PV Solar Panels
#The sun provides the earth with enough energy in one hour to satisfy a years' worth of the world's needs.
# Shell Oil predicts that by 2040, 50% of the world's energy will come from renewable sources such as solar power. Many major companies like Shell run their own solar training courses.
# If you produce even more energy than you use, your utility company will buy it back from you.
# Solar power is not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing prices.
# Once your solar panels are installed, there is no more outlay! Its just savings. They are immediate and will last a lifetime.
How do photovoltaic (PV) cells work?
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.
PV cells come in a variety of shapes and colours, from grey "solar tiles" that look like roof tiles to panels and transparent cells that you can use on conservatories and glass.
The strength of a PV cell is measured in kilowatt peak (kWp) - that's the amount of energy the cell generates in full sunlight.
