| As a guide for calculation
purposes, the area of solar panels should equate to 50% of
the pool surface area, more if the pool is in an especially
exposed location. They should be installed in a sunny position
facing south inclined at 15° -30° to the horizontal. In a
typical system the solar panels are linked into the filtration
circuit, making use of the filter pump. Filtered water passes
through the panels ahead of any heater, allowing free solar
energy to be used first with back up heating only cutting
in when a further boost is needed.
For solar panels to achieve optimum efficiency there should
be some form of automatic control to ensure that pool water
only passes through the panels when there is a solar gain
available. The Suncell automatic control system achieves this
with a Differential Temperature Controller (D.T.C) operating
a three port motorized valve. |
