SolarVenti Ltd. has 22 years of
experience in the development,
production and professional servicing of
solar air collectors. Today, we are
market leaders, with almost 25,000
SolarVenti systems operating with
satisfied customers in large parts of
the world. |
|
Today, SolarVenti’s solar air collectors
are all using our own patent, which is
now valid in most of the world. This
gives SolarVenti models many distinct
advantages.

About
the patent and construction
SolarVenti’s patented technology is –
simply explained – a particular intake
of fresh air to the panel through many
hundreds of small holes on the backside
of the panel. The intake is important
for the construction overall.
The particular intake is, among other
things, important for the high
efficiency and the operational security
of the systems.
The very large filter, which is
stretched out across the whole inside of
the particular intake back panel of the
SolarVenti means that the systems are
always kept clean and maintenance-free,
also in the long term.

ventilator can never be damaged from
extraordinarily high panel temperatures.
The self-cooling will always function,
independent of a power supply.
Contrary to competing systems with an
extra cooling ventilator – which can
break and cause heat damage to the solar
cell and ventilator – it would seem
useful and simple to let an extra
ventilator cool the inside of the solar
collector, and at the same time let it
draw warm air out of the house and
through the panel when sun and summer is
at their warmest.
But that is not a good idea. Sending
’used air’ out from the inside through a
solar air collector panel will in the
short or long run cause deposits inside
the panel, which will then need to be
removed, dismantled and cleaned. |

100 %
silent
self cooling
Cooling/self-cooling through a panel
with an extra ventilator on competing
products furthermore does not allow the
user to be rid of the sound of the
ventilator on very hot days. Here, the
extra cooling ventilator on the inside
of the panel makes it impossible to set
the system to ‘silent off’.
At the same time, the cooling ventilator
inside the panel uses the power from the
solar cell, which instead could have
been better used to cool the house with
a separate ventilator, mounted on the
shadow side of the building.

Maintenance-free filter
The filter in a SolarVenti is huge and
takes up the whole surface of the back
panel. It is maintenance-free and will
under normal circumstances never get
blocked.
This means that the user will
avoid problems of non-cooling of the
solar cell and ventilator inside the
panel, caused by a blocked filter, which
then causes a weakened flow and
performance of the panel.

Small
panel – big performance
The position of the solar cell inside
the panel means that - combined with an
optimized internal air flow and a
specifically developed and tuned SV
regulator unit – SolarVenti systems have
a particularly high output per visible
surface area on the solar collector
panel.
In other words: smaller solar air
collector panel with a bigger effect.
Lowest
possible panel thickness
Air intake through many small holes on
the whole surface of the back panel
creates a particular ’cushion’ which
allows SolarVenti to avoid isolation of
the back plate on the panel.
And thus –
without loss of performance – has
decreased the total thickness of the
panel down to 5.5 centimeters for the
models SV2, SV3, SV7 and SV14. |
|
 |
Maximal use of heat from wall to roof
|
 |
|
Since the SolarVenti ’breathes’ into the
filter through the many hundreds of
holes distributed across the aluminum
back plate of the panel, the intake has
no ‘vacuum effect’. The air is drawn in
quietly through a large surface towards
the small holes, and therefore only
draws very little dust into the panel.
The quiet air stream towards the many
intake holes in the panel further means
that heat from underlying wall- and
roof-surfaces are drawn in to a large
extent and are used inside the solar
panel.

An SV
Regulator Unit optimized for solar cells
|
SolarVenti's internally developed SV
Regulator Unit improves the performance
of the solar cell further by approx.
15-20% because the SV regulator is
specifically developed for 12V solar
cell operation.
The small computer of the regulator will
– in relation to the energy of the
actual installation – continually maintain
an optimal work tension inside the
power-producing solar cell.
This
electronic regulation of the way that
the solar cell works causes a marked
improvement of the ventilators’
performance, and therefore of the total
performance of the system.

SolarVenti has experience with almost
25,000 systems in the field – both in
countries as far north as Greenland and
Lapland and, at the other end, Southern
Europe and Australia with the toughest
sun conditions.
We know that our systems
hold up. And we know that they hold up
for a long time. Most of our systems
produced and mounted back in 1986 are
still running without problems.
Our well-extended net of distributors
ensures that SolarVenti owners always
have access to qualified help and
service.
