Solar Thermal Collector Types

For hot water the type of thermal collector will be defined by the final water temperature.

Solar thermal collector types. An evacuated solar system is the most efficient and a common means of solar thermal energy generation with a rate of efficiency of 70 per cent. Solar thermal collectors are either non concentrating or concentrating. If you need water at a higher temperature to heat with radiators for example the vacuum tube collectors are more suitable. The collector usually moves throughout the day so that it maintains a high degree of concentration on the absorber.

The radiation from the sun heats a liquid that goes to a hot water tank. This process is facilitated by a hot water solar collector. A solar collector operates on a very simple basis. Types of solar thermal collectors.

Solar thermal power plants use concentrating solar collector systems because they can produce the high temperature heat needed to generate electricity. The evacuated tube solar thermal system is one of the most popular solar thermal systems in operation. Thermal solar collectors turn the sun s radiation into heat and then transfer that heat to air or water. As an example if the collector generates 3000 kilowatt hours of energy in a year then 2100.

The collector focuses or concentrates solar energy onto an absorber. There are multiple types of solar thermal collectors.
