Prior
to you purchase and set up a solar water heating unit, you first need
to take into account your location’s solar supply, and also the most
favorable orientation & tilt of your solar collector. The design and
efficiency of a solar water heating unit relies upon how much sun’s
energy reaches your building location.
Solar
water heaters employ both direct & distributed solar radiation.
Even though you are not living in a climate that is sunny and warm, most
of the time your location still might have sufficient solar supply. If
your building location feature unshaded areas and usually south-faced,
it is a great candidate for solar water heaters. Your local solar system
installer or provider can do solar site investigation.
Both
the orientation & tilt of the collector will have an effect on the
performance of your solar water heating system. Your contractor must
take into account both the aspects while assessing your site’s solar
supply & sizing your system.
Collector Orientation:
Solar
hot water collectors or panels must be geographically oriented to
exploit the amount of regular & seasonal solar power that they get.
Usually, the most favorable orientation for a solar-panel in the
northern geographic region is true south. Nevertheless, latest studies
have established that, relying on your site & collector tilt, your
panel can face about 90ยบ west or east of true south with no significant
decreasing in its performance.
You
will also wish to take into account aspects like roof orientation,
local climate conditions and local landscape features that shade the
panel regularly or seasonally, as these aspects may have an impact on
your collector’s optimum orientation.
Collector Tilt:
These
days, a majority of solar water-heating collectors are ascended flat on
the roof. This’s more visually pleasing compared to rack-mounted
collectors, which stick on the roof at very odd angles. Therefore, most
collectors feature the same tilt as the roof.
Though
the most favorable tilt angle for your solar collector is an angle
equal to your latitude, fitting your collector flat on an angled roof
won’t upshot in a considerable reduction in terms of system performance.
However, you will wish to consider roof angle into account while sizing
your system.
