Frequently Asked Questions

1.  Why do I still need electricity from the mains?

Your solar system may not always collect enough electricity to cover your daily power requirements therefore you can still import electricity from your mains. Your power consumption and the size of the unit will affect how much electricity is collected however on days when there is too little sunlight and during the night your system will automatically switch to the mains.

2.  How effective is a solar system in terms of value for money?

Australia is world famous for its sunny climate however we do not always best use our abundance of sunlight. Sunlight is a natural clean energy resource and once you pay the initial outlay for the solar system to be installed all the electricity you collect is absolutely free. Your solar system lifespan is over 25 years so imagine how much it could reduce your household running costs over this time.

3.  Where else can panels be placed?

The optimum place to install your panels is a north/west facing roof however is this is not possible we can also install your solar panels on sheds, verandas and pergolas.

4.  What if I have a flat roof?

Roof mounting systems can be installed to angle your solar panels at an adequately slanted position so that they can still collect the maximum electricity from the sun.

5.  How will I use the electricity generated from my solar system?

The electricity collected from the solar system is converted from direct current (DC) to 240V alternating current (AC) through the inverter. Once it has been converted into AC it is then fed back into your house or into the electricity grid. The credits you receive from your power will depend on your state's Feed In Tarrif structure.

6. Will a solar system cover all my electricity requirements?

Factors such as the size of the system, the location of your home, types of appliances and household consumption will all influence the electricity requirements. Our qualified installers can design and install a system that best suits your needs so that you obtain the best result from your system.

7.  What happens at night?

The solar system only produces the electricity through the collection of sunlight. Therefore, at night no solar panel system is able to produce solar electricity so the household will obtain power directly from the mains. However during the day the collected electricity is still fed back into the grid.

8.  What happens on a cloudy day?

On sunny days your solar system will obtain the best possible electricity collection, however on cloudy days the panels will not collect the same amount. You can expect the panels to gather around half the output that would be achieved on a sunny day. If the electricity for a cloudy day is not enough to cover the household requirements, the system will use power directly from the grid.

9.  What happens during a black out?

During a black out all solar systems will automatically switch off and re-connect once electricity has been restored to avoid any safety issues that may arise for the utility workers repairing the line.

10.  Does the system come with a warranty?

Our panels and inverters are sourced from the world's most reputable solar manufacturers. All our panels come with a 25 year performance guarantee to resist water, salt and pollution corrosion along with weather extremes such as hail and storms. Our inverters are built to the highest European standards and each are encased in weatherproof housing, backed by a 5 year manufacturer's warranty that can be extended to 7 or 10 years at an additional cost.

11.  Can I add more panels to my system later?

A number of our systems have the ability to upgrade, however this all depends on the inverter capacity. For more information on your options phone 1300 BE SOLAR.

12.  How do I know what size is right for my home or business?

The size of your solar PV system will depend on; the physical unshaded area available for the installation of panels; how much you are prepared to spend; and what portion of your electrical consumption you wish to generate.

To help determine what size system will give you the best output to meet the requirements of your home or business please contact one of our helpful Beacon Solar representatives on 1300 BE SOLAR (237 652) or email 

13.  What is a typical household's consumption?

A typical Australian house consumes around 18 kilowatt hours (kWh) per day so a 1-2kW system displaces an average of 25-40% of your average electricity bill. Solar panels produce more energy in Summer than they do in winter.

14.  Will I need a new meter?

Once your solar power system is installed you may require a new meter. If you have a traditional accumulation meter (with spinning disk) this will need to be replaced with an interval meter or smart meter. This is because an accumulation meter does not record the energy you export to the grid or the electricity you import from the grid. An interval meter or a smart meter provide half hourly readings of the electricity you consume and the surplus electricity you generate. The new meters are provided by your electricity provider at an additional cost.

15.  What happens after my solar PV system has been installed?

After your solar PV system has been installed and if you wish to receive your relevant Feed In Tariff, you will need to enter into an agreement with your electricity provider to access your state's Feed In Tariff. This will also include the installation of a smart meter if not already installed.
