Solar thermal power is an indirect way to produce electricity, as this system produce heat which is transferred to generators to generate electricity. The most important and major product in solar systems is panels, which are composed with collectors and controllers. When we talk about panels then we can consider three types of panels for this purpose. One work on low heat temperature, other on medium whiles the most powerful works with high temperature. All three panels are made of flat plates that are used to absorb heat from sun but at different levels.
The low temperature panel is used mostly to provide heat in swimming pools, the medium temperature absorber panel collects heat and is used for heating water and providing hot air to houses or commercial buildings. The last one works on high temperature, and is huge in size as well. This is used in industries to run generators with help of renewable energy. It is helping industries in reducing electricity cost very easily.
Other famous products:
Although in total solar panel works best as a thermal product, but this is composed of different devices. These devices are not only part of thermal panels but are also used individually as well for many other purposes. Other famous devices include collectors and controllers.
Thermal collectors:
Solar thermal collectors are used to solar radiations in heat energy. To convert radiations into heat a no-toxic fluid is filled in pipes that get heated with the radiations of sun. The heat that is generated by this fluid is collected and stored in different tanks, at different temperatures. When this heat is needed it is transferred from collectors to generator to run it and generate electricity. This electricity is then distributed in different parts of plant to run machines and some other electrical devices.
Thermal controllers:
In solar thermal system these controllers are used for wide range of purposes. They perform different functions including full programmability; display of error messages or alarms; remote display panels; interaction with a backup electric or gas-driven water heater; measurement of the energy produced; sophisticated safety functions; thermostatic and time-clock control of auxiliary heat, hot water circulation loops, or others; interaction with a backup electric or gas-driven water heater; and remote or local data logging.
Hot water solar thermal controllers:
Now thermal controllers are available in digital form. These hot water controllers are used in different industries to read temperature at solar collectors and also temp of heat stored inside the tank. When heat is needed by generator to work, then controller active the pump and collector provide the heat. These are not used on large industries only, but they are not popular to use in medium and small panels or heat storage tanks as well. These controllers come with multiple features and input or output options. You can easily read temperature from its screen in form of digital numbers. In market wide range is been offered by many manufacturers, you can go and search of your required product easily.
Solar thermal products application:
Solar thermal products are widely used in homes, hospitals, hotels, process industries and at different effluent treatment plants. It shows that how these products are working efficiently at small, medium and large scale. Solar thermal flat plates, evacuated tubes and panels are among most widely used products in all these areas. For personal use we prefer them as well, like while cooking, for hot water, warmth in winters and other similar things. At industries they service need of producing, checking and controlling electricity. Through renewable solar energy, thermal products give us huge benefits.
