Solar battery storage is a game-changer for homeowners looking to maximise their solar energy use. By storing excess solar power, you can reduce reliance on the grid, lower energy bills, and increase energy independence. But how do solar batteries work, and are they right for your home? Here’s everything you need to know.
What is Solar Battery Storage?
A solar battery stores surplus electricity generated by your solar panels. Instead of sending excess power back to the grid, the battery saves it for later use—such as during the evening or on cloudy days. This helps you make the most of your solar energy and reduces dependence on electricity suppliers.
How Does a Solar Battery Work?
- Solar panels generate electricity during daylight hours.
- The battery stores surplus energy rather than exporting it to the grid.
- Stored energy is used when needed, such as in the evening or during high-demand periods.
- If the battery is full, excess power may still be exported to the grid under schemes like the Smart Export Guarantee (SEG).
Key Benefits of Solar Battery Storage
- Maximise self-consumption: Use more of your solar energy instead of sending it to the grid.
- Lower electricity bills: Reduce the amount of electricity you buy from your supplier.
- Energy security: Keep your home powered during grid outages (if using a backup-capable battery).
- Reduce carbon footprint: Further cut your reliance on fossil-fuel-generated electricity.
- Optimise time-of-use tariffs: Charge your battery with cheap off-peak energy if needed.
Choosing the Right Solar Battery
When selecting a solar battery, consider:
- Capacity (kWh): How much energy the battery can store. A typical home battery ranges from 5kWh to 15kWh.
- Depth of Discharge (DoD): How much of the battery’s capacity can be used before needing a recharge.
- Lifespan & Warranty: Measured in charge cycles, most batteries last 10-15 years.
- Compatibility: Ensure the battery works with your existing or planned solar PV system.
- Backup Power: Some batteries provide power during outages, while others do not.
Is Solar Battery Storage Worth It?
The cost of a solar battery varies depending on size and technology, but prices are steadily decreasing. To determine if it’s a good investment, consider:
- Your typical energy usage and savings potential.
- Available incentives and grants.
- Electricity tariff structures (e.g., off-peak charging options).
