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

We cover Beaconsfield, Fremantle, Hilton, North Fremantle, O’Connor, Samson, South Fremantle, White Gum Valley & the Whole Perth Metro.

Of course. If your solar power supply produces excess energy, you can simply feed it back to the grid, getting credit for future electricity bills. This is known as a ‘Feed-In Tariff’. You can expect to get around 5c – 8c per KW/H. The major electricity companies are only offering 5c per KH/H. You might even get up to 10c from smaller retailers.

Ask your solar installer like Formula Sun as to who supplies the highest Feed-In Tariff when you are selling back AC from your solar power supply. Solar power is a great way to go green and save some cash. You won’t get rich, but you will make your investment back, make a little on the side, and help the environment.

The Australian Renewable Energy Agency (‘ARENA’) plays a role in the regulation of solar energy in Australia. The Clean Energy Council (‘CEC’) also plays a direct role. This non-profit organization accredits installers of solar panels so they are installed the right way. This allows the customer to take advantage of solar tax rebates.

The majority of solar panels are usually about 15% – 17% efficient on average. The best solar panels will have efficiency levels of around 22% or so. The efficiency of a solar panel is actually called its performance. The performance of a solar panel is tested under Standard Test Conditions (‘STC’). These conditions are a 25°C temperature and an irradiance of 1,000 W/m2. You can use the performance of a solar panel to determine how much watts each cell would generate under standard conditions.

Solar photovoltaic (‘PV’) is much more common than solar thermal. Solar thermal converts heat to usable energy, while Solar PV converts sunlight to usable energy. Solar thermal is used in niche and large scale industrial applications but not for residential housing or commercial businesses.

With our interest-free finance options, you can save in many ways. You can cut down on electricity bills while simultaneously taking advantage of smart finance to make the process more convenient and affordable.

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 this with an example as follows.

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 of only using the electricity produced by your rooftop solar supply.

You may save around 15 units per day. This 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.
