NEO 2.1 / SUN 211 3. Technical description

3 Technical description

3.1 Operating principle

The short-wave solar radiation (sunlight) striking the solar panel is converted into heat by the selective coating on the absorber. From there it is transferred by heat conduction to the absorber pipe and carried by the heat-transporting fluid to the calorifier. The solar-panel fluid heats the calorifier by means of the energy absorbed from the sun and cools down itself in the process. The cooled heat-transporting fluid then flows back to the solar panel in order to collect more solar energy. An intelligent control system ensures that the circulation system is only active when there is sufficient solar radiation, thus optimising the collection of solar energy.

4 The roof-integral installation set is designed specifically as a

mounting system for the NEO 2.1 flat solar panels and may only be used in accordance with their building regulations approval.

4 The mounting kit is designed for roof coverings in standard

mechanical roman roof tiles for the South of France.

4 The water drainage channels on the membrane should run into

4 The installation should therefore not be flushed or filled when the

collectors are hot (in strong sunshine).

1. Screw the lower fastening lugs onto the bottom batten.

2. Position the collectors. The fastening lugs must be fitted into the

holding groove.

3. Postion the upper fastening lugs in the holding groove on the

collectors and screw them onto the batten.

The solar panels should only be installed shortly before the solarheating system is to be commissioned. This will minimise the time that the solar panels are exposed to heat while not filled with heattransporting fluid.
