Abstract: Fire protection systems for a rooftop solar panel installation with solar panels. The fire protection system has a group of water spray nozzles with a metric K-factor of 20 or less to discharge firefighting fluid to a coverage area of the rooftop solar panel installation, a fluid pipe system connecting the group of water spray nozzles to a fluid supply for providing firefighting fluid, a fire hazard detection system with at least one fire hazard detector configured to monitor the coverage area, and at least one detection control unit to generate an alarm signal upon detection of a fire hazard within the coverage area, a valve unit configured to control passage of the firefighting fluid from the fluid supply, wherein the coverage area is at least 500 m2, and the group of water spray nozzles is configured to discharge the firefighting fluid received from the fluid supply to the coverage area with a normalized fluid application rate of 15 mm/m2/min or less.
