Single Axis Solar Trackers
Solar tracking systems can be categorized based on how they move. These systems have a photovoltaic (PV) surface that can be rotated or tilted along axes to achieve the ideal angle for capturing maximum sunlight. When the PV surface adjusts by rotating around one axis, it’s referred to as single-axis tracking. Conversely, when it moves around two axes simultaneously, it’s known as dual-axis tracking.
Types of Single axis Solar Tracker
Here are descriptions of different types of single-axis trackers:
Horizontal Single-Axis Solar Tracker (HSAT): HSAT rotates east to west on a fixed axis parallel to the ground. It’s cost-effective and widely used in PV applications. It requires minimal construction material and is preferred for its horizontal configuration.
Horizontal Tilted Single-Axis Solar Tracker (HTSAT): HTSAT is similar to HSAT but installed with a tilt. They are more complex and expensive, requiring a concrete foundation. They are not considered scalable.
Vertical Single-Axis Solar Tracker (VSAT): VSATs can be mounted in either north/south or east/west orientation, tracking the sun’s up-and-down movement. Common in high-altitude or extreme latitude locations.
Vertical-Tilted Single-Axis Solar Tracker (VTSAT): VTSATs are like HTSATs but with a vertical axis rotation. They yield higher energy production than horizontal trackers but are subject to increased wind loads, demanding a robust foundation with extra concrete and steel.
Benefits of Single Axis Solar Trackers
Here are the advantages of single-axis solar trackers:
- East-West Sun Tracking: Single-axis trackers follow the Sun’s path from east to west.
- Cost-Effective: They are affordable, simple to install, and operate at a low cost.
- Reliability: Single-axis trackers are more reliable compared to dual-axis trackers.
- Longer Lifespan: They have a longer lifespan than dual-axis trackers.
- Budget-Friendly Option: Ideal for companies seeking a cost-effective solution.
- Versatile: Suitable for regions with limited sunlight.
- Higher Efficiency: Single-axis trackers are 32.17% more effective than fixed solar panels.
