•
Space heating systems
– with underfloor heating the recommended minimum size is
at least half the floor area in solar roofing, although ideally the solar roof will be at least
equal in area to the heated floor area.
•
Pool heating systems
– the recommended size is 60% of the pool area in solar
roofing for outdoor pools, and 85% of the pool area for indoor pools (on the assumption
that indoor pools are used all year.)
•
Combined systems
– the recommended size is generally the larger of any of the
individual parts of the system. E.g. for water and space heating systems, the system is
sized to the space heating requirements.
Design and Layout
Solar roofing may be installed
•
To the extremities of the roof, or
•
As a patch surrounded by a
compatible roofing material, or
•
As a strip between other non
compatible roofing materials.
The visual effect of the solar roofing is a combination of the reflection from the surface, and
the black colour of the absorbers beneath. Overall a uniform medium to light grey is
observed which changes depending on weather conditions.
