When a battery is useful
- 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 (peak times).
- You are on a time-of-use tariff where electricity is expensive at peak hours.
- You want the peace of mind of backup power during Tasmanian blackouts.
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 doesn't 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
The biggest financial benefit of a battery is price arbitrage. In Tasmania, electricity rates are often much higher during 'peak' times when everyone is home and using power. By storing your excess solar energy during the day, you can use it during these expensive evening peak periods rather than buying power from the grid. This effectively 'shifts' your free solar energy to when it is worth the most, significantly reducing your reliance on high-cost peak electricity.
Key Insight: A battery makes sure your most expensive power usage is covered by your own free solar energy.
Energy Independence & Backup
A solar battery offers a safety net during grid outages, keeping your essential lights and fridge running. While it provides valuable peace of mind and reduces reliance on the grid. It is important to understand that most residential batteries are designed for daily use rather than powering a whole home indefinitely during a blackout. It's about smart backup for what matters most.
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.
