Slope and direction of the collector on the roof
To get the best efficiency from the solar collector, it must be mounted at the right direction and slope. Both the slope angle
and azimut angle must be calcuated before and while mounting the collector on the roof.
Slope angle
α
Slope angle α is the angle between the collector and horizontal (x) axis . The absorber used in the collector can get the
most efficient energy when it is mounted absolutely vertically to the Sun’s rays. The angle of the Sun’s rays varies subject
to hourly and seasonal changes. Hence the collectors must be directioned with the correct angle and slope. It is advised
that the angles between 30 and 45 degrees are the most ideal angles to mount the collector.
Azimut angle
Azimut angle means the deflection of the collector axis from south direction. So the angle of the collectors direction to the
south is zero ( 0 ). The axis of the collector should be positioned as close as possible to the south. This is because the
Sun
’s rays are at their peak at noon. The deviation up to 45 degrees to the south can be accepted.
