Two types of rebates are offered by the State and Federal Government for Solar Installations.

  1. A rebate/discount while the initial purchase of the system
  2. The credit on the excess power generated by the solar and exported back to the grid, called as the “Feed In tariff”.
  • When a solar system is purchased, Small Technology Certificates (STC’s) are generated. 1 STC is created for every Megawatt of energy the solar system is expected to produce over the coming 11 years.
    A 6.6 kW system (approx 18 panels) will produce around 120mW worth of electricity over a 11-year period so you are entitled to 91 STC’s, which currently trade for around $38 each. This means you receive approx. $3500 in assistance when you purchase a 6kW Solar system.

The excess electricity produced by your solar system will be exported to your local grid. Your electricity retailer will be buying this energy from you on a rate fixed by them and they will be giving  you credit on your electricity bill.

Accessing Solar

The Feed In tariff and Small Technology Certificates (STC’s) is available to all commercial and residential buildings

  • Generally Planning approval is not required. A planning approval is only required for the properties governed by Strata agreement or if its heritage listed.

North facing roofs are the best location for the absolute energy production. However, panels can be installed on the roofs facing from east to west directions. So, don’t worry if you don’t have a north facing roof.

Solar systems can be installed in a flat roof or on tilting frames. A slight pitch is recommended to allow for water runoff and cleaning.

The system size needed for one’s house depends on several factors like:
  1. How many panels can be able to fit in the roof
  2. Depending on your usage and budget, small size systems won’t give you much result if your usage is higher
  3. If you intend to have a bigger family in future and spending most of the time at home, then its recommended to go for bigger sized systems.

We generally finish off our installations in about maximum of 2-3 weeks from the approval date.

How Solar Works?

The basic working of the solar energy system is by converting the sunlight into usable energy for your home. When the sunlight hit the panels, they generate Direct Current (DC), this DC goes into the inverter which converts this DC into Alternating Current (AC) which can be used in your home.

  • Generally, grid connected solar energy system consists of the following parts
    1. Solar Panels: The Panels are kept on the roof tops and they convert the sunlight into DC electricity and feed this DC into the Inverter.
    2. Inverter: The DC electricity produced from the panels reaches the inverter and then gets converted into AC electricity here, which energizes your home appliances.
    3. Bi-Directional meter: This meter records the energy taken from and sent back to the grid.
    4. Balance of System: This consists of the Mounting frames, cables, Circuit breakers, Isolators.

Yes. The Solar energy system produces electricity during the daytime which energizes your home and the excess electricity gets exported to your grid. The solar energy system does not work in the night-time, so currently you need electricity from the grid.

Yes. Additional panels may be added to your systems if you have a larger capacity inverter. If your inverter does not support the larger system, then an additional inverter can be installed near to the existing ones.

The output of the solar energy system depends on various factors listed below:

Solar panel Orientation: North is the best location for maximum solar production as this position receives sunlight throughout the day. If not, north we need split the panels in the west and east sides of the roof for optimum production. Installing panels in South direction is not recommended.

Roof Pitch: A roof pitch of 30 degree is optimal for solar generation.

Weather: Australia is blessed with one of the best weathers in the whole world for solar generation. Cloudy weather will have effect on the solar generation.

Shading: Shading of the panels will always influence the solar generation, so its always recommended to install panels where there is no shading.

You will be receiving bill/statement from your energy retailer. If you have exported more units to the grid than you have used from the grid, then you will be getting credits from your electricity retailer, in this case you don’t have to pay them. This credit amount will be mentioned in all your electricity bill/statement.

If your electricity consumption is not covered entirely from your solar then you will receive bill only for the units, you have used. The excess amount of exported electricity will be shown as credit in your bill.

No. If the voltage from the grid drops below a certain level, the inverter will shut down and will be running only once the certain voltage is fed into it from the grid. This is a requirement as the Electricity workers could be electrocuted if the solar is exporting energy to the grid while people are working.
