So you’re thinking of going solar? You’re in good company. Already more than 1.6 million Australian households and counting have taken control of their energy use and their power bills by generating clean, cheap energy from the sun. It’s nothing short of a rooftop revolution.
For an average Australian family home a 5kW solar power system is a relatively large system and should easily supply enough electricity. If you have a 5kW system and its not big enough then your home is using way above the Australian average kWh domestic consumption rate.
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 3kW solar system is now a very popular choice for residential solar installations in Australia selling for around $4,000 to $6,500 fully installed. There are cheap 3kW systems on the market but honestly its not worth the time and money to install one of these inferior systems.
In the southern hemisphere solar photovoltaic (PV) panels are usually mounted in a northerly facing direction to gain the maximum amount of sunlight possible hitting the surface of the panels.
The cost of deploying renewables across Australia is just a small proportion of electricity bills. By far the largest 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.
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 favoring 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.
