Why More Sydney Homeowners Are Installing Solar Batteries
Traditional solar systems export excess electricity back to the grid during the day. Unfortunately, feed-in tariffs have fallen significantly in recent years, making exported solar power far less valuable than it once was.
A solar battery changes this by storing excess solar energy for later use.
Instead of exporting electricity for a small feed-in tariff, you can use your stored energy during the evening when electricity prices are highest.
Benefits include:
- Lower electricity bills
- Increased solar self-consumption
- Reduced reliance on energy retailers
- Protection from future electricity price increases
- Backup power options during blackouts
- Greater energy independence
- Smart energy management through mobile apps
- Reduced carbon footprint
- Increased value from your solar system
For many Sydney homeowners, a battery is now the missing piece that unlocks the full value of their solar investment.
How Does a Solar Battery Work?
During daylight hours, your solar panels generate electricity.
Your home uses the power it needs first.
Any excess energy is then stored in your solar battery instead of being exported to the grid.
When the sun goes down or energy usage increases, the battery automatically supplies stored electricity to your home.
This process allows you to use more of your own renewable energy and buy less electricity from the grid.
Modern battery systems operate automatically and can be monitored through smartphone apps that provide real-time information about energy production, battery charge levels and household consumption.
