Solar Tracking System

SOLAR TRACKING

What is solar tracking?

• Tracking the solar panel or module towards the sun.It helps to reduce the incident angle.

Incident angle-Angle between the module and sun is called incident angle

 

if angle of incidence is zero gives peak power

Efficiency -tracking vs mounting

Depend upon the sun traveling tracking is classified into two types they are

Single axis tracking:

This type of tracking is used for track the sun in one direction -East-West

 

• Increase solar yield up to 34%
• Simple, effective design
• Low maintenance
• Lower cost compared to dual axis
• Minimal points of failure

Dual Axis Tracking:
This type of tracking is used for track the sun in bi- direction -East to west and North to South 

• Increases solar yield up to 37%
• Complex design – more motors and sensors
• Higher maintenance
• Higher cost due to additional parts and installation time
• Additional points of failure

Back Tracking:
 array of single or dual axis solar tracker panels can be made more efficient by the use

of

backtracking.To minimise shading and maximise the power so that the maximum amount of solar energy can be harvested
