The sides and bottom of the collector are usually covered with insulation to minimize heat losses to other parts of the collector. Solar radiation passes through the transparent glazing material and hits the absorber plate.
As well as in domestic settings, a large number of these collectors can be combined in an array and used to generate electricity in solar thermal power plants. There are many different types of solar collectors, but all of them are constructed with the same basic premise in mind.
Control of Distributed Collector FieldsThe main control loop in a distributed collector solar field like the one of Fig.1.4 aims at driving the temperature of the fluid leaving the collector loops to a desired value, by manipulating its flow. As explained in Sect.1.2.1 the manipulated variable is the command of the
The radiation received at the earth's surface from all parts of the sky's hemisphere (after being subjected to scattering in the atmosphere) is called diffuse radiation. Solar collector is a device that collects solar radiation and transfers this solar energy to the fluid passing in contact with it.
Point focus collectors and similar apparatuses can also be utilized to concentrate solar energy for use with Concentrated photovoltaics. In this case, instead of producing heat, the Sun's energy is converted directly into electricity with high efficiency photovoltaic cells designed specifically to harness concentrated solar energy.
With flat-plate collectors, the absorber is usually protected from the elements by a casing made from coated sheet steel, aluminium or stainless steel and a front cover made from low-ferrous solar safety glass. An anti-reflective (AR) coating on the glass can further reduce reflection. Thermal insulation of the collector casing reduces heat loss.

We know that the sun is the main energy source on earth. So by using this, the production of energy can be done through solar energy harvesting. So life is constant on earth because the sun generates sufficient heat energy for keeping the soil warm, and this energy is in the form of electromagnetic radiation.
