With South Africa’s electricity supply under strain, many people are choosing Solar Energy to power homes and businesses because of its many advantages. Solar Energy is energy provided by the sun that is converted into thermal or electrical energy. It is the cleanest and most abundant renewable energy source currently available.
The energy is collected through direct sunlight, so even when there are clouds that seem to be blocking the sun, the Solar Energy will continue to refill. One of its greatest advantages is that you will never run out.
The energy source has become so popular that it is common to see Solar Panels on the roofs of many homes in Cape Town. Solar panels are devices that convert light into electricity. One panel is made of many small solar cells. Each of these cells uses light to make electrons move. The cell is made up of two different layers that are stuck together. The first layer is loaded with electrons, so the electrons are ready to jump from this layer to the second layer. That second layer has had some electrons taken away, so it’s ready to take in more electrons.
When the light hits an electron in the first layer, the electron jumps to the second layer. That electron makes another electron move and so on. It is the sunlight that starts the flow of electricity.
