Solar energy is energy that is derived from the Sun. The energy of the Sun’s rays can be converted into other forms of energy when they reach Earth. Solar energy, for example, can be produced and converted into heat or electricity. Solar energy generation is the process of converting solar energy into another form of energy. One type of solar energy generation uses photovoltaic or PV technology to generate electricity by absorbing the sun’s light, while the other uses solar thermal technology to generate heat by absorbing the sun’s warmth.
Solar energy is collected using photovoltaic cells, which are typically made of silicon, a nonmetallic element, when it is used to generate electricity. When exposed to light, photovoltaic cells can generate electricity. Photons, which are solar energy particles, are absorbed or reflected by photovoltaic cells as rays from the sun strike them. Other photons may completely bypass the cells. The electrons are released and channeled into an electrical current as the photons are absorbed.
Solar thermal technology entails using the sun’s rays to heat a liquid to extremely high temperatures. A collection device is used to collect and store solar energy in direct thermal collection systems. Collector systems come in a variety of shapes and sizes, but they all begin with solar panels that collect the sun’s heat. During the day, these panels are usually designed and positioned to absorb as much of the Sun’s heat as possible. Water-containing solar thermal collectors are housed within the panels, where the sun’s heat raises the temperature to a high level, and the heated water is then used to generate heat.
Some solar energy generation systems work in a back-and-forth manner. The sun heats a non-water liquid in this type of system. After that, the heat energy is transferred to a water tank.
Both types of solar energy generation have applications in the real world. It is possible to light an entire building, run appliances, and even cook with enough solar panels. Solar energy generation can also be used to heat an entire home or a swimming pool. Solar energy generation may even benefit the environment because it produces no pollution or noise. Unfortunately, solar technology installation can be expensive, and the weather can have a significant impact on the amount of energy available to a home or business.
