Collector description

REGULUS

 Flat Solar Collectors are designed for solar 

domestic hot water heating (DHW), backup- and pool 
heating with solar energy. Solar radiation penetrates the 
glass and is intercepted by an ef

fi

 cient absorption layer 

applied on an all aluminum absorber. The heat is then 
transferred into heat transfer 

fl

 uid. The absorber is sea-

led in a compact frame with high quality thermal insulati-
on. The collectors are designed for year round operation, 
that’s why they work in a separate primary circuit 

fi

 lled 

with antifreeze heat carrier.

 The collectors are 

not intended

 for direct wa-

ter heating. If different heat transfer 

fl

 uid is used 

than speci

fi

 ed by the manufacturer, irreversible 

damage to the collector may be done.

Transport, handling and storing

Collectors shall be transported in their original packing, 
in upright position (standing on their shorter side) or lying 
horizontal with glass upwards, stack of max. 14 pieces 
on a pallet.
During handling the collector glass shall be always 
facing upwards.
Please check the condition of the collector upon recepti-
on from your supplier or forwarder. Later claimed mecha-
nical damage (frame, glass, connection) will be refused.
When stored, the collector shall not be exposed to rain 
and its absorber exposed to solar radiation.

General instructions for installation

The installation must be done by a trained worker or a 
specialized company. 
During installation and before commissioning, it is 
necessary to cover collectors in order to avoid overhea-
ting and possible burn injury to the installer. 
Prior to installation, conditions set by the roo

fi

 ng manu-

facturer and the max. permissible roof load shall be 
checked.  
Mounting method for solar collectors shall always re-
spect local conditions, i.e. roof inclination and weather 
in

fl

 uence on the overall load on the collector. Kindly con-

sult the fastening method with a structural statics expert.  

During installation the collectors and accessories shall 
be handled carefully. Defects caused by improper hand-
ling or DIY installation are not cover by warranty. 
Generally valid rules and standards for occupational 
safety shall be respected during installation. This con-
cerns mainly technicians walking on a roof and the secu-
ring the area against objects falling down from a roof.
Only REGULUS mount elements may be used. Other 
fastening elements may be used only with a written 
approval from REGULUS company. 
Collectors shall not be exposed to solar radiation un-
til commissioned. The absorption surface may get 
damaged.
Collectors shall be installed and operated in compliance 
with this Manual and with respective generally valid rules 
and norms.

Collector placing

The collector must be placed outdoors. The glass 
absorption surface should be orientated to South, with 
deviations not over 45° (Southwest or Southeast). For a 
year round operation the right inclination angle is 40°-
50°, for summer operation smaller inclination is better 
(30°).
Collectors are installed according to marking.

The collectors shall be installed at an angle 
between 15° and 75°.

On inclined roofs it is recommended to install 

solar collectors as close to the roof ridge as possible. 
Should this solution be impossible, then protections 
against snow slide shall be installed above the collec-
tors. 
The numbers of roof anchors shown in the Mount Kits 
for Fitting and Connecting Regulus Solar Collectors are 
designed for the following load:
Max. permissible snow and wind load 

≤

1,8 kN/m

2

Max. permissible wind load - negative pressure 

≤

1,0 kN/m

2

The customer/user shall be informed about this fact prior 
to starting installation of a solar system. If a higher load 
than shown above is expected in the area in question, a 
statics expert shall be consulted and more roof anchors 
designed, or other measures taken that would ensure 
safe collector 

fi

 tting.  Regulus refuses any responsibility 

for damage  caused by wrong design of collector faste-
ning.
