If the power is out in your area you do not need to touch your solar PV system, it will Resume normal functioning once the power is returned to your area.

No, your solar PV system will not export any excess power back to the grid. You are better off leaving your power on so your system can earn money by exporting to the grid.

You will probably never have to clean them. They should self-clean in the rain. The exception to this is:

a. If your panels are flat.
b. You live in a very dry area.
c. You have a really stubbornly soiled panel due to moss, dead animals, particularly sticky bird poo etc.

If your solar production does drop – then there may be something on the panels that requires cleaning. The best way to find out is a visual inspection.
Safety warning! If you don’t feel confident on the roof and poking around near electrical wiring, get a professional; solar systems produce deadly voltages.

Yes, but with a reduced efficiency. Expect your panels to produce 10-40% of their rated capacity on an overcast day.

A feed-in-tariff is the amount your electricity retailer reimburses you for any electricity your solar PV system produces that you don’t consume and is instead fed back into the grid.

STCs (small-scale technology certificate) are government incentives that help reduce the cost of installing your solar PV system. The value of STCs your system receives differs depending on its size.
To be eligible for STCs, your solar system must be installed by Clean Energy Council accredited installers. You can be assured that Cola Solar only use CEC accredited installers.

If you have noticed a change in your energy savings, 9 times out of 10 its usually a reasonable explanation rather than being your system is faulty. Consider whether these apply to you.

  • Has your consumption increased?
  • Has your energy rate gone up?
  • Have you bought new appliances?
  • Are you using inefficient appliances?
  • Are new structures or trees shading your panels?

If these don’t apply to you and you are worried that you PV system is not operating efficiently, fill out the service enquiry form and we will contact you.

A general shutdown procedure is as follows:

  1. Turn off either the “Solar Supply Main Switch” located in the Switchboard or the “AC ISOLATOR” adjacent/below the inverter.
  2. Turn off all ‘PV ARRAY DC ISOLATOR(S)” located adjacent/below the inverter.


Start-up Procedure is the reverse of the Shutdown Procedure.
