How much does it cost to install a solar battery in your Melbourne home or business, and will it really save you money?
Solar batteries are the hottest thing on the market at the moment, and they’re going in on every scale from giant solar farms to individual households. Having the ability to keep solar power for the when the sun isn’t shining makes it possible to run on solar power throughout the day and night, no longer relying on the grid at certain times.
As Australian electricity prices climb, it’s no wonder we’ve been installing a lot of them!
Battery Storage: The return on your investment
Battery storage starts at around $5,500 for 2 x 1.2kWh Enphase AC Batteries with the Enphase monitoring system, fully installed. This option makes it easy for you to start small and expand your storage later, with additional batteries costing approximately $2,000. Unlike larger batteries, this system doesn’t function as a backup power source if the grid goes down.
Powerwall 2 is the very popular Tesla 13.5kWh battery. It’s a sleek gadget with a new-car finish that sits snugly against your wall and can be controlled from the equally slick My Tesla app on your phone. It’ll currently cost you from roughly $13,000, and comes with full backup capability in case the grid goes down. These batteries are also available bundled with new solar systems if you don’t yet have yours.
How much battery storage is right for you and how quickly your battery will pay itself back depends on not only how much solar power you can generate and how much of it you can consume, but also when you can consume it. If your energy consumption across the day looks like the graph up above (dark blue), then a battery could be a great fit for your household. If you’re home all day and consume a lot of your electricity during the daytime, a battery is going to make less of a difference and you may be better off with an oversized solar power system.
It’s also possible that you’ll generate enough extra power during the day to cover the cost of your overnight power; the average feed-in tariff is around half the average cost you pay per kWh, so you’ll have to generate around twice what you need to use.
