Is Electromagnetic Radiation From Solar Panels Dangerous?
You aren''t likely to receive much EMR from Solar panels because, while the electrons in AC cabling are constantly wriggling back and forth 50 times a second and creating EMR at a frequency of 50 hertz, DC current doesn''t do this and instead forms a static electric field at 0 Hertz and so should produce very little EMR.
