Where Tichelmann hydraulic loop balancing is not feasible or the panel strings are not homogeneous, different
number of panels per string and/or panels laid in different directions (portrait / landscape), the installation of
balancing valves is recommended. The sizing of the balancing valves depends on the number of panels per string and
the recommended nominal flow rate, see chapter

.
Provide for the installation of bypass / isolation valves in parallel with automatic
balancing valves for commissioning filling (higher flow rate). With manual
balancing valves, fully open the balancing valves when filling for commissioning.
