MULTIPLE FIELDS
14
If the individual solar fields are exposed to different levels of solar irradiation due to roof angle,
orientation, location or shading, seperate sensors should be used for each field. The fields
should then be treated separately and wired back in to the controller.
The sensor should be placed on the return leg from each field, and one sensor per field.
SCHEMATICS OF COLLECTOR sensor location in multiple fields (fig 4).
When two or more fields are used with potentially different solar irradiation exposure, a pump
is required for each field as well as seperate sensor. The standard SOLARflo control unit
system can manage two solar fields.
It is possible to control two solar fields with two sensors and one pump, but this would require
the introduction of a switching valve.
