Passive Solar Panel Tracking System

As this is a non precision orientation it is unsuitable for certain types of concentrating photovoltaic collectors but works fine.

Passive solar panel tracking system. 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. However the design of the sun tracker which. During partly cloudy conditions the tracker fixes on the brightest area of the sky capturing the maximum amount of sunlight available. The solar tracker helps to attempt to navigate to the best angle of exposure of light from the sun.

The passive solar tracker is installed facing due to the south and inclined to the horizon. The second mode is the passive solar tracking mode in which solar photovoltaic modules are mounted on a passive solar tracker. The system moves though one rotation per day. A solar tracker is a device onto which solar panels are fitted which tracks the motion of the sun across the sky ensuring that the maximum amount of sunlight strikes the panels throughout the day.

Active trackers such as wattsun track the sun from east to west using electronic sensors and motor or actuator drives. Main focus of this device is to harvest the maximum solar energy. Solar tracking system plays a vital role in the maximum generation of solar energy. This level of accuracy allows solar modules to capture better than 98 of available light.

A typical solar tracking system adjusts the face of the solar panel or reflective surfaces to align with the sun as it moves across the sky. The passive solar tracker can rotate from east to west to follow the apparent daily movement of the sun. Zomeworks track racks are designed to follow the sun within 10 degrees. Solar trackers are rising in popularity but not everyone understands the complete benefits and potential drawbacks of the system.

Tracking can increase a pv array s power production from 10 to 50 percent depending on the season and location. Schenkelberg in reliability characterisation of electrical and electronic systems 2015. Notably speaking solar panel arrays using a passive tracking system receive an increased efficiency rate of approximately 20 more than standard. Tracker alignment can easily be fined tuned with small adjustments to the aluminum shadow plates.

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.
