Passive Solar Panel Trackers

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.

Passive solar panel trackers.

The sun s heat moves liquid from side to side. 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. 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 allowing gravity to turn the track rack and follow the sun.

Notably speaking solar panel arrays using a passive tracking system receive an increased efficiency rate of approximately 20 more than standard. Mounting your solar panel array is a crucial part of your solar system. This action allows gravity alone to turn the. This imbalance causes the panels to tilt towards the direction of the sun s rays.

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. We are not currently making any passive trackers but do have powered trackers available. Passive solar tracker for photovoltaic modules. Mother s dennis burkholder develops a 34 49 solar tracker that works better than some 200 units we ve seen.

When the liquid evaporates the tilt system becomes imbalanced. The racking must meet local building code requirements and be strong and durable enough to withstand the wind snow and whatever else mother nature throws at it for decades. Track rack passive solar trackers are cost effective reliable single axis trackers that use no external power to target the sun. Passive solar trackers passive trackers contain a liquid with a low boiling point that will evaporate when exposed to solar radiation.

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. 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. During partly cloudy conditions the tracker fixes on the brightest area of the sky capturing the maximum amount of sunlight available.
