A residential solar system could be anywhere between 3kW and 20kW depending on your requirements, existing metering connection (1, 2 or 3 phase), solar approval (approval to connect solar) and roof space (including its orientation).

A typical 1kW solar PV module produces up to 4.5kWh/day on a bright sunny day, but on average, a 4.2kWh/day per kW of solar is estimated for energy and saving assessments. 

At PROBEC, we only offer Tier 1 solar modules which was Clean Energy Council (CEC) approved. The solar rebate can only be claimed against CEC approved products (panels, inverters, and batteries). CEC continuously updates the list of approved products, click here if you want to see the updated lists on CEC website.

Whether you are looking for a 3kW or up to 20kW solar system on your property, each property has its unique requirements to install the solar system. Following are some of the key factors which should be considered:

  • Electricity bill
  • Type of roof (Tile, Colourbond, Decramastic, Terracotta, and other)
  • Roof orientation (ideal roof is facing north, but east and west could be used if there are restrictions on north side – please note that there will be about 12% daily production while installing on eastern and/or western roof).
  • Electricity meter (1, 2, or 3 phase): A maximum of 5kW/phase can be exported to the grid. So, if you have 3 phase meter then you might be eligible for 15kW export.
  • Solar feed-in tariff: It is important to understand and compare solar feed-in tariff before deciding on the size of solar system. Click here to read more about solar feed-in tariff.
  • Payback time: The payback back time should be less than five years depending on your electricity bill before solar and size of solar system.
  • Government incentive on solar (solar rebate): The rebate on solar depends on the size of total PV installed. Click here to learn more about solar rebate.
  • Meter box/switchboard: The meter box and/or switchboard might need an upgrade depending on State’s requirements once a solar system is installed. The metering team might not connect your solar with grid if a mandatory and required upgrade is not conducted. Therefore, you might need to consider some extra cost on your solar if your meter box and/or switchboard requires an upgrade.
