I found this complete file on electromagnetic or magnetic pollution made by Science & Avenir in May 2002 which gives a good basis (this will change for some paranoid sectarian websites).
Obviously, this dossier was realized long before we talked about air pollution as it is now.
[B] You can make your own measurements with this kind of cheap device: Gaussmeter magnetic field detector

Just a remark to relativize the obscure 10 μT ...
The Earth's magnetic field also makes 50 μT in France
Is it necessary to move away from the Earth? Will we be better off in space?
And it's a little HS, but this field protects us from cosmic rays.
50 µT for the earth, Yes ..... but it is a "continuous" or "static" magnetic field like a permanent magnet and not low frequency. And apparently the difference is huge.
This makes me ruminate, because I work occasionally, and my colleagues full-time, measuring enormous magnetic fields on parts (2-3 second pulses at 50-300Hz can be> 12800 A / m) ..... without protection or safety instructions .... It only makes 160 times the norm ...
In addition, there is an electrician (who should be perfume) who has found it more convenient, for easier maintenance, to turn the metal cowls that protect from magnetic leaks (power part of the machine, transformer etc.). ..). When I asked for the cowlings to be replaced, not sure that they didn't take me for a fool. "You know, it's been like that for years and the cowlings disappeared .... It's okay, it was against the (wooden) partition."

Hi Flytox,
For a big machine, indeed, the good precaution is to cover metal.
That said, in the domestic, I think there is a bit of alarmism ... Even at low frequency (50Hz), the body is very little sensitive to electromagnetic radiation.
People would be better off protecting themselves from the sun, cigarettes or alcohol abuse than from psychotaping the EM emissions of their hairdryers

There is at least one solution: Le Mumétal, to make shields and to guard against these Low Frequency fields.
http://fr.wikipedia.org/wiki/Mu-m%C3%A9tal
http://fr.wikipedia.org/wiki/Mu-m%C3%A9tal
The mu-metal or mumetal or Mu-Metall is an alloy of nickel and iron.
There are several nuances of mumetal depending on the manufacturer. The "French" mumetal is composed of 80% of nickel, 15% of iron, and 5% of molybdenum. The German "Mu-Metall" is composed of 77% of nickel, 15% of iron, 5% of copper and 3% molybdenum.
This material has a very high magnetic permeability which allows it to attract magnetic field lines.
Mumetal takes its name from the symbol μ (ie the letter mu in the Greek alphabet) used to denote magnetic permeability.
The high permeability of mu metal makes it an excellent material to deflect static magnetic fields or low frequency, against which other mitigation methods are very effective.
It is used in the manufacture of magnetic shields for industry, research or high technology.

As a result of this reading and many more besides, I coldly cooled down the installation of PV + inverter at home.
To counter this undesirable pollution (because the house is and must remain a haven of peace)
1) to put a screen in Mumétal roofing to protect from the radiation of the PV
2) cables 4² or 6² connecting the photovoltaic protected by a specific jacket
http://www.flex-a-ray.com/
3) The inverter located in the basement not far from the rooms of life, to create a cowling with a material quoted above by Flytox (Le Mumétal)
4) Abandoning the idea of PV roof at home (it's radical
)
If you have other track.
PS: I have tested with the Gausmeter on an existing installation, at the level of the inverter it carton !!!

??? I still ask myself questions:
The panels emit a weak but continuous magnetic field.
So, it must not be more terrible than a few magnets that trail, or the magnetic contacts of your alarm system
And not all the time, and never when you sleep (well ... at night)
And the magnetic field of one of the drop wires partially cancels that of the other

Mumétal solves some problems but ..... it's "a bit" expensive for a private individual .....

I contacted the Criirem
Good news
I contacted the Criirem (independent research and information center on magnetic radiation) concerning the installation of photovoltaic panels.
The copy of my mail below:

Hello,
The panels themselves are not problematic, it is the inverter must be away.
We recommend a distance of 80cm-1m so avoid putting it on a wall behind which would be a place of rest. The garage is more appropriate.
Happy New Year 2013,
