Solar Batteries for every budget. 

You can add a battery to your existing solar system. If you find a compatible solar battery, it can be attached to your system and begin storing solar power. You must have a hybrid inverter (able to work with the panels and your new solar battery), or you will need a separate battery inverter. Note that due to new Whole of Site Compliance regulations in WA, Plico can only offer a hybrid inverter replacement battery system for eligible homes. 

You should avoid attempting to add a solar battery yourself. Solar systems contain delicate electrical circuits and are potentially dangerous. Leaving the installation process to qualified professionals ensures the battery is installed safely and effectively. 

For more details, have a look at our article about adding batteries to your solar system.

With the right installer, you can add a solar battery to your system anytime. However, common scenarios are if a battery needs to be replaced, a household wants to eliminate the risk of blackouts and load shedding, regularly charges an EV or wants to reduce energy bills. Homeowners who add a Plico battery also join our Virtual Power Plant and earn rewards for their energy, while contributing to a cleaner, more reliable grid and brighter energy future. 

The cost of adding a solar battery to your solar system varies based on the battery’s brand, size, and installation costs, as well as what rebates may be available.

Larger batteries have a greater storage capacity. However, larger solar batteries require more materials. Unfortunately, more materials mean higher costs and a higher retail price.

Different brands of solar batteries have differing features and quality levels. Higher quality materials, historical performance, and consumer demand are factors that dictate price differentiations. For example, expect to pay more for a solar battery with a high-efficiency rating. It pays to learn the average cost of a solar battery to get an idea of the quality level you can afford. Fortunately, Plico’s innovative financial model means that you can have an industry-leading solar battery for one low weekly instalment and no big upfront costs.

Installation costs vary based on the installer. Factors such as the installer’s desired price point, the current demand, the number of batteries you need to be added, if you need a new inverter or battery housing, and how far your household is from the installer’s location affect the installation cost. 

Once again, by becoming a Plico member, you can bypass the sting of these installation costs, as it’s included in your one low weekly instalment!*

The best way to learn if a particular retrofit battery is compatible with your existing solar system is to chat with an industry professional. A reputable provider and installer will know how compatible their retrofit battery is with your particular system. Plico can add a hybrid inverter replacement battery system if your solar is less than three years old and your home is single storey. This is due to new Whole of Site Compliance regulations in WA. 

Plico stands by its systems for a minimum of 10 years, so you can be sure your battery (and inverter) will perform as it should.

Yes, you can install additional batteries onto your solar system even if you already have a solar battery installed. Over time, you may have upgraded your solar system, increased your energy consumption or purchased an EV or pool, which means you want more energy storage capacity. You can accommodate this increase by installing an additional battery in your solar + battery system. Ideally, the additional battery you choose will be the same type as the battery you already have for the best compatibility. If you have ensured the battery is compatible, it is simple to expand the storage capacity of your solar system. 

Note that you may need additional battery housing infrastructure, depending on the battery upgrade. For this reason, modular batteries are a good way to future-proof your storage needs, as they fit neatly into the same battery housing.  

Batteries can be retrofitted onto an existing solar system, but there are some practices to avoid.

Firstly, consider the age of your solar system. Modern solar panels have an average lifespan of around 25 years. If the rest of your solar system is nearing the end of its warranty or performance life, upgrading your whole system makes more sense. You also need to consider the size of your solar system. Older systems are generally smaller in size and have limited capacity to charge a large solar battery. 

Secondly, don’t buy a battery that doesn’t fit your energy needs. The biggest battery is not always the best. It may not be necessary for your household and could result in storage capacity you never utilise (and higher costs). You also need to consider your system's ability, in terms of your solar panel capacity and inverter output, to charge a large battery. 

Thirdly, don’t stray from your budget. Everyone has a different financial situation, and your purchase should reflect yours. Decide what you can afford and shop with that number in mind. However, if you think your needs might change in the future then it’s a good idea to ask what the potential upgrade costs are. With Plico, you can pay your system off in easy weekly instalments.

You must consider the relevant factors when determining the right size battery storage for your solar system. These include your electricity consumption, your roof’s size and position, your solar panel capacity, inverter output and your budget.

You should upgrade a solar battery when its performance is no longer meeting your needs. There are a few situations where upgrading your solar battery makes sense.

Like all technology, solar batteries have lifespans and will decline in performance as they age. However, the better quality of your battery is, the slower this process will be and the longer it will last. Read our article on solar battery longevity for an in-depth look at how long solar batteries last.

Another reason to upgrade your solar battery is because of damage. A reputable provider will supply a warranty for your solar battery. Still, if yours is out of warranty or without a warranty, this is a great opportunity to upgrade your battery.

Plico provides ongoing support on all of its battery systems, so you have peace of mind that a Plico battery will work as intended by the manufacturer over your agreement period. Plico members can upgrade their battery at the end of their agreement period and continue enjoying 24/7 solar savings with a new battery!
