Obviously, everyone is aware about the solar energy that normally derived from the rays of the sun. Based from the facts, the sun provides as much as 5000 times energy to the earth. But how is solar energy used? Maybe, there are people who do not know the purpose of this solar energy and the advantages provided by it from their day-to-day life.
Solar energy has utilized its radiant energy from the sun. The solar power is specifically refers to the sunlight conversion of electricity either through the use of some experimental technologies like solar ponds, solar chimneys, and thermoelectric converters or by some concentrating solar thermal equipments and photovoltaic.
To give you an idea on how is solar energy used, listed below are some of its purposes:
• Shading and solar energy shall be given an important consideration that can be used for building design. The thermal mass is the one that is used for the conservation of the heat while the light of the sun is the one that delivers the building. Whereas, the solar water heaters provide a domestic hot water and heat swimming pools. In terms of agriculture, the powered solar cells are the ones that expand the growing season of the greenhouses. While the evaporation ponds clean the waste streams of contaminants and can be used to harvest the salt.
• The methods of solar disinfections and distillation have produced portable water for many people around the globe. Some of the simple applications included are clotheslines and the solar cookers that focus sunlight for pasteurization, drying and cooking. Many of the sophisticated technologies have magnified the light of the sun for industrial chemical production, metal smelting, and material testing with high-temperature. A variety of prototype solar vehicles provide sea transportation, air and ground.
A country that is recognized to have the highest count of sunny seasons every year is the South Africa. That is why is considered as the most appropriate place around the world that can use to have the solar power energy. So how is solar energy used by some of the Africans? The photovoltaic sell can be used through the light of the sun that is used to create an electric current. It is not actually the heat of the sun that provides electric current as everyone thought. The power of electric current may therefore depend on the amount of energy provided by the sunrays. However, the efficiency of the photovoltaic will decrease when the cell is extremely heated by the sun due to the resistance that builds up the material. These photovoltaic panels therefore will not work efficiently to some places that have an extreme warm climate. Summertime in South Africa is very hot, so these panels will work less efficient during this season.
