Contact T&D Solar to discuss a solar power solution for your home and start receiving the benefit of clean, free electricity by converting the energy in sunlight.

Consider some of the advantages:

  • Reduce what you pay for electricity now and future proof yourself against rising electricity prices.
  • Reduce the amount of electricity used from the electricity grid and help protect the environment.
  • You may be eligible for the states feed-in tariff, which could mean additional savings (conditions apply).

How do grid-connected solar PV systems work?

Solar Photovoltaic (PV) panels are generally fitted on the roof in a northerly direction and at an angle to maximise the amount of sunlight that hits the panels.
Solar PV panels on the roof of homes generate clean electricity by converting the energy in sunlight. This conversion takes place within modules of specially fabricated materials that make up the solar panels.
Most suburban homes in Australia are connected to the electricity grid, which uses alternating current electricity (AC). The electricity generated by solar panels is direct current (DC) therefore grid-connected solar PV systems require an inverter to transform the DC electricity into AC electricity suitable for ordinary household needs. Houses with solar systems use solar power first before sourcing electricity from the grid.

How much power do solar PV systems generate?

The output of a solar PV system depends on many factors including its size, location, orientation and tilt. System sizes range significantly, however common household systems range from 1.5 kilowatts (kW) to 3.0kW.
The average daily production of a 1.5kW system facing true north, with a tilt angle of 20° in Adelaide is approximately 6.3kilowatt hours (kWh). A typical Australian house consumes around 18-21kWh per day so a 1.5kW system displaces an average of about 30% of the average electricity bill. Please note, solar panels produce more energy in summer than they do in winter and the above figures are estimates across a year.

SA Feed-in Tariff

South Australia operates under a NET feed-in tariff; a premium is paid for solar energy that goes back into the grid from your house (conditions apply - please refer to sa.gov.au site for details). Therefore if you have surplus energy generated by your solar panels, you may get paid for it; and if you use all of the energy you generate it will be offset against your normal electricity bill.
