What are solar PV panels?
Solar electricity systems capture the sun’s energy using photovoltaic (PV) cells. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
PV cells are panels you can attach to your roof or walls. Each cell is made from one or two layers of semiconducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced.
Photovoltaic systems utilise the suns energy to generate electricity. The main advantage with PV systems is that they only require daylight and not direct sunlight to work. Basically they convert solar radiation into electricity.
The solar PV panels can be either used by way of a battery store or can be connected to the main grid which can then be sold back. PV panels are extremely versatile they can be installed on or within rooftiles they can even be installed on the ground.
Solar PV systems can be fitted to most buildings providing the roof is strong enough to take the weightof the panels and also that there is loft access. It is advisable that they are fitted in a south facing area. It is recommended that atleast an area of 10m2 of panels are used and that also that there is no overshading on any of the panels as this can effect the efficiency of the system. This must always be taken into consideration when placing panels.
