Solar Basics

solar basics, how_solar_power_works

Photovoltaic PV solar panels produce electricity directly from the sun’s energy. The Panels are connected to an isolating switch, then to an inverter which converts the DC power produced by the panels into AC power that can be used at home. The power is then channeled into the electricity grid.


The inverters we recommend are SMA and Fronius, which are both considered the highest quality in the world market.


How do Photovoltaic (PV) solar panels work?


In most Australian states, electricity produced by the panels is first used in appliances that draw power within the home during the day, including your air conditioner, refrigerator, microwave, etc.


Any excess solar power is exported to the grid. After which, the grid feeds electricity to the house during times when electricity consumption is greater than solar power production (e.g. during the night).


How do the benefits of solar panels work in different states?


In states with a net Feed-in Tariff, power produced by the panels first reduces your electricity bill at the standard rate. Excess solar power that is fed into the grid earns the premium Feed-in Tariff.


In states with a gross Feed-in Tariff, the metering arrangement is slightly different. All electricity generated by the solar power system flows out your solar power meter in your meter board (fuse box). The electricity you use in the house then either comes from the solar panels or the grid. Any excess solar power is used within the neighbourhood.


What happens to solar panels in a blackout?


In either case, during a blackout, the inverter disconnects itself from the grid in order to protect the lives of personnel working on the power lines. For this reason, a separate inverter and battery bank are required if you wish to have a back-up power supply. Most people purchase a standard system without batteries though. Please contact us if you wish to use a battery bank to be off the grid.


What Customers are saying about Gold Coast Energy

"Have just had a 2kW system installed on my garage by Gold Coast Energy, after being rejected by another company saying they could not do the install as my house had tin tiles. Thank goodness Gold Coast Energy made the effort to come out and come up with an easier option for us to be able to get Solar. Wonderful friendly communication and very helpful in explaining how it all works."
