The heating of water and the environment through solar energy is now a reality established on the market and it is interesting to talk about it. It is achieved by installing solar thermal systems. Solar panels that produce hot water by exploiting the radiation of the sun saved with a solar thermal system that is truly remarkable. The panels consist of a flat surface or a series of tubes containing a liquid which reaches a temperature ranging from 50-90 degrees. This liquid then transfers the heat absorbed to a water storage tank. These solar thermal systems are typically used for the production of domestic hot water. However, they can also be used for heating buildings or through the use of solar cooling systems for summer air conditioning. Relying on Seiad Valley solar installation experts will be the ultimate choice for any service related to solar thermal installation.
Which materials make up a solar thermal system?
The most common solar thermal systems are composed of panels of 2 main types. They are the glazed flat panels and the vacuum panels. Undoubtedly less known are the uncovered collectors and the compact solar accumulators. The solar thermal systems composed of glazed flat panels consist of a metal plate located inside a technically insulated casing, covered front with a glass surface. These panels have a good quality price ratio and a good thermal efficiency for applications such as the production of domestic hot water and the heating of rooms with radiant elements on the floor or for the heating of swimming pools.
The solar thermal systems with vacuum panels are characterized by vacuum glass ducts. Inside which are the pipes that once absorbed the solar radiation and heat the liquid in circulation. Plants with such solar collectors are more complex and expensive to manufacture than those with glazed floors but guarantee a higher yield. Their strong point is the low dispersion coefficient. They are the best in situations of poor insolation and with cold temperatures. They are suitable for those who live in the mountains and when using the solar thermal system and also to integrate the heating of the rooms.
Conclusion: Types of solar thermal systems
Depending on the way in which the circulation of the liquid occurs it is possible to identify 3 different types of solar thermal systems. They are solar thermal systems with natural circulation, forced circulation of solar thermal systems and solar thermal systems depletion. The natural circulation systems are constituted by a solar panel and a storage tank placed on the roof higher than to the panels. The heated fluid can be used directly by the user or it can be limited to circulating between the manifolds and the tank.
