FAQSThere has never been a better time to install solar panels in Perth

With our high savings returns and interest-free finance options we are proud to offer you a deal that will lower your electricity costs and pay off your new solar system at the same time. Let us know your average Synergy bill and we will work out your savings for you.

As far as waiting for new solar technologies, despite many press releases and articles on innovative new solar breakthroughs, the largest and probably most important solar development in the past 4 years has been the gradual decline in the cost of installed solar systems and the increased reliability.

Coupled with this has been the integration of wifi technology into all inverters and greatly improved solar portals for the monitoring and management of your solar system. All of the solar inverters we recommend now come with a dedicated solar app for your phone and devices.

There is no other investment you can make that will offer you the returns that a residential or commercial solar system will. If you have a bill over $350 per 60 days, we can offer you a zero deposit package and guarantee your Synergy savings will be greater than your repayments. In a few short years the system will be completely paid for and will generate you a lifetime of free electricity.

Every solar job is different, you may have a huge electricity bill with power-hungry teenagers or already be environmentally conscious. The larger your Synergy bill the more you have to save with a Solar System.

The vast majority of your savings with a Formula Sun solar system come from buying less electricity from Synergy. It’s easiest to explain with an example:-

The average Perth Synergy Bill is 22 units per day. With the right size solar system, you should be able to cut out all of your daylight electricity usages, instead only using the electricity produced by your rooftop solar supply.

You may save say 15 units per day, that equates to $1,480 per year, additionally, if you have a large solar array you will be able to export some solar electricity to Synergy, they currently pay around 7 cents per unit exported, that would be around another $300 per year.

There is some danger of the Federal Government reducing the generous Renewable Energy Target subsidy scheme which currently subsidises over half the cost of your Formula Sun solar system. It’s not that there are any plans for this to happen but politically it could happen very quickly.
