SOLE S.A. – Solar Collectors – Installation Manual

keeping the solar collectors outdoors with the cover glass facing down on wet
surfaces, in order to prevent entry of humidity or water in the rear of the collector.
Figure 6. Distance needed in order to avoid shadows on collectors.
Once at work, in the event that the installer observes the existence of elements that
can cause shadows on the solar collectors and have not be taken into account in the
design of the system, as protection walls in terraces, fireplaces, outdoor air
conditioning units or other elements, should inform the designer of the project or the
owner of the property in order to revise or amend the calculations made for the
location of the collectors, if necessary.
The system of fixing the support frame of the solar collectors to the building also
must be determined in the design phase of the installation, for example by
conducting benches built on a flat roof. In this case, the thickness and size of the
bench should be sufficient to ensure stability of the whole in case of strong gusts of
wind. In any case, the solution adopted should ensure the solidity and stability of the
setting without compromising the watertight integrity of the deck. To facilitate the
design of the fixing system, figures 7 to 13 show the distances between the support
frames of the solar collectors.
4. Banks of Collectors
The solar collectors can be connected with each other to form banks of up to 6 units
in parallel, connecting the top and bottom of the collectors through the fittings
included in the set.
The dimensions of pipe connections for collector arrays up to 20m² is 22mm.
It is recommended that the connections between the different banks of collectors are
also conducted in parallel. However, the connection of up to two banks of solar
collectors in series is allowed.
In the following figures from 6 to 13 shows the dimensions of the solar collectors from
1 to 6 units and for different angles of inclination. Additionally, there should be
sufficient space around the banks of collectors to perform with comfort the hydraulic
connections.
