Solar Thermal Systems

A solar thermal system includes solar collectors, one or more solar tanks and individual systems, such as the solar station with its circulator and controller and sometimes the plant for hot water.

Collectors must be high-performance, either are flat with a selective coating on their surfaces, or consisting of vacuum tubes where the collectors' surface is in vacuum for insulation purposes.

The capacity of the solar tank, according to the model we choose, reaches up to 2.000 lt for domestic applications. Domestic hot water (DHW) is usually manufactured with a direct production station when the demand is high via an external exchanger and the corresponding circulators.

In addition, a complete installation must be accompanied by a heating system that will cover the heat demand when the stored energy of the tank is not enough. The condensing boilers with oil or gas or alternatively the use of an air /or water heat pump are the ideally for solar-assisted heating systems are considered.

THE MAIN PARTS OF A SOLAR THERMAL SYSTEM

Solar Collector

Solar Collector

The main role in the process of solar energy acquisition belongs to the solar collectors. They bind solar radiation and convert it into valuable heat. In place of the hose, the collector has an aluminum absorbent material. This binds the sun, heats and transfers the heat to the water passing through the absorbent material. The special coating and the very efficient insulation ensure that as little solar heat as possible is lost. So simple and so effective! The solar collector energy efficiency is usually over 60%. Exceptional insulations ensure low heat losses.

Solar Stations

Solar Stations

The solar station is the "heart" of the solar thermal system, since it is responsible for the proper operation and synchronization of all the individual components.

A solar station consists of the solar controller, the solar pump, a safety valve, manometer and thermometer, as well as non-return valves.

The operation of the solar station lies in the central control of the solar thermal system: Through sensors placed on the solar panels and the solar boiler, the solar controller gives the appropriate commands for the circulation or not of the water in the system. At the same time, the system's operation is recorded on a memory card for better parameterization and immediate monitoring of system performance.
