Photovoltaic Systems

Solar electricity systems, usually referred to as 'Photovoltaic' or 'Solar PV', come in one of two basic forms; 'off-grid' and 'grid-tied':

  • Off-grid systems are typically used to provide power to remote buildings that do not have access to mains electricity.  The electricity generated is stored in a bank of batteries so it is available for later use. 
  • Grid-tied systems are applicable to more general domestic and commercial use. The solar panels are connected via your consumer unit (or fuseboard) to the National Grid. This means that any excess electricity produced is exported for others to use, for which you receive payment (details are on the Benefits page).
The main components in a solar PV grid-tied system are the solar panels and a box of electronics called an 'inverter' which converts the electricity the panels produce into a form which is compatible with the National Grid.  An additional electric meter, the 'generation meter' shows how much the system produces.  You provide your FiT payer with readings from this and they then work out how much they need to pay you.  The diagram above illustrates the typical configuration of a domestic solar PV system.
An example of a domestic inverter is shown on the right; they are typically smaller than wall mounted gas boilers, unless it is a large commercial version.  They come in different power ratings to suit the size of the system being installed.
Software design tools are used to work out which inverter best matches the solar panels and to take account of any shading issues which can affect the performance of the system.
