connecting the collectors to one another
The diagram below is an example of how the collectors can be connected to one another. However, the actual connection may
be different depending on structural conditions. A maximum of 6 collectors may be connected in a series. If a collector panel is
made up of more than 6 collectors, the panel must be connected several times in parallel.
mass flow rate
To ensure the performance of the collector, a specific flow rate of 30 l/m
