Are electromagnetic fields from solar farms harmful to human health?

Electromagnetic fields from solar farms are far too weak to harm human health and fall well within accepted safety limits for exposure.

Solar equipment emits non-ionizing radiation, meaning it has enough energy to move atoms in a molecule but not enough to remove electrons or damage DNA. Solar farm EMFs are even less energetic than other forms of common non-ionizing radiation such as radio waves, infrared, or visible light. 

Even when standing directly beside the largest-scale equipment, EMF levels measure around 1,050 milligauss (mG), lower than exposure from using an electric can opener (up to 1,500 mG) and well below exposure limits (around 2,000 mG). At distances typical of real-world exposure – 9 feet from a residential inverter or 150 feet from a utility-scale inverter – field strength falls to 0.5 mG or less.

Scientific reviews find no consistent evidence of negative health impacts from EMFs produced by solar farms.
