Does the panel have a right way up?
The solar air collector panel can be mounted vertically, like a door, or horizontally. The position is solely determined by what looks nicest and the limitations of the building itself.
What is the optimal position for the system?
The system should face as close to due south as possible and have as little shade, from trees or other buildings, as possible.
Is it best to mount the system on a wall or a roof?
In theory, it is best to mount the system on a wall because the sun goes down at 21 degrees centigrade to the horizon (at our latitude) in the winter.
If you mount the panel on the roof, it must be tilted to 50 - 60 degrees centigrade in order to catch the winter sun. The pitch also ensures that dirt does not collect on the surface of the panel and snow does not lie on the light-permeable surface.
Lastly, the pitch is required to ensure that the solar air collector panel can release heat when the system is switched off, e.g. on a warm summer day.
Can I change my mind about installation on a wall or roof?
Yes, we can always send our roof set on afterwards. All models are delivered with brackets for the wall.
What would happen if the upper section of the SolarVenti was in the shade?
If, for example, you mount an SV14 in a vertical position on the wall of a house, and a large overhang prevents the sun from reaching the upper third of the panel, this will still be alright. The solar cell is in the bottom/lower half of a vertical panel. The shade from the overhang will result in a slightly smaller amount of heat from the solar air collector in the summer, when the sun is high in the sky. However, in the winter, when heat is really needed, the sun will be low and the SV14 panel will not be in the shade.
If you mount an SV7 high up on the wall, under the overhang, this will cause problems. The solar air collector will probably remain switched off most of the time. The solar cell is in the middle of the SV7 panel and if it is mounted high up under a large overhang the cell will be in the shade for too long. The problem can be solved by mounting the SV7 a little further down the wall.
n general, shorter pipes give a better utilization of heat.
If the piping must be longer than the lead-in through the wall, you should use smooth pipes in order to reduce resistance/pressure loss.
In the case of the SV3, 1 to 2 meters of smooth piping is the standard length. In the case of the SV7 and SV14, 1 to 4 meters of smooth piping is the standard length (straight piece). In the case of the SV20, 1 to 5 meters of smooth piping is the standard length. In the case of the SV30, 1 to 5 meters of smooth piping is the standard length. If you need longer piping than the above, of if you need to run a pipe downwards into a cellar for example, you will usually have to install an extra fan.
Can you mount a on/off switch, a regulator and a thermostat on the same system?
Yes, SV Regulator Unit works as a thermostat, a on/off switch and a regulator.
How difficult is it to mount a SolarVenti and how long does it take?
It is fairly simple to install a SolarVenti and anyone who is a little talented in the use of ordinary tools will be able to install a system.
The SV3 takes about 1 hour to mount on a wall. The SV7 takes about 2 hours to mount and the SV14 about 3 hours. The roof model takes about twice as long in each case.
