While solar energy is most often associated
with the production of electricity, heating
is also a major platform. While heating
isnít particularly difficult, efficiency in
doing so is the key to saving wear and tear
on your system.
A Key Element In Solar
Panels - Efficiency
The sun produces a ton of energy, but
solar panel systems have historically been
very inefficient at converting it. With
improving technology, efficiency has
improved to the point where most panel
systems can easily produce enough energy to
heat water for the home and pools. There are
efficient and inefficient ways to go about
To save wear and tear on your panels, you
need to consider a flow control system.
Older panel systems tend to take a long time
to heat up fluid because water more or less
randomly circulates through the system. This
is very inefficient because the panels are
forced to heat up a much larger pool of
water than you actually need. This results
in wear and tear, not to mention lengthy
waits for hot water.
A control flow system attacks the
efficiency problem by reducing the amount of
water that must be heated. Most are designed
to work on temperature differential
strategies. They work by using two sensors.
The first is located close the panels being
used to heat the water or liquid substitute.
The second is located on or close to the
liquid return valve into the panel system.
Put in practical terms, one sensor measures
the temperature of liquid set to leave the
panel while the other measures the
temperature of liquid coming into the panel.
Flow systems work by waiting for the
liquid to rise to a temperature determined
by you. Once the liquid meets the
temperature, the system turns on the
circulation pump and moves the liquid to the
desired location. Once the return valve
sensor notes the temperature of the
returning water is within a particular range
of the liquid in the panel system, the pump
is shut off. This process allows for faster
heating times, more efficiency and less
Solar solutions are coming to the front
of the energy debate for many residential
energy needs. Countries like Germany are
making huge investments in solar platforms
and technologies. Solar can be a
cost-effective solution for you as well.
Just keep in mind that flow systems are a
must if you are pursuing solar water
