Everything you need to know about solar batteries for your Perth home.
A home battery (also called a solar battery or energy storage system) stores excess electricity generated by your solar panels during the day, allowing you to use that energy at night or during power outages.
Think of it as a large rechargeable battery for your home, similar to the battery in your phone or laptop, but scaled up to power your entire household.
Your solar panels generate electricity during daylight hours. Any excess power not immediately used by your home flows to the battery.
The battery charges throughout the day, storing energy in lithium-ion cells, similar to your phone or electric car battery.
At night or during peak pricing periods, the battery automatically supplies stored energy to your home, reducing grid reliance.
Use your own stored solar energy instead of buying expensive electricity from the grid during peak times. Perth households typically save $1,000-$1,500 per year from self-consumption alone (based on 10kWh battery, 20kWh daily usage, A1 Midday Saver tariff).
Keep essential appliances running during blackouts. Critical for medical equipment, food preservation, and comfort during Perth's occasional storm-related outages.
Reduce reliance on the grid and protect yourself from rising electricity prices. Become more self-sufficient with your energy needs.
Synergy Battery Rewards pays 70¢/kWh during 15-25 activation events per year. For a 10-13kWh battery, expect $100-180/year from VPP. DEBS peak exports (10¢/kWh 3-9pm) add another $50-100/year. The bigger win is self-consumption savings.
Homes with solar and battery systems are increasingly attractive to buyers, potentially adding $10,000-$20,000 to your property value.
The most popular choice for home batteries, offering the best balance of performance, lifespan, and cost.
