13. Energy Council How does solar PV work Solar Photovoltaic PV panels are generally fitted on the roof in a northerly direction and at an angle to maximise the amount of sunlight that hits the panels Solar PV panels on the roofs of homes and businesses generate clean electricity by converting the energy in sunlight This conversion takes place within modules of specially fabricated materials that make up the solar panels It is a relatively simple process that requires no moving parts In most cases solar panels are connected to the mains power supply through a device called an inverter Solar panels are different to solar hot water systems which are also mounted on household roof tops but use the heat from the sun to provide hot water for household uses The technology to convert sunlight into electricity was developed in the 19th century but it was only in the second half of the 20th century that development accelerated behind the need to provide reliable supplies of electricity in remote locations from satellites in space to outback Australia Solar panels have been installed on the rooftops of houses and other buildings in Australia since the 1970s Currently there are more than 100 000 solar panel systems safely and reliably delivering clean electricity across Australia Consumer guide to buying household solar panels photovoltaic panels Grid connected solar PV systems Most suburban homes in Australia ar
