By fixing the modules due south, less water is pumped than a tracking system which orients the modules towards the sun as it arcs across the southern sky. Tracking Mount structures keep the modules at a 90 angle to the sun all day long. This provides more power to the pump over a longer period of the day, which produces 30 to 40 percent more water daily in the summertime.
Trackers offer a great advantage when pumping water.
Our passive single axis trackers are known for their excellent reliability and service life. They take no power from the system as they operate from the heat of the sun striking the frame members, causing freon to move from one cylinder to another. Our trackers come with a 10 year warranty and are highly recommended in all but the most windy locations. High winds can pull the array off the correct sun angle and will negatively affect power production if winds are consistent. Even shadows from a tree limb, tall grass or fence rails can substantially reduce power output.
