Solar collectors

What are solar collectors?

Solar collectors are devices that collect and convert solar energy into heat. This process, followed by the transfer of heat to the coolant, takes place thanks to a special coating capable of absorbing solar energy - the "absorber".

The use of solar collectors or solar systems for:

Heating water for the needs of hot water supply in administrative, domestic and industrial buildings
Water heating in swimming pools
Support of the heating system

Parameters of solar collectors

Before buying a solar collector, carefully study all available information or contact our specialists. The choice and price of a solar collector depends on the tasks at hand, and for each specific case, one or the other option is possible.

Main characteristics of solar collectors

Aperture area. An important parameter on which the collector's performance depends.
The area of the solar collector. Must be considered when choosing an installation site.
The diameter of the condenser. The larger the diameter of the condenser, the better the heat transfer and efficiency of the collector.
The value of optical efficiency and heat loss coefficient. The higher these indicators are, the more efficient the solar system is.

Types of solar collectors

Flat-plate solar collectors consist of a body, an absorber, a copper heat exchanger and thermal insulation. The design features of flat-plate collectors make it possible to prevent overheating of the system by discharging excess heat at night. Vacuum solar collectors are devices in which the conversion of solar energy into heat occurs through special vacuum tubes. Vacuum is an ideal insulator that minimizes heat loss, even in frosty weather. The simplest and most affordable option is seasonal solar collectors. Such devices have a simple design and consist of a frame, an accumulator tank, an expansion tank, and vacuum tubes. They are used only in the warm season, as ordinary water circulates through the heat exchanger, which freezes at sub-zero temperatures. An all-season solar collector is ideal for year-round hot water supply or heating system support. The cost of this system is higher than the seasonal one. Such a system requires additional equipment: a pumping group, an expansion tank, a boiler, and a controller.

Advantages of solar collectors

Cost-effectiveness. By installing solar collectors, you can reduce the cost of hot water and heating.
Environmental friendliness. Solar collectors are safe for the environment.
Durability. The service life is quite high - 15 years or more.
Scope of application. Solar collectors are especially in demand for homes, cottages, hotels and recreation centers.

Benefits of cooperation with Reneco
