Link collector
A possible link can be seen in the attached sketch. Based on the structural characteristics of the
situation, however, may be different in practice. If the collector field consists of more than 6
collectors (vertically aligned) or 4 collectors (arranged horizontally) in the series, it is necessary to
plan appropriate measures to compensate for thermal expansion due to temperature fluctuations
(expansion bends or flexible pipe) or a field to be multiple times in parallel run.

Flow rate
In order to achieve good performance collector,
should be the size of the field around the collector about
25 m² to choose a specific flow rate 30 l / m² h.
