Dwellings - Apartment blocks
The most practical installation method in apartment blocks is when solar
heating panels pre-heat one or two central calorifiers which then feed
all the apartments. The alternative option of each apartment having
its own cylinder (with flow and return pipe work going to the solar
panels) can prove to be impractical.
Dwellings - Houses
When the project involves houses with their own roofs then the most
practical solution is to have each property with its own cylinder with
the corresponding number of solar heating panels. The size of the cylinder
will depend on its type (vented or unvented) and the occupancy of the
property. The number of commercial solar heating panels depends on the
capacity of the hot water cylinder, orientation of the roof and length
of the solar pipe run.
The high running costs of large swimming pools (both indoor and outdoor)
can be vastly reduced by using commercial solar panels. Typically unglazed
collectors are used for outdoor pools which only tend to be used in
the summer months and the more efficient vacuum solar panels are used
for indoor pools which need to be heated year round.
commercial solar heating system is sized to compensate for the heat
loss of the pool. The heat loss is directly related to the surface area
of the pool and whether it is covered or not. Typically the solar heating
panels need to be 30%-50% of the pool surface area.
commercial solar projects
For most commercial solar heating projects (eg offices, factories, schools,
hotels etc) solar heating can be used effectively to contribute towards
the hot water product of the facility saving money and reducing emissions.
The number of panels required depends on size of calorifier, length
of pipe run and the orientation of the solar panels.
Panels is one of the highest performing panels on the markets yet the
reason that it's specified for so many commercial solar heating projects
is due to robustness and reliability and the strength of the manufacturing
Due to the borosilicate glass construction and the lack of
metal to glass seals the solar collector can withstand a stagnation
temperature of up to 295°C. This is particularly important in commercial
solar heating projects where often the panels are installed in large
array and any problem (such as a power cut) can cause a rapid increase
in temperature in the system.
