Key takeaway
The upfront cost depends on your system size; typical savings on your electricity bills mean the system pays for itself over time.
What affects the cost
There is no single price for a solar and battery system, because every home is different. The cost depends mainly on how big a system your roof and energy use call for, and on how straightforward the installation is.
The main things that affect your price
- The size and shape of your roof
- The number of panels you need
- The capacity of your battery
- How complex the installation is
How much you could save
By using your own free solar energy instead of buying it from the grid, most households see a meaningful drop in their electricity bills. The exact figure depends on your system size and how you use energy, but the savings continue year after year — and grow whenever energy prices rise.
- Lower energy bills
- Use your own energy
- Protection from price rises

Frequently asked questions
How much does a system cost?
Prices vary because every home is different. A smaller system for a compact home costs considerably less than a larger system with a big battery for a family home with high energy use. The only accurate way to know is a free, no-obligation quote based on your roof and your energy habits.
What is the payback period?
The payback period is how long it takes for your energy-bill savings to cover the cost of the system. For most homes this is a number of years, after which the savings are effectively money in your pocket. Higher energy prices shorten the payback time.
Are there grants or financing?
Depending on your circumstances you may qualify for financial support, and there are flexible financing options to spread the cost. A quick eligibility check is the easiest way to see what applies to you — it only takes a few minutes.
