About Solar
The first semiconductor solar cell device was developed by Bell Labs in 1954. It converted only about 6% of light to electricity, but it was the birth of a new power source which is now beginning to play a major part in our electricity networks. The solar power industry has been growing at around 30% per annum for the last 20 years, with total world production of solar modules exceeding one gigawatt for the first time in 2007.
Summary Table This table shows some key figures for different system sizes. Each column is explained in more detail below. All values are for Sydney / ACT and are approximate only. Assumes an 'efficient house' consumes 10kWh/day. What is a kilowatt? Kilowatts, kW, are a measure of instantaneous power. Every load requires a certain…

Generate Electricity Electricity produced by your solar system will be subtracted from your electricity bill, generally at the same rate to what you pay or similar, depending on the size of the system and which electricity retailer you are with. The introduction of Feed in Tariffs in some Australian states and territories ensure that solar…

About Solar
Solar cells are made from a layer of semiconducting material, such as silicon, which has been doped with small traces of other elements in two or more layers. Light enters the cell and gives electrons enough energy to escape from the semiconductor and flow through an electrical circuit. This flow of electrons is electricity. How…

About Solar
Solar cells are connected together and encapsulated to form solar modules. The solar cells are generally sandwiched between a toughened glass front and a poly vinyl back sheet surrounded by an aluminium frame. While solar modules have traditionally been sized to suit lead acid batteries, with outputs of 12 volts, new grid connect modules tend…

About Solar
Grid connect photovoltaic solar power systems are the most cost effect way of using solar energy to power your home, school, office or commercial facility. They can be scaled up or down to meet anything from a portion of a household's power requirements to the power requirements of large industrial facilities. In a grid connected…
