2 Information about the installation
set
2.1
Intended use
The rooftop installation set is designed to hold solar
thermal collectors and their associated tank, which
are installed on flat roofs at an angle of 23°/ 33
o
/ 40°.
Never damage the structure of the building while
installing the solar thermal system.
Conditions of use
Only fit the installation set on roofs with sufficient load
bearing capacity; if necessary, consult a Civil
Engineer / Architect.
The standard installation set is suitable for an
installation height of
not more than 20 m
.
Consult Bosch to fit additional profile rails, which are
not part of the standard delivery, in the case of
greater installation heights (up to 50 m or with wind
speeds in excess of 129 km/h) .
Never use the rooftop or flat roof installation sets to fix
any other objects to the roof. They are designed only
to hold the solar collectors and tank securely.
Observe country-specific standards and
directives when installing and operating
the heating system.
The installation of a solar circuit pump can
be
considered
in
place
of
the
thermosiphon
if,
due
to
static
considerations, the roof is unable to bear
the weight of the tank.
IMPORTANT
:
We
recommend
our
customers not use the water from solar
system directly for drinking purpose.
2.2
LIGHTNING PROTECTION
•
Check regional regulations as to whether a lightning
protection system is required.
•
Lightning protection is normally required for
buildings higher than 20 m,
•
Have a qualified electrician to install the lightning
protection.
•
If a lightning protection system is installed at the
location, check whether the solar thermal system is
also included.
•
Consult a Civil Engineer / Architect for further
information, if necessary on "Recommendations on
Lightening Protection"
2.3 Important Working Conditions
The Solar Water heating system requires minimum
one day to generate the required hot water depending
on the solar radiation.
The system will generate the hot water at an average
temperature of 60
o
C
*
under standards conditions.
There will be overnight drop in temperature of 6 to
8
0
C at an ambient temperature of 22
0
C. Drop in
temperature will be more at lower ambient
temperature.
When hot water is drawn from the system, equal
amount of cold water enters the solar tank thereby
reducing the overall temperature of the water inside
the tank.
Standard Conditions
-
Solar Radiation should be minimum 5.5kW/m
2
/day
-
Inlet water temperature should be minimum 25
o
C
-
System should be installed as per instructions in
shadow free area.
-
No water is drawn from the system during day time
(08:00 to 18:00).
-
Output Temperature measured at the outlet of the
solar tank at 18:00 hrs
-
Performance of the solar thermal system depends
mainly on Solar Radiation, Geographical and
Climatic Conditions apart from the components.
The performance may accordingly vary from one
location to other.
