Its now estimated that well over one million Australian homes are using rooftop solar photovoltaic (PV) systems to generate clean electricity for their daily power requirements. If you are in the market for a solar power system, then there are a few points to consider.

The cost of deploying renewables across Australia is just a small proportion of electricity bills. By far the most significant component of electricity bills is network costs (40 to 50 per cent of bills) – that is, upgrading transmission and distribution infrastructure such as poles and wires to handle rising peak demand and replace old equipment.

The 3kW solar system is now a popular choice for residential solar installations in Australia selling for around $4,000 to $6,500 fully installed. There are standard 3kW systems on the market, but honestly, it's not worth the time and money to install one of these inferior systems.

A 2kW solar power system is a sensible system size for an average Australian home that is usually empty during the day. Feed in tariffs being what they are, that is favouring the big greedy power companies makes using as much of your solar power more economical as the price of buying power from the grid is much higher than the feed-in tariff export price.
