Solar Panels
The Artel solar panels range includes headers with natural and forced circulation, to produce hot sanitary water and to integrate the heating system.
Functioning & InstallationFunctioning
The solar thermic panel (solar header) it is a device that convert the solar radiation into thermic energy. This energy is utilized to heat the sanitary water for the daily use and to integrate the heating system.
The solar headers are divided in two categories:
Example of flate plate collector – compact system
Example of evacuated tube collector- pumped system
- COMPACT SYSTEMS: these are monoblock systems with closed circuit that base the circulation on the convention. They do not need therefore electrical pumps. The vector liquid (glycol) inside the panels , getting warmer, starts to expand and it floats on the cooler one. The motion upwards keep the heat in contact with the sanitary water inside the tank;
- PUMPED SYSTEMS: in this case the tank is mounted separately (under the roof or in the boiler room) and the circulation of the glycol is supported by an electric pump controller by an electrical board.
The natural and forced circulation headers are divided between:
- FLATE PLATE COLLECTORS: it is composed by a transparent glass that allows the solar radiations to pass in and stops those going out;
- EVACUATED TUBE COLLECTORS: it is composed by glass pipes inside of which a vacuum is created to avoid the heat dispersion. Inside of them it is positioned a copper pipe that absorbes the heat.
Installation
COMPONENTS
The components for the installation of the solar kit are:
- solar panel;
- hot water accumulation tank;
- hydraulic connection.
For the forced circulation systems these additional components are needed:
- electrical connection;
- circulation pump;
- electronic board.
TYPES
The installations types are different depending on the chosen solar system:
- natural circulation: the tank is installed over the header;
- forced circulation: the accumulation tank is installed under the roof or in the boiler room.
Further depending on the position of the manifolds, the installation can be done:
- with structure for sloping roof;
- with structure for plane surface.
