The operator of the San Luis Solar Ranch, Iberdrola Renewables, will have a station on site to monitor wind speed and weather. The panels are mounted on trackers, which have motors to position the panels to face the sun directly. When the wind reaches a certain speed, the trackers are designed to turn into a safe, horizontal position but the station operator needs to monitor weather as well. In particular, the main safety concern is lighting and heavy storms. The on-site operators will also be aided by Iberdrola's national control center, which monitors weather nationally and can also see how equipment is functionally remotely.
