Discover the uses of solar energy. Solar energy has been around for a long time but only recently has it started to be used in industrial applications. The focus has been on homes and small commercial properties, where people want to be more self-sufficient and save money on their monthly energy bills. One way this is done is by using passive solar design, which aims to make as many of the smallest appliances and systems as possible passive solar designs, and thus are not using any fossil fuels in their operation. The most common use is in heating water, with the cold water coming from the pumps and hot water coming from the sunlight.
Solar energy is beneficial in several ways, solar heat is especially beneficial to people who live in very cold countries, where access to sunlight is limited. The sun is the primary source of life on Earth, so using solar energy is really useful to in several different ways. Solar energy can also be used to generate electricity with photovoltaic cells, which convert light directly into electricity, and is used for heating water, air conditioning, heating furnaces, for remote control and surveillance, for military communication equipment and for telecommunications. The most common use is in heating water, with the cold water coming from the pumps and hot water coming from the sunlight. You could also heat up your house by using solar panels and a battery bank to store the energy for use during the day.
Solar energy can also be used to generate electricity by using photovoltaic cells on your roof, or even on poles in the field near to your house. Photo Voltaic systems work best near the equator where there is a lot of sun hours, but this is not to be limiting as you can move them anywhere. These systems are also known as solar ventilation systems, because the sunlight is used to create electricity through photo-voltaic cells that are then arranged in a circuit to make electricity. The amount of electricity generated by this process is dependent on the sunlight, the power of the photovoltaic cells and the amount of salt in the fluid being heated (salt is very important).
The uses of solar energy is many and varied, and the future will show us many more uses for it.
