Facts about Solar Collector

Facts about Solar Collector
The most basic and most common type of solar collector is the flat plate solar collector. At the heart of this collector you will find a sheet of thermally conductive dark material (usually metal) which absorbs as much sunlight as possible. Directly below this sheet a series of water conduits is found; the heat collected by the absorber is absorbed into the water and subsequently carried away by water flow. The collector is housed in an insulating box, with a glass plate on top to further insulate and heat the system. Due to their flexibility, relatively low costs and ease of installation, flat-plate collectors are often used in solar water heating systems.
Evacuated tube collectors consist of a parallel row of evacuated glass tubes. Within each tube, another glass tube is placed, which is covered in a strongly absorbing material. Since the evacuated space blocks both convection and conduction, the absorbed heat has little means of escape. The temperature within the tube itself can therefore reach extreme values, with temperatures of 170 °F to 350 °F commonly achieved. An inherent advantage of the evacuated tubes, is that their cylindrical form means that the collector is always perpendicular the sun. A disadvantage to this system is that sunlight shining in between the tube sis not captured. This can be partly countered by adding a reflective film to the back of the collector. Another disadvantage is cost: evacuated tube collectors are approximately twice as expensive as their flat-plate counterparts.
A solar collector is a device which captures as much sunlight as possible, in order to either redistribute or absorb it into a transport medium. Solar collectors are generally used to generate heat, although in some cases a parabolic dish is used to focus sunlight on a special high-temperature solar cell. The heat generated by a solar collector can be directly used to heat another object or can be indirectly used to generate electricity by driving a steam turbine. Solar collectors come in a large variety of shapes, sizes and purposes. Here, we will introduce you to the most commonly used types of solar collectors. These include the solar collectors commonly seen in solar water heaters.
Solar collectors therefore are important devices to capture the required heat in order to distribute it to specific medium in order to produce enough energy that will later produce electricity. Looking for some renewable energy sources is important to solve different problems we are dealing with nowadays with especially to energy consumption.
