Solar Tracker by SIKCO Engineering Services Private Limited

Principle of Operation:

• The tracker basically calculates the astronomical position of the sun at any particular point of time at a particular location and controls the actuator accordingly to move the panel to the target angle. The calculation of the next target angle at the next target time is calculated and the tracker accordingly activates the output when the target time has been reached.
• The calculation of the target angle depends upon the sunrise and sunset times for the particular date. The principle lies in that the sun moves from the east horizon from sunrise to the west horizon till sunset for a total of 180 degrees. The unit calculates the target angle according to the following limits:
• If target angle < start angle then target angle = Start angle.
• If target angle > end angle then target angle = End angle.
• This ensures that the panel movement is restricted to the minimum/maximum angle set by the user for that particular structure. The panel will start moving in the morning only when the target angle exceeds the start angle .Similarly, in the evening, when the target angle calculated exceeds the end angle , the panel will remain at the end angle position till sunset. At 10 minutes after sunset, the tracker will move the panel to the horizontal position and retain it till the sunrise the next day when it will bring the panel to the start position.
• Solar tracking system produce 15-25% more power than traditional solar plant.
