If you installed solar panels five or ten years ago, your goal was probably simple. Reduce your electricity bills and make better use of the sunshine on your roof.
For many homeowners across The Hills District, that’s exactly what happened. But a lot has changed since then.
Electricity prices have increased, feed in tariffs have reduced and many households now use far more electricity than they did when their solar system was first installed. Air conditioning, swimming pools, home offices and electric vehicles have all contributed to higher household energy demand.
As a result, more homeowners are asking the same question.
Can I add a battery to my existing solar system instead of replacing everything?
In most cases, yes.
Adding a battery allows you to store excess solar energy generated during the day and use it later when your household needs it most. Rather than exporting that energy back to the grid, you can use more of the electricity your solar system already produces.
For many households, it’s one of the most effective ways to get even more value from an existing solar system.
Why Are More Homeowners Adding Batteries?
Battery technology has improved significantly over recent years, but the biggest change isn’t the technology itself. It’s the way we use electricity.
Electricity prices continue to rise
Electricity remains one of the largest ongoing household expenses for many families.
While nobody can predict what electricity prices will do in the future, many homeowners are looking for ways to reduce their reliance on the grid and take greater control of their energy costs.
A battery allows you to store more of the energy your solar system generates, helping to reduce the amount of electricity you need to purchase from your retailer.
Feed in tariffs aren’t what they used to be
When many homeowners first installed solar, feed-in tariffs were far more generous than they are today.
While every electricity retailer is different, the amount paid for exporting solar energy is often significantly lower than the cost of buying electricity back from the grid later that evening.
Instead of exporting that excess energy, a battery allows you to store it and use it yourself when the sun goes down.
For many households, that’s becoming a much better use of the solar energy they generate.
Our homes use more electricity than ever before
Think about how much your household has changed over the past few years. Many homes throughout The Hills District now have:
- Ducted air conditioning
- Swimming pools
- Home offices
- Electric vehicles
- More people working or studying from home
Most of that electricity is used in the late afternoon and evening, long after your solar panels have stopped producing power.
A battery helps bridge that gap by storing energy generated during the day for use later when your household needs it.
You Probably Don’t Need a New Solar System
One of the biggest misconceptions is that adding a battery means replacing your existing solar system.
In most cases, that’s simply not true.
Most existing solar systems can be upgraded with battery storage. The best approach depends on your current equipment, particularly your inverter and overall system design.
In many cases, a battery can be added to work alongside your existing solar system, although some installations may require additional equipment or minor electrical upgrades to ensure everything works together safely and efficiently.
The first step is a site assessment, where we review your existing system, discuss your energy goals and recommend the most suitable battery solution for your home.
How Does a Battery Work with an Existing Solar System?
Without a battery, any solar energy your household doesn’t use immediately is generally exported back to the electricity grid.
Imagine your solar system generates plenty of electricity while everyone is at work or school. That excess energy is exported because there isn’t enough demand in the home at the time.
Later that evening, your family comes home, turns on the lights, cooks dinner, watches television and runs the air conditioning.
Instead of using the electricity your roof generated earlier that day, you’re buying electricity back from the grid.
A battery changes that.
Rather than exporting all your unused solar energy, the battery stores it for later use.
For many households, this increases the amount of solar energy they use themselves, helping to reduce their reliance on grid electricity and get more value from the solar system they already own.
Is Your Solar System Ready for a Battery?
Every home is different, which is why there’s no single battery solution that suits everyone. Before recommending a battery upgrade, we assess several important factors, including:
- The age of your existing solar system
- Your inverter make and model
- Your current electricity usage
- How much solar energy you’re exporting
- Your switchboard configuration
- Whether backup power is important to you
This allows us to recommend a battery solution that’s designed around your home and your energy needs, rather than taking a one size fits all approach.
