Select the best possible orientation for the solar collectors (ide-
ally facing south). Avoid positions that are shaded by plants,
trees, buildings or hills, etc. during the day.
In systems in which the summer load is predominant (produc-
tion of domestic hot water) aim the collector from east to west
with a variable inclination from 20° to 60°. The ideal direction
is southwards, with inclination equal to the latitude of the lo-
cation -10°. If the system sustains the greatest thermal load in
the winter (as in systems that combine domestic hot water pro-
duction with central heating), install the collectors facing south
(or south-east or south-west) at an angle greater than 35°. The
ideal orientation is southwards, at an angle equal to the lati-
tude of the location plus 10°.
Remove all gravel and detritus from the surface on which the
system is to be installed.
Do not use flat roof or sloping roof mounting frames to install
any other equipment. They are designed only for use with R
solar water heating systems.
The installation of the solar field changes the pre-existing struc-
ture of the roof. It is necessary to check and possibly adapt all
the roof elements to prevent any seepages or damages caused
by wind and/or snow.

Collectors must be installed at a safety distance from active
parts of electric lines and electric systems as required by the
laws and regulations in force in the country of installation.
In the absence of specific rules, the minimum installation dis-
tance required minus the side movements of conductors due
to the action of the wind and of the lowering in height due to
thermal conditions is as follows:
H
Voltage range H
< 1 kV 3 m
1 ÷ 30 kV 3,5 m
30 ÷ 132 kV 5 m
< 132 kV 7 m

Contact with open, live electrical wires may lead to electro-
cution and may even be fatal.
9
Non-electrical works near live unprotected electric ducts
with which a contact is possible must be carried out in ac-
cordance with laws and regulations in force in the country
of installation.
