How much does solar cost to buy and install?

Endeavour Energy does not supply or install solar power systems, and does not make any recommendations on the systems to buy or the installers to employ, other than requiring licensed electrical contractors to undertake the electrical works and requiring equipment to comply with Australian Standards.

 

The cost of purchasing and installing a solar power system is subject to competitive market rates and any government incentives or subsidies available at the time of purchase.  Cost can vary significantly and we recommend you obtain several quotes to ensure value for money.

 

The total system price will depend on the size of the system, type of solar panels and inverter, ease of installation, meter installation and any rebate or discount that you may receive from government schemes.

 

For more detailed information on solar power systems, please see the Clean Energy Council Consumer Guide to Solar PV.

How much will a solar power system generate?

The following table has been produced as an indicative guide using a standard of a 1 kilowatt solar power system as a guide.  The Office of the Renewable Energy Regulator calculator identifies an average system will produce approximately 1400 kilowatt hours of electricity per year.  The amount of electricity your solar system will generate depends on the size of the system, the amount of solar energy it receives, the orientation and tilt of the panels and the reliability of the system.

 

Size of solar system	Approximate kWh generated per year
1kW	1,400
2kW	2,800
3kW	4,200
4kW	5,600
5kW	7,000
6kW	8,400
7kW	9,800
8kW	11,200
9kW	12,600
10kW	14,000

 

Please note that generation can vary between any two individual installations depending on various factors including:  cell and panel efficiency; inverter efficiency; daylight hours; cloud cover; altitude and the seasonal angle of sunlight incidence.

 

Solar tariffs

Eligible residential and business customers in New South Wales can receive a solar bonus credit under the NSW Solar Bonus Scheme for solar energy fed into the network.

 

For customers who are not eligible for the NSW Solar Bonus Scheme, electricity retailers may offer a range of tariffs for solar electricity fed into the network depending on your location, the size of your solar power system, meter configuration and eligibility for government schemes.

 

Where the tariff for solar energy fed into the network is lower than the tariff for consumption energy taken from the network, a net metered arrangement should provide a better economic return than a gross metered arrangement, by reducing the amount of energy taken from the network.
