Solar PV

Photovoltaics (PV) is the science of converting energy from the sun in to electricity.  Photovoltaic cells are constructed from layers of a semiconductor material (silicon) which are ‘doped’ using boron or phosphorous.  ‘Doping’ conditions the silicon, forming P type (positive) or N type (negative) layers.  These layers are then sandwiched together.  When a photon from the sun reaches the N type layer, it will release an electron in to the P-type layer, this flow of electrons can be captured and put to use.  In a PV panel, large numbers of cells are connected together to produce significant electric currents.

A wide variety of PV products are available on the market today from traditional rigid panels to thin-film, flexible technologies and glass integrated products.  There are currently more opportunities to exploit PV technology than ever before:

Autonomous systems can be used in conjunction with batteries to provide power for caravans, boats or field instrumentation.

Grid connected systems can be used to offset conventional electricity and improve the environmental performance of a building.  PV systems can be integrated in to almost any building from residential properties to large commercial buildings.  PV modules can be retrofitted to an existing building, or be integrated in to building facades right from design process. 

It is a common misconception that the UK climate is unsuitable for PV panels – this is not true.  Photovoltaic cells generate electricity even on a cloudy day.  All that is required is a suitable surface with southerly exposure.

RDES can design and supply a tailor made solution for any situation.  RDES are not bound to a particular manufacturer and will specify the right technology to fulfil a customers needs.
