Solar is for everyone

There are a lot of misconceptions about solar power. Misconceptions like: solar is only for the rich, solar is not worth the investment because of the “low” Feed-in Tariffs [FiT], solar is not for renters or you won’t live your home long enough to make your investment in solar back. These misconceptions could be costing […]

Why should I get a solar battery system?

Battery systems for solar energy are still a highly debated topic. There are many good discussion points for both sides of the argument at this point, but much of the evidence is tilted towards the reasons why you should get one. If not now, then definitely in the future. Let’s explore why. Save Money Perhaps […]

Different ways to save with solar

There is lots of discussion around the fact that solar panels, and batteries, can save Australian homeowners lots of money, but the real question is, how? How does it work so that your energy bills are reduced, or even so that you can make a profit? How Can I Reduce My Energy Bill? For those […]

Yes, SA’s battery is a massive battery, but it can do much more besides

On Friday December 1,  the “world’s largest” lithium-ion battery was officially opened in South Australia. Tesla’s much anticipated “mega-battery” made the “100 days or it’s free” deadline, after a week of testing and commissioning. Unsurprisingly, the project has attracted a lot of attention, both in Australia and abroad. This is largely courtesy of the high […]

Battery storage looking up

In an effort to avoid the increasing energy prices in Australia, and the consistent power outages across the country, many people are exploring the concept of battery-storage for solar power on their homes.  Yet the move towards battery-storage has been a slow one, mainly because of the high price and uncertainty of the system. But […]

Australia Leads Energy Storage Boom

Amid the craze that has been battery storage for solar energy, Australia looks set to lead the way. The country has been named in a group of eight that are set to undertake significant structures in the storage of solar energy, which will see market increase exponentially by 2030. Similarly, to the growth of the […]

Solar Batteries: Are They Worth It?

There is a lot of discussion this year around the benefits of installing a battery device to household solar panel systems. In essence they are a great idea, storing energy to save the environment as well as household costs and excess electricity. But is the investment worthwhile at this point in time, when the system […]

What’s the net cost of using renewables to hit Australia’s climate target? Nothing

Australia can meet its 2030 greenhouse emissions target at zero net cost, according to our analysis of a range of options for the National Electricity Market. Our modelling shows that renewable energy can help hit Australia’s emissions reduction target of 26-28% below 2005 levels by 2030 effectively for free. This is because the cost of […]

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.
