Solar PV

Solar electricity systems capture the sun's energy using photovoltaic (PV) cells. These cells convert the sunlight into electricity, which can be used to run appliances and lighting.

PV cells don't need direct sunlight to work so your system will still generate electricity even on a cloudy day.

How do PV cells work?
PV cells are made from layers of semiconducting materials that emit electrons when exposed to sunlight. As the electrons flow across the semiconducting layers a DC current is produced. When cells are grouped together in panels, significant amounts on electricity can be generated.

Panels are normally fitted on a south facing part of your building – usually on the roof but there are other options such as walls or A-frames. The strength or rating of a PV panel is measured in kilowatt peak (kWp) – this is the amount of energy the panel generates in full sunlight.
