Is a solar battery worth it for your Tasmanian home?
-
Your solar system produces more energy than you use during the day.
-
You use a significant amount of electricity in the evening or early morning.
-
You are on a time-of-use tariff where electricity is expensive at peak hours.
-
You want backup power and are considering a system designed for the circuits you need.
When it may be less useful
-
Your current solar generation is fully used by your daytime appliances.
-
You rarely use power during peak evening periods.
-
The upfront cost does not yet align with your long-term financial goals.
-
Your home energy needs are already covered by a very low flat-rate tariff.
Understanding Off-Peak and Peak Savings
A battery can help you use stored solar electricity in the evening instead of buying electricity from the grid. If you have a time-of-use tariff, the difference between peak and off-peak rates can also affect its value. The result depends on your tariff, electricity use, solar surplus, battery capacity, efficiency and installed cost.
Stored solar can reduce grid electricity use, but a battery may not cover all of your evening demand.
Match the battery to your evening electricity use
Do you have extra solar?
A battery needs excess generation during the day to charge. We assess if your current panels produce enough to fill a battery.
What is your current tariff?
Understanding whether you are on a flat rate or Time of Use tariff is crucial for calculating your potential battery savings.
Key questions to ensure you choose the right battery for your Tasmanian home.
Selection Checklist
When do you use power?
Batteries are most effective if you use significant power after the sun goes down, especially during peak tariff times.
What are your future plans?
Planning for an Electric Vehicle or shifting to all-electric heating? Your future energy needs help determine the battery size.
