The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
At the heart of every solar panel lies the photovoltaic (PV) cell, the unsung hero responsible for transforming sunlight into electricity. These cells, typically made from silicon, a semiconductor material, are the workhorses that drive the entire process. But how does this conversion happen? Imagine a silicon atom like a miniature solar system.
Solar panels are mainly located on the roofs of homes and buildings and can generate electricity and heat water free of charge. In the Northern Hemisphere (including Scotland) solar panels work best when they face south. This lets them face towards the sun all day.
Solar panels are made from lots of solar cells. solar cell Solar cells are put together to make a solar panel. Made from a material called silicon, solar cells convert the light from the sun into electricity. You can see an example of solar cells on the top of some calculators.
The current generated by a single PV cell is miniscule. To produce usable electricity, multiple cells are interconnected and encased within a protective glass and frame, forming a solar panel. However, the electricity generated by these panels is direct current (DC), which most appliances cannot directly use.
Solar panels create no harmful gases, so it is very environmentally friendly. If the sun is shining on a solar panel on your house, you are able to use the energy for free, reducing electricity bills.
