How Brendan Cut His Quarterly Electricity Bill From $800 to Under $400

Watch: Brendan Cut Quarterly Electricity Bills From $800 to Under $400

Before installing battery storage, Brendan says his electricity bill was around $800 per quarter. He now reports paying under $400 — a reduction of more than half based on the figures in his testimonial.

Store energy during the day and use it at night

Brendan's reason for installing a battery was straightforward: store solar electricity during the day and use it at night. Without storage, excess daytime solar energy is generally exported to the grid. A battery allows more of that electricity to remain available for the household after solar production falls.

The monitoring app changed how energy was used

Brendan highlights the convenience of seeing when his battery is charging or full. That information helps the household decide when to run the dishwasher, washing machine and other flexible loads. Running selected appliances during strong solar production may power them directly and preserve stored energy for later.

Investment and payback

Brendan believes the system is worthwhile and expects it to pay for itself quickly. Actual payback periods vary significantly. They depend on:

• installed system cost;
• electricity rates and feed-in tariffs;
• daily and seasonal consumption;
• solar production;
• battery utilisation; and
• future energy prices.

A credible assessment should use the home's own electricity data rather than a generic saving claim.

A long relationship with Solar Battery Group

Brendan says he has used Solar Battery Group since 2009 and describes the business as easy to work with. That long-term relationship adds a different type of proof to the campaign: repeat trust, not only a single installation-day review.
