Dan:
Electromagnetic fields are only caused by alternating current. Solar
PV generates direct current, which has a functional frequency of 0.
DC voltages have electric fields. DC current has magnetic
fields. But these are not electromagnetic fields.
If anyone has a big concern with any kind of electromagnetic field
then the first thing they need to do is not use a cell phone, which,
during phone call, emits large fields located right at their
head. If they use a cell phone then they are not serious in any
concern about an electromagnetic field.
