Installation instruction
of the flat solar collectors models ES1V2.0, ES1V2.65,
ES2V/2.0 AL, ES2V/2.65
integrated in the slate roof.
3.5 Location of a collector
Potential quantity of the absorbed radiation depends on a proper location of
the absorber in relation to falling sunbeams.
Optimum is a perpendicular position of a collector surface in relation to the
falling solar radiation.
Recommended location of a collector:
inclination angle:
40 – 45
o
for a year-long installation,
approximately 30
o
for installations used in summer,
approximately 60
o
for installations used in winter,
positioning of a collector in the southern direction (or approximate to the
southern direction).
Solar collectors must not be installed at the inclination below 30
o
or
over 75
o
.
It is recommended to install the collectors on the southern roof slope. During
the installation work particular attention should be paid to protect the
collectors from being overturned by strong winds. Permissible snow
and wind load amounts to max. 2,0 kN/m².
Collectors field should be located in such a way that the absorber will
not be shadowed by the adjacent buildings, trees, etc.
In case of a larger number of collector fields it is important that the front row
of the collectors do not shadow the back one.

Required space
ES1V/2,0 and ES2V/2,0 AL for vertical installation
Required about 2400 mm in height and 1800 mm in width for the first
collector and + 1110 mm in width for each consecutive one. In case of
mounting a collector on the inclined roof the minimum distance between
collectors and the roof edge is 1m.
