Solar Collectors

The solar collector contains a system of tubes through which a liquid, such as water, can flow. The liquid is heated by the sunlight up to a maximum of 90ºC. Solar collectors are usually installed on roofs. The heater water is stored in a storage tank. Now, when a hot water tap is opened, the cold pipe water flows through the heated storage tank to the tap. If the water is not hot enough, it is further heated by a central heating boiler or a geyser (gas water heater), etc.

Solar collectors are systems that convert sunlight into heat. A solar collector converts approximately 50% of sunlight into heat annually. Some examples of solar collectors:

• Solar water heater
• Tower system
• Parabolic trough
• Parabolic dish
• Solar chimney
