Perth is known for long sunny days, which makes rooftop solar a smart investment. But many homes produce their highest solar output during the middle of the day, while their greatest energy use happens in the morning or evening.

That is where battery storage can make a real difference.

A solar battery stores excess solar power generated during the day. Instead of sending unused energy back to the grid, you can keep more of it for your own use later. Solar batteries allow households to store solar energy for use when it is needed most, such as at night or during peak demand.

For Perth families and businesses, that can mean:

• Using more of your own solar power
• Reducing electricity bills
• Improving energy independence
• Supporting EV charging plans
• Helping protect against outages, where backup capability is included
• Making your solar system work harder for you

Solar battery storage is not just about technology. It is about lifestyle, comfort, confidence, and long-term value.

Installing a battery is not the same as plugging in another appliance. A battery system connects with your solar panels, inverter, switchboard, utility meter, and monitoring system. It needs to be designed and installed safely by experienced professionals.

At PME Solar, we provide solar battery installation and storage in Perth for residential and commercial properties. Whether you want to install a new battery, upgrade an old unit, replace a malfunctioning system, or add storage to an existing solar setup, our team can help.

Our installation process includes:

• Site assessment to check available space, system layout, and safe battery placement
• Energy usage review to understand when and how you use power
• Battery recommendation based on your property, goals, and budget
• Professional installation by skilled technicians
• System testing to confirm safe and correct operation
• Monitoring setup so you can track battery charge, energy generation, consumption, and grid interaction

We keep the process clear from the first conversation through to installation and handover.

In simple terms, a solar battery stores electricity for later use.

Your solar panels generate power from sunlight. That energy is converted into usable electricity for your home or business. If your system produces more power than you need at that moment, the extra energy can be stored in your battery instead of being exported to the grid. Solar power is converted from sunlight into DC power, then passed through an inverter to become usable AC power, with excess energy stored in the battery for later use.

That stored energy can then help run:

• Lights
• Fridges and freezers
• Televisions and devices
• Home office equipment
• Pool pumps
• Air conditioning, depending on system capacity
• Business equipment
• EV charging, where the system is designed for it

The result is a smarter home or business that uses more of the clean power it already produces.

Many people start researching batteries because they want lower bills. That is a great reason, but the benefits go further.

A professionally designed battery system can help you:

Reduce grid reliance

The more stored solar energy you use, the less electricity you may need to buy from the grid.

Use solar power at night

Without a battery, your solar power is mainly used while the sun is shining. With a battery, you can keep using stored solar energy after sunset.

Prepare for rising energy demand

If you are adding an EV, running a home office, or using more electric appliances, battery storage can help your energy system keep up.

Improve backup options

Some batteries can provide backup power during outages, depending on the product, installation design, and backup circuits included.

Support a cleaner WA energy future

Batteries help store renewable energy and can support grid stability by balancing supply and demand.

For households and businesses, battery storage is about making solar more useful, more flexible, and more valuable.

PME Solar offers solar battery storage options from leading brands, including Tesla and Sungrow.

Tesla Powerwall

The Tesla Powerwall is designed to store solar energy for use when the sun is not shining or during an outage, where backup functionality is configured. PME Solar notes that the Tesla battery has a 13.5 kWh energy capacity, can be floor or wall mounted indoors or outdoors, includes a 10-year warranty, and can be monitored through the Tesla app with real-time production and consumption information.

What this means for you is that you can store solar power during the day, use it later, and monitor your home energy from your phone.

Sungrow Battery

PME Solar also offers Sungrow battery options designed for PV self-consumption, backup power, load shifting, and household applications. Sungrow options listed by PME Solar include a 13.5 kWh energy capacity, indoor or outdoor installation, floor or wall mounting, web and mobile monitoring, and a 10-year warranty.

In simple terms, a Sungrow battery can help you use more of your own solar power and manage energy more efficiently across the day and night.

Battery size matters, but bigger is not always better. The best battery for your property depends on how much electricity you use, when you use it, and what you want the battery to achieve.

We look at questions such as:

• How much solar energy does your system produce?
• How much power do you use after sunset?
• Do you want backup power capability?
• Are you planning to charge an EV?
• Do you have a pool, air conditioning, or high-use appliances?
• Is your property residential or commercial?
• Are you planning to expand your solar system later?

A smaller household may need a different battery setup from a large family home, workshop, office, or commercial site. Our job is to recommend a practical system that suits your needs, not simply the largest option available.

Perth battery installations need to be planned with Western Australian energy rules in mind.

From 1 May 2026, new requirements apply to many new and upgraded rooftop solar and battery systems installed in the South West Interconnected System. These include requirements around inverter capacity, remote disconnection and reconnection capability or export limiting, and compliance with AS/NZS 4777.2:2020.

Emergency Solar Management rules also apply to certain new and upgraded rooftop solar PV and battery installations, with systems required to be capable of being remotely turned down or switched off in emergency situations. These requirements are intended to support the stability of the electricity system and do not interrupt customer power supply.

That may sound technical, but we make it easier.

With PME Solar, you get practical guidance on:

• Battery compatibility
• Inverter requirements
• Export limits
• Backup gateway installation
• Monitoring systems
• Grid interaction
• Future upgrade options

We design for Perth conditions and WA requirements, so your system is installed with care and confidence.

The Small-scale Renewable Energy Scheme, known as the SRES, is an Australian Government initiative that supports investment in renewable energy systems through Small-scale Technology Certificates, or STCs.

The Australian Government’s Cheaper Home Batteries Program is delivered through the SRES and supports eligible households and small businesses with discounts on small-scale battery systems connected to new or existing rooftop solar. From 1 July 2025, the program has supported a discount of around 30 percent on eligible battery systems.

Eligible solar batteries must meet program requirements, including capacity rules and relevant Australian standards. The Clean Energy Regulator states that eligible batteries must be between 5 kWh and 100 kWh in nominal capacity, with STCs claimable for the first 50 kWh of usable capacity.

WA households may also be able to access the WA Residential Battery Scheme, which provides rebates and no-interest loans for eligible residential batteries. The WA Government states that applicants may be eligible for rebates of up to $1,300 for Synergy customers and up to $3,800 for Horizon Power customers, with eligibility requirements including Virtual Power Plant participation.

We can help you understand what may apply to your situation and how available incentives may affect your quote.
