Photovoltaics is the direct conversion of light into electricity. Some materials exhibit a property known as the “photoelectric effect” that causes them to absorb photons of light and release electrons. An electric current results (DC) that can be used as electricity.

For solar cells, a thin semiconductor wafer is specially treated to form an electric field, positive on one side and negative on the other. When light energy strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of an electric current -- that is, electricity.

Multiple modules can be wired together to form an array. PV modules and arrays produce direct-current (DC) electricity. In On-Grid systems, the modules are normally connected in series electrical arrangements to produce the required voltage and current combination. An Inverter is then used to convert the DC current to AC so that it can be utilised in your home or business and/or fed back into the Power Grid.

With the current yearly increase in power bills set to continue, PV Systems are a real opportunity to reduce home and business costs and to help the environment.
