Grid connected solar panel systems are connected to the electricity supply grid. An inverter converts DC low voltage power generated by the solar panels to 240V AC household supply. The smart meter also manages how much electricity is drawn from or fed back into the grid. When excess “Green” electricity is fed into the grid, the meter ticks backwards, so the household only pays the difference between what is fed and drawn.

This depends on your roof space and the size of the inverter. If you have sufficient roof space and additional capacity in the inverter you could increase the size of your system. Or you could add a second system to your roof. Please note: At this time, the solar Feed-in Tariffs in each state have limits on the system size which to they apply. Increasing the size of an existing solar power system could affect your eligibility for a Feed-in Tariff. Please call us for further information.

Since this depends on how long approval takes, it varies state-to-state. South Australia currently has the fastest meter approval and installation timeframe of 1-2 weeks. Western Australia is the slowest at about 4-8 weeks.

It's hard to say about average installation time without knowing the size of solar power system. Bigger the system, longer the time it require to be installed. Let's take 5 kw system for installation which takes around 3-5 hrs, start to finish.

The amount of roof space required depends on the size of the system. For example, a small 1.5kW system requires 12m² of roof space. This is ideally an un-shaded and north-facing part of the roof. The system is modular and can be arranged in a way that best suits the roof.
