STCs or Small-scale Technology Certificates are a tradeable commodity created for eligible renewable energy systems and can be obtained for the value of the emissions reduction they create. Under the Federal Government’s Small Scale Renewable Energy Scheme, the STC value will be deducted from the total quoted price of the solar system, which in turn reduces the final price of the system, making the solar system more affordable.

Feed-in tariff is a payment in the form of credits, which customers receive from the power retailer for exporting the surplus electricity to the grid. It varies across states and territories, between retailers, and in some states, even across distribution networks. A minimum feed-in tariff is set every financial year and electricity retailers must pay these or higher.

In the event of a blackout, your solar PV system will automatically stop generating electricity due to safety reasons. This is a mandatory requirement in order to protect anyone working on the blacked-out grid. Once power is restored to the grid, your system will start generating electricity.

Yes, clouds can diffuse or block sunlight, which in turn restricts the amount of sunlight absorbed by the solar PV system. There will still be electricity generated but at a reduced output.

You can check the performance of your system easily as majority of the inverters have a built-in display that gives you live feed on the power being generated by the system or via web application on your mobile if your solar inverter is wi-fi ready.

Yes, but that comes at an extra expense as the installer will usually mount the solar panels on frames/mountings which are tilted so that rainwater can flow easily and not be trapped on the panels thus preventing algae from growing and not affecting the efficiency of solar panels.

Most Solar panels have a manufacturer’s warranty of 25 years while most inverters carry a minimum 5 year’s warranty.

The solar panels generally require truly little maintenance as they are self- cleaning when installed at a pitch that ensures rainwater runoff. In case, you notice bird droppings or dirty sections on the panels you may organise to have them cleaned so that the solar production is not affected.

The solar system only works with sunlight and its completely normal for the system to be non-functional when there is no sun. The system will again resume its operations on sun rise.

Once the solar system is connected to the grid, the owner will receive credits based on their utility from their power retailer for the excess electricity being exported back to the grid.

Yes, all our installers are fully qualified electricians with additional Clean Energy Council accreditation for the specific installation of solar power systems and carry all relevant insurance cover.

We only install high efficiency tier-1 panels and products approved by the Clean Energy Council (CEC) that meet Australian Standards. The Lists of approved products is also available on their website.
