No, solar systems are a very safe technology and for many years they've been built without any major safety issues. A comprehensive study by the Fraunhofer Institute has shown that solar systems are very safe. In the rare cases, however, where problems occur, the report showed that DC connectors are the major weak point in a system. While this is manageable in string inverter systems, the adoption of Module Level Shutdown with the currently available options has increased the number of connection points by 2-3 times.

High profile cases of solar related fires in the media mention connection points as a major issue and make solar look unsafe in general. We would like to correct that narrative and make sure that solar systems are built with the least amount of connection points possible.
