Solar energy is heat and radiant energy from the Sun, which is captured using a wide range of ever-changing technologies including solar thermal power, photovoltaic, solar heat, solar architecture, solar heating and artificial photosynthesis. It is an infinite source of clean, renewable energy with no negative impact on the environment. The sun will always shine, it is not going anywhere and the technology to harness its power will always be in development. Solar energy will be cost effective, reliable and sustainable. The only problem we have today is that the technology is not yet in full development, but the promise of a greener, cleaner future is not lost and solar energy has a lot of potential to meet our needs and become the norm in our homes, offices and industries.
Solar energy has different uses depending on where it is used. It can be used to heat pools and homes, use as electricity in electric vehicles (EVs), provide hot water and even convert rainwater into water and energy for our gardens. The heat from the sun is available in the form of radiation that can be captured and used to produce electricity in panels or solar panels. The heat can be stored for later use in a battery system for example, which can then be used immediately when required. The technology is here to meet all of our future energy needs, especially as a means of reducing our carbon footprint. The technology is here to stay and shows no signs of slowing down.
Solar thermal collectors are used for collecting the sun’s energy either directly by using mirrors to focus the heat on insulated tubes or indirectly by using heat exchangers to convert the energy in the sun into electrical energy. Solar photovoltaic cells are used to convert the sun’s rays into direct current or D.C. electricity using an array of photovoltaic cells (PV) which are then connected to a host of electrical components, creating a voltage. This electric energy can then be used to power our home appliances and other electrical devices.
