6.1.1 Mounting
location
The collectors must be installed in a location such that they are not
shaded for 6 hours per day on average over the course of a year.
Evaluating the site for optimal sun exposure is recommended.
6.2
Determining array size
Once the number of collectors in the array is known, you need to
determine if the collectors should be connected into one or more
sub-arrays. If there are more than 10 collectors in the array, at least
2 sub-arrays are needed since the maximum for one array is 10.
Generally it is a good idea to have an equal number of collectors
in each sub-array along with a reverse-return pipe confi guration
to ensure adequate and even fl ow through each sub-array. If it is
not possible to make the arrays even, then balancing valves must
be installed on the supply to each sub-array to ensure the proper
fl ow rates.
6.3
Determining mounting hardware quantity
To determine the number of mounting hardware assemblies in each
sub-array, add 1 to the number of collectors. For example: in a
sub-array with 2 collectors, use 3 mounting hardware assemblies
for proper installation.

Mounting hardware spacing
6.4.1 Tilt mount racking
Finding the on center distance between mounting points
Consult the table below for the rafters that will need to be secured
to. This is a minimum specifi cation. It may be possible or necessary
to add more mounting racks per array if needed to spread out the
roof load.
