It is considered a clean and efficient energy. Solar thermal energy is nothing more than the generation of heat from solar energy, and that can be used either to cook our food, to heat water for domestic consumption or simply for the production of mechanical energy, and with she, the electric.
To better understand how this type of energy is produced, we must know the parts that make up these devices responsible for transforming UV rays into solar thermal energy.
For example, solar thermal energy collectors, we can classify them as low, medium and high temperature collectors. In the case of the low temperature collector, the collector is a piece used to heat water, while the medium temperature collectors can heat both water and air. On the other hand, high-temperature collectors concentrate sunlight with the use of specially designed mirrors or lenses, and these are used to heat water to such a temperature that large turbines are used to generate electricity with the generation of steam. at an industrial level.
It is said that due to its convertibility process, solar thermal energy is much more efficient than photovoltaic solar energy. So, let’s answer the question how is solar thermal energy produced?
Very well, let’s pay attention, so that we get an idea about the process of generating solar thermal energy, the solar collectors that we had previously named are responsible for capturing all possible solar radiation, depending on their already specified capacities. From this point on, the process of converting solar energy to thermal energy begins, through various systems.
Once the solar energy has been collected, the connected solar collectors have the mission of transforming the energy received into thermal energy, increasing the temperature of the fluid that circulates through the installation.
Solar thermal energy accumulation
When we have obtained the thermal energy, it goes to storage in an energy accumulation tank for later use, that is, the hot water that we have obtained through the collection system, is led to a storage place.
Accumulation is always necessary since the need for hot water, for example, does not always coincide with those moments in which there is a lot of radiation, before which we must accumulate as much thermal energy as possible in the form of water, in order to use it. as needed.
Generally, a thermal energy storage system is made up of one or more hot water tanks and their storage must always be proportional to the estimated consumption and cover the demand for hot water for at least two days.
Distribution of solar thermal energy
Once the heat-carrying medium is heated, we can also transfer this thermal energy to other colder sources, using all the elements intended for the distribution of the heat-carrying liquid and conditioning for consumption, for example pipes, control unit, pipes, pumps. , expansion vessels, valves, steam traps, among others.
The generation of solar thermal energy is certainly a fairly simple and developing process that screams loudly in the energy market, for its ecological, clean and efficient qualities.
