How does it Work?
Put simply the solar thermal systems absorb
the suns energy turning it into hot water for
homes.
However it is slightly more complex.
In a standard system, as shown above, the solar
collectors that are mounted onto the roofs of
house or in arrays absorb solar energy from
the sun, they work best when they are tilted
at angles of approximately 30°. The collectors
have specialized solar fluid (Propylene Glycol)
in them, located inside risers, which heats
up from the absorbed solar energy, when this
fluid reaches its optimum temperature it is
pumped from the risers within the collector
into the twin coil solar cylinder, or water
tank, where in conjunction with a household
boiler it heats the water for general house
hold use. The solar fluid is then pumped back
up to the collector to reheat. The whole system
is automatically run by a controller. In summer
weather the boiler does not need to be active
as the solar collector can absorb enough daylight
to heat the water by itself. The solar collector
does not require sunlight, just daylight.
