Solar photovoltaic (PV) systems are some of the safest types of ways to generate electricity. Once installed, there are few (if any) moving parts, no need for extracting fossil fuels from the earth, no danger of meltdowns or spills…the array just sits there soaking up the sun. As with any type of electrical system, though, there is always the danger of dealing with high voltage going somewhere it wasn’t intended.

The biggest risk for PV is a ground fault, which under certain circumstances could potentially start a fire. It is, however, extremely rare. A 2010 study by the National Fire Prevention Association found only a handful of incidents over more than 30 years (more…)
