Life on Earth is possible only thanks to the sun’s rays. But people use only a slight part of its heat. But it is the heat of the sun that is the most environmentally friendly type of energy.
The main sources of heat are now types of fuel. Its combustion, of course, has negative consequences for the ecology. It is the burning of fuel that leads to most environmental problems of our time. The use of the thermal energy of the Sun will be a safe alternative.
The principle of operation of solar collectors is based on the transformation of the energy of sunlight into heat in the adsorber layer, which is applied to the sheets of the solar manifold. This heat is transmitted to the carrier, whether it be antifreeze or water.
The shape and power of collectors differ depending on the requirements that you present to them. Collectors are of two main types: tubular or panel. The panel collector is better suited for seasonal use, while the tubular can provide the house with hot water all year round, and in the winter — heating.
Fuel saving that collectors depends on the climate of the region. On average, you can save 40% of the fuel when using them exclusively for the hot water. If the solar collector helps and heat the house, then the savings reach 80%. The collector is installed, as a rule, on the roof of the house, but can also be mounted on the surface of the wall or is located on an open area in front of the house.
The system of collectors is both simple, where the coolant circulates naturally and equipped with one boiler, and a very complex scheme with several boilers, branching pipes for heating the floors, pool and so on. In addition, the system can be equipped with automatic control.
The acquisition of a solar manifold will require preliminary calculations for the amount of heat you need. The overall need for heating is considered and the part that the sun can provide.
As a rule, the system of solar collectors completely pays for itself within 2-3 years. Especially fast payback at catering enterprises.
