How much do solar batteries cost?

Solar battery price might seem prohibitive, but the right system can save you a lot of money. Find out how much they cost and what impacts the price.

Solar power is a fantastic choice for anyone wanting to reduce their power bill and be kinder to our planet, but truly maximising its potential requires a key addition: a solar battery. But, the question remains: how much does a home battery cost?

I know you came here for a quick answer, so here it is. But please keep in mind that the price can vary depending on a number of factors.

  • A 5 kWh Enphase battery costs about $9,000 installed
  • A 13.5 kWh Tesla Powerwall battery costs about $16,000 installed

Of course there's no one-size-fits-all answer when it comes to solar battery price but if you read on, we'll explain the ins and outs so you can make an informed decision when speaking to the range of suppliers out there.

Things that impact the price of battery installation

Just like solar panel systems, several factors impact the cost to install a battery in your home:

Battery Capacity: Measured in kilowatt-hours (kWh), capacity determines how much solar energy your battery can store. Larger capacities store more energy but cost more upfront. Winki will assess your energy needs to recommend the perfect size for you, but at the end of the day, it's up to you. A larger battery means you can run more appliances if the power goes out and you'll have better solar utilisation during the night or on a cloudy week.

Brand is the second big factor: This usually correlates with quality. You get what you pay for, and with batteries, it is especially important to know what you're getting because a malfunction can be dangerous. That's why we only use the highest quality batteries in your home. It is important to consult an expert when choosing a battery, and ensure you only use reputable accredited installers.

Installation Costs: The complexity of installation can affect the price. Winki's experienced technicians ensure a smooth and efficient installation process.

Government Incentives: Solar Victoria offers a $8,800 interest-free loan to help with the cost of installing batteries in your home.

Other considerations when choosing a battery

System Compatibility: Ensure your chosen battery seamlessly integrates with your existing solar system and inverter. Winki prioritises compatible, high-quality batteries to optimise your solar setup.

Warranty: A longer warranty provides peace of mind, ensuring coverage for repairs or replacements within the warranty period.

A word on payback period of solar panels (PBP)

Payback period is the other of the two most important numbers when considering the financials of investing in a solar battery system. Payback period is the amount of time that it takes to make back the money on an investment. For example, a solar system that costs $6,000, and saves you $2,000 per year will have a payback period of 3 years. So here, we can see that changing the battery system cost, or changing the amount of money it saves on your energy bill will both influence the payback period of solar.

We've spoken about things that can impact the install cost. Here are some things that will alter the PBP:

Feed-in tariff: This is what you get paid for your excess solar that goes into the grid. This means you get to make money on the solar you don't use.

The size of your solar system: larger systems can keep you battery topped up and allow you to make the most of it. But there's a sweet spot - no point in going too big.

Your energy consumption habits: Homes that do use a lot of energy at night will get an enormous saving on their energy bill by investing in a larger battery to get them through the night.

The cost of grid electricity: Areas where grid electricity is more expensive (it seems like that's everywhere nowadays) will get an even bigger saving by not having to pay those high prices.

Smart device technology: Modern devices are able to optimise the use of the solar power you produce during the day, whether it's used to power your home, charge your battery, charge your car, or sold to the grid. Finding the best use for your solar power at any given moment means you maximise savings from your battery.
