How Solar Battery Storage Works: Everything Bristol Homeowners Need to Know
Adding a battery to your solar panel system lets you store unused electricity and use it when you need it — at night, during peak tariff times, or even in a power cut. But how exactly does it work? In this guide, we break down solar battery technology and how it benefits homeowners in Bristol.
What is Solar Battery Storage?
Solar battery storage systems capture excess energy your panels generate during the day and save it for use later. Without a battery, that extra power would be exported to the National Grid. With a battery, it stays with you.
How the System Works
- Solar panels convert sunlight into DC electricity.
- An inverter turns DC into usable AC power for your home.
- Extra electricity not used is stored in a solar battery.
- When the sun sets, your home draws from the battery instead of the grid.
Benefits of Solar Battery Storage
- Reduces your electricity bills even further
- Increases energy independence
- Provides backup during outages (for some systems)
- Helps avoid peak rate charges (especially with TOU tariffs)
