Solar Panels

What Panels

The cost of a solar panel is determined in part by:

  • its capacity (in Watts),

  • the physical size,

  • the brand,

  • quality of materials,

  • the durability / longevity (or warranty period)

  • and any certifications the solar panel might have.

Government Rebates

SA Solar feed-in payments There are two types of feed-in tariff

  1. the retailer feed-in tariff available to anyone with eligible solar photovoltatic (PV) system.

  2. the distributor feed-in tariff, also know as the solar feed-in scheme - only available for eligible solar PV systems that were connected to the grid before 30 september 2011.

  • AGL through that site appear to give 12.4 cents per KWh exported - that will be key to getting the most out a system NEED TO CONFIRM THIS

System Eligibility

  • need to meet safety standards

  • need to be connected to electricity grid through an import/export meter - which SA Power Networks will install

    • need development approval - recommends an electrician complete your behalf - see link above for form

    • may need to pay for digital meter to track energy usage

    • the generator will determine the connection process eg. inverterse no greater than 30kW, inverters greater than 30kW but no greater than 200kW, inverters greater then 200kW

Some info from choice on [solar panels

  • the higher each panel's nominal panel power rating and actual power output - the fewer panels you will need - or more power you generate

  • each panel is about 1.6 square meters

  • average cost across Australia capital cities for 5kW system is $5100

Solar system size (kilowatts) Avg daily system output (kilowatt-hours) 1.5kW - 5.4kWh 2kW -7.3kWh 3kW- 10.9kWh 4kW- 14.4kWh 5kW- 18.2kWh 7kW- 24.5kWh 10kW*- 36.3kWh


  • our typical usage per day ~ 30 kWh

  • 5kW solar system gets chucked around a bit but that's in terms of 20kW per day.

  • physical size ~ 1.7m (L) x 1.2(W) x 0.4m (H)
