What is the recommended distance from which a fire stream should be applied to solar panels?

The recommended distance of 20 feet (6 meters) for applying a fire stream to solar panels is based on safety considerations and the technical characteristics of the panels. At this distance, firefighters can effectively apply water or foam without risking damage to the solar panels or themselves.

This distance allows for effective cooling of the panels, which can become hazardous due to heat buildup during a fire. Solar panels generate heat when exposed to fire, and applying water from too close could cause thermal shock, potentially shattering the panels or creating electrical hazards.

By maintaining a distance of 20 feet, firefighters can still achieve adequate penetration of the water stream to suppress flames and cool surrounding areas while minimizing the risk of thermal damage to the solar panels. This distance also helps maintain a safe operational zone for the firefighting team, protecting them from any potential hazards associated with the panels, including electrical shock if the panels are still energized.
