adds its own inverter alongside an existing one. Not every inverter suits every battery, so we check compatibility before recommending anything.
Not automatically. Standard grid-connected solar systems shut down during an outage for safety. Backup power needs compatible equipment that has been designed and installed for it, and what it can run depends on the system. We’ll explain what’s possible for your home.
