Solar Batteries| 4 Reasons Why You Should Get A Solar Battery


With government feed-in-tariffs reducing, is it time to switch to battery and take solar to the next level?

WA recently switched from a REB tariff system to a DEB tariff system to encourage WA residents to invest in solar and become more energy-autonomous.

But solar batteries have had a bad rap recently as high prices have discouraged even the most devoted solar fanatics away from the extra storage.

But why bag the battery when you can essentially:Tesla Battery

  • Reduce your electricity bills to $0.
  • Power your home entirely by the sun and reduce your carbon footprint.
  • Avoid time-of-use rates and grid prices altogether.
  • Use your solar energy at night.

So, let’s take a look at the top 5 reasons you should get a solar battery.

1. Stop Paying For Electricity

One of the most obvious reasons for getting a solar battery is so that you can reduce your electricity bills.

If you use the majority of your solar energy during the day and switch to stored solar battery energy at night you essentially do not need to buy any extra electricity from the grid and you can reduce your electricity bills exponentially.

2. Solar Batteries Allow You To Use Your Solar Energy At Night

One significant benefit of installing a solar battery is that you can now utilise your solar energy at night!

The excess solar energy that is not used up during the day is captured and stored in your battery for times when your solar input isn’t great, like at night.

Another benefit of the battery is that you can opt for blackout protection! If your street goes dark having a battery that supports blackout protection means that you can still run your home as normal.

There are two types of blackout protection:

  • Whole-of-house protection.
  • Selected appliance protection.

3. Avoid Peak Hour Electricity Rates By Using Battery

If your energy provider works on a time-of-use rate or ‘peak hour’ rates your electricity price will spike during popular energy use times.

These ‘peak hours’ usually occur during the late afternoon and evenings leaving your energy bill much to be desired.

By using a solar battery you can draw from your solar reserves during these peak times, meaning you can skip these raised rates altogether!

4. Solar Batteries Reduce Your Carbon Foot PrintReduce-your-carbon-footprint-with-solar-batteries

Grid electricity is still partly sourced from fossil fuels. The less reliant you are on fossil fuels the better your carbon footprint will be. By installing a battery you can reduce or entirely remove your need for electricity from the grid.

By utilising only energy generated by sunlight you can actively reduce CO2 emissions by 100 tons within 30 years!

Ready To Install Rooftop Solar and Battery?

The best way to get solar panel and battery options that suit you is to compare quotes from multiple, experienced CEC accredited installers in your area. This is to ensure you are getting a system that is tailored to your needs and property, not what the installer wants to sell. Solar Market partners with top solar installers across Australia and will match you up with 3 local solar installers so you can start saving sooner.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
