How do batteries interact with solar panels?

Solar panels generate DC power, which can be used immediately or stored in batteries for later. Inverters convert it to AC for home use, boosting energy independence, cutting costs, and providing backup during outages.

Batteries and solar panels work together to optimise energy usage and storage in your home. Here’s how they interact:

How they work together

  • Energy generation: Solar panels convert sunlight into direct current (DC) electricity using photovoltaic (PV) cells.
  • Energy storage: The DC electricity generated by the solar panels is either used immediately to power your home or stored in batteries for later use.
  • Inverter role: An inverter converts the stored DC electricity in the batteries into alternating current (AC) electricity, which is used by most household appliances.
  • Energy usage: During periods when solar panels are not generating electricity (e.g., at night or on cloudy days), the stored energy in the batteries can be used to power your home.

Benefits of this interaction

  • Energy independence: Reduces reliance on the grid by using stored solar energy during non-sunny periods.
  • Cost savings: Lowers electricity bills by maximising the use of solar energy and reducing peak-time grid consumption.
  • Backup power: Provides a reliable power source during outages.

By combining solar panels with battery storage, you can improve your home's energy efficiency and reliability, putting you in control.

Daytime Solar Use
Tip Text / Subtext
The cheapest energy you have is direct from your solar panels. Run your high-energy appliances, like the washing machine, dishwasher, and EV charger, during peak sunshine (10 am-3 pm) to use this free power and save your battery for the night.

Beat the Peak!
Tip Text / Subtext
One of the most expensive times to buy electricity is the evening peak. Let your home battery, fully charged with free solar from the day, take over. By using your own stored energy, you can cook dinner and watch TV without paying those premium prices.
