How it Works

    Q. What does a typical solar power system consist of?

        A typical grid connected solar energy system consists of the following components:
        Panels – The panels convert sunlight into DC electricity and then feed this electricity to the inverter.
        Inverter – The inverter converts the electricity produced by your panels from DC electricity to AC electricity which is what your appliances use. The inverter also records the electricity produced and on some models, can communicate with your computer.
        Bi–directional meter – Your meter records energy drawn from and sent back to the grid.
        Mounting System – This is what connects your system to the roof.

    Q. Do I still need electricity from the grid?

        Yes. Your solar system generates electricity during peak daylight hours. Any electricity produced during this time that is not consumed will be sold back to the grid. During the night when your solar system is not working, you will draw electricity from the grid.

    Q. Can I monitor the solar system?

        Absolutely. All systems that Excel Power installs have the ability to be remotely monitored.

    Q. What happens on cloudy days?

        Your system will still produce electricity during cloudy days however production will be less than on sunny days.

    Q. If my energy requirements increase, can I upgrade the system?

        Yes. Additional panels may be added to existing systems where a larger inverter has been installed. Where a larger system is required that is not supported by the existing inverter, an additional inverter can be installed next to the existing one.

The Equipment

    Q. Is the system installed by qualified electricians?

        Absolutely. Our expert installers are qualified licensed electricians and are our full-time employees - we don't subcontract our work and never will.

        Furthermore, Excel Power is accredited by the Clean Energy Council of Australia for the design and installation of your system. For more information, go to

    Q. Is there any system maintenance involved?

        There is minimal system maintenance required over the life of the system. You may be required to hose down the panels from time to time to remove dirt. The panels will self clean when it rains. We can complete a panel clean and a system audit for a small fee.

    Q. Can I insure my system?

        Yes. The system can be covered under home and contents insurance. Contact your insurer for further details.

    Q. Do I need a new meter?

        If you have an old spinning disc meter, you will require a new bi-directional meter. Ask one of our sales consultants for the procedures involved and rates to change your meter.

The Environment

    Q. How will I be benefitting the environment?

        Producing energy via a solar energy system helps the environment by reducing the need to burn carbon emitting fossil fuels such as coal and gas.
