Passive Solar Panel Trackers

Mother s dennis burkholder develops a 34 49 solar tracker that works better than some 200 units we ve seen.

Passive solar panel trackers.

This action allows gravity alone to turn the. Normal fixed mounted racking for solar power arrays are only absorbing a peak efficiency at certain times of the day depending on roof angles and facing solar insolation map zones and system design. Make a simple low cost solar tracker see the image gallery for the diagrams of the. The sun s heat moves liquid from side to side allowing gravity to turn the track rack and follow the sun.

Zomeworks passive tracker utr 120 zomeworks utrf 120 passive tracker utrf 120 since 1980 more than 19 000 zomeworks single axis trackers have been installed in different climates on nearly every continent in the world. When the liquid evaporates the tilt system becomes imbalanced. Passive solar trackers passive trackers contain a liquid with a low boiling point that will evaporate when exposed to solar radiation. More info on solar panel mounts.

Active trackers such as wattsun track the sun from east to west using electronic sensors and motor or actuator drives. The sun s heat moves liquid from side to side. Track rack passive solar trackers are cost effective reliable single axis trackers that use no external power to target the sun. Notably speaking solar panel arrays using a passive tracking system receive an increased efficiency rate of approximately 20 more than standard.

As this is a non precision orientation it is unsuitable for certain types of concentrating photovoltaic collectors but works fine for common pv panel types. During partly cloudy conditions the tracker fixes on the brightest area of the sky capturing the maximum amount of sunlight available. We are not currently making any passive trackers but do have powered trackers available. The most common passive trackers use a low boiling point compressed gas fluid that is driven to one side or the other by solar heat creating gas pressure to cause the tracker to move in response to an imbalance.

Passive trackers such as zomeworks uses no motors no gears and no controls that can fail. Zomeworks track racks increase electrical output of photovoltaic modules by 25 or more compared to modules on fixed mounts. Since 1980 more than 19 000 zomeworks single axis trackers have been installed in different. Mounting your solar panel array is a crucial part of your solar system.
