Description of product
EASE OF ORDERING
To make life as straight forward as possible, Grant have
introduced a series of individually numbered kits that
meet most installation requirements.
These simply consist of the Sahara collector, a roof
mounting system, expansion vessel, pump station, control
panel, pipe connections and solar fluid - all of which
can be installed in approximately two or three days.
DESIGNING YOUR SYSTEM
Grant Solar Collectors have a total area of 2.34m2. As a
rule of thumb, when sizing a system, you should allow
1.0-1.3m2 of collector area, per person.
Cylinder requirements are 50-60 litres capacity per m2
of collector area.To simplify this, for a 2-Collector
system of 4.68m2, you would require a cylinder of
approximately 200 litres. This would be sufficient for 4
people and satisfy up to 70% of your hot water demand
per annum.
Things to consider:
_ Location of building
_ Orientation of building
_ Angle of Inclination (roof)
_ % of Solar Contribution
_ Hot water requirements
_ Volume of system
_ Shade
_ Collector array in m2
_ Size of cylinder
_ Pipework requirements
