Understanding Solar Photovoltaic

Solar photovoltaic is a renewable energy source

Renewable energy source

Solar photovoltaic - or simply Solar PV - is a renewable energy source which uses photovoltaic (PV) cells in modules (commonly referred to as panels) to convert sunlight into DC electricity. This is then converted into useable AC by an inverter. By using our PV Kit Builder, we can help you design your domestic system with everything from the Solar PV modules to the fixing systems and inverters. For large scale commercial and industrial installations, contact us about our Power Performance Packages.

Solar PV

Solar PV systems convert light into electrical power. They range in size from a few square centimetres, for example on calculators and watches to systems of hundreds of square metres made from interconnected modules that form an array. Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction. An array of solar cells converts solar energy into a usable amount of direct current (DC). The DC is carried through wiring to an inverter, which converts the current to mains AC (alternating current) which is connected to the property’s main electricity supply.
