As it stands today, most home solar systems in Australia do not have a solar battery attached. This is mainly due to the question of whether it is financially worth it to have a battery added to your solar system. However as solar feed in tariffs have fallen in recent years and homeowners put greater value on things like power security and carbon emission reductions, the number of batteries being installed is increasing.
What Are The Main Benefits of a Solar Battery?
Buying a battery can deliver a range of benefits to your home:
- Energy bill savings: by storing surplus solar power in battery and using it in the evening, solar batteries help homeowners make further reductions on their electricity bills.
- Power Outages: most batteries have the capability to keep power operating to your home during a network black-out or power outage.
- Virtual Power Plants (VPPs): These VPP schemes enlist a group of batteries together to provide services to the grid. This means the VPP operator may occasionally take control of your battery, and pay you handsomely for the privilege
- Carbon Footprint: by getting your requirements from the grid closer to zero, you can reduce your carbon emissions by ensuring your are running from renewable energy sources.
Best Battery For Existing Solar Systems – Retrofits
If you already have a solar system installed, you might be wondering which is the best battery to add on and is there any restrictions based on what you have installed. In most cases, if you already have a solar system installed, you will need to find an ‘AC-coupled’ or ‘all-in-one’ battery which includes a built-in inverter. These types of batteries are compatible with almost any solar system as they converter the power back to DC to store in the battery themselves.
Some of the most popular AC-coupled solar batteries:
- Alpha ESS
- Tesla Powerwall
- Sigenergy
Read our reviews below to compare these and other options.
If you are one of the forward thinking customers who installed a ‘hybrid’ solar inverter then you will be able to install a DC-coupled battery. This is usually going to be a battery from the same manufacturer as your solar inverter. This will be a cheaper installation and will typically be able to be monitored through the same app.
