Get more from renewable energy with added solar battery storage

To understand what size of solar battery you require, you’ll need to work out your average daily energy consumption. This will help you understand how much power you actually use each day, and therefore how much you might need to store for those cloudier days or evenings.  

You can start working this out yourself with a few easy rules of thumb, which you can find here in our battery size guide. Or, talk to our team today and we’ll help you work out what battery will work best for your unique property. 

Yes, solar batteries with blackout protection are designed to work when the grid goes down – helping to ensure you still have power when the grid fails. If this is a concern for you, let's chat about your options during your consultation. 

This is partially up to you, though we’ll make some recommendations once we’ve viewed your property. 

Some property owners store their solar batteries in their garage, as modern batteries like the Tesla Powerwall 3 are designed to be sleek and compact, fitting in anywhere they’re placed. 

Batteries can also be stored outside if there’s no suitable indoor area, though they would need to be protected from harsh weather. 

How long a solar battery can hold its charge depends on the battery, and the amount of energy being stored. We would expect most modern batteries to be able to hold their charge for several days, if not weeks, assuming low usage. 

As for their lifespan, solar batteries should last several years to more than a decade (depending on usage, climate and maintenance, among other factors). 

Yes, most modern solar batteries are stackable – allowing you to add more capacity over time. If you find that your battery isn’t holding enough power to keep your appliances running during evenings or periods of instability, talk to us about adding more capacity. 

You won’t stop generating solar power just because the battery is full. If your solar battery reaches capacity, the extra charge will be diverted away from your property and ‘exported’ to the grid. In many cases, such as if you’ve joined a VPP network, you may be able to sell your excess energy back at a premium rate or receive a billing discount in return.
