Key Takeaways

• Ground-mount solar tracking systems can increase energy production by 25% compared to fixed systems.
• They are best suited for areas with ample space and minimal shading.
• Initial costs are higher, but the increased efficiency can lead to faster payback periods.
• Maintenance requirements are higher due to moving parts.
• Nuance Energy’s Osprey PowerRack™ is cost-effective and faster to install thanks to its modular design which doesn’t require heavy machinery.

What Is A Ground-Mount Solar Tracking System

A ground-mount solar tracking system improves the efficiency of solar panels by allowing them to follow the sun’s path throughout the day.

Solar tracking systems adjust the angle of the solar panels in real-time so they are always perpendicular to the sun’s rays. This can be achieved through:

1. Active Solar Trackers: These use motors and sensors to continuously adjust the panel’s position based on sunlight intensity.
2. Passive Solar Trackers: These rely on thermal expansion and contraction to move the panels without motors, though they are less common.

There are two main types of solar trackers:

1. Single-Axis Trackers: They rotate on one axis to track the sun from east to west.
2. Dual-Axis Trackers: They rotate on two axes to allow for adjustments from east to west and up and down to optimize sunlight capture throughout the year.

Pros Of Ground-Mount Solar Tracking System

Ground-mount solar tracking system follows the sun’s trajectory to maximize energy production.

1. Increased Energy Efficiency: By following the sun throughout the day, the panels receive more direct sunlight – especially during early morning and late afternoon – which can boost energy production by 25% compared to fixed systems.
2. Improved ROI: The increased energy yield from a tracking system translates to faster returns on investment. 
3. Adaptability to Varied Terrain: Ground-mount tracking systems are flexible in design and can adapt to different terrains – including uneven or sloped landscapes where optimal solar orientation would be difficult to achieve with a fixed system.
4. Energy Production in Low Light Conditions: These systems can capture sunlight more effectively during periods of low solar angles, such as early mornings or cloudy days to further increase the energy yield.

Cons Of Ground-Mount Solar Tracking System

1. Higher Initial Cost: Ground-mount solar tracking systems are more expensive compared to fixed-tilt systems due to the additional components like motors, sensors, and control systems required for tracking.
2. Increased Maintenance Needs: The mechanical parts in a tracking system, such as motors and gears, are prone to wear and tear, so they will need regular maintenance.
3. Complex Installation Process: The additional moving parts and electronics require specialized knowledge, which increases the installation time.
4. Vulnerability to Weather Conditions: Tracking systems, due to their moving parts and reliance on electronic components, can be more vulnerable to extreme weather conditions. High winds, snow accumulation, and storms can disrupt or damage the tracking system.

Key Considerations Before Using Ground-Mount Solar Tracking System

1. Site Assessment: Evaluate the location for optimal sun exposure and minimal shading from trees or buildings.
2. Cost Considerations: Assess the initial investment, which may be higher due to the complexity of tracking systems.
3. Maintenance Requirements: Be prepared for regular inspections and potential repairs of mechanical components.
4. Local Regulations: Check zoning laws and permitting requirements that may affect installation.
5. Weather Resistance: Consider the system’s durability against extreme weather conditions, such as high winds.
6. Type of Tracking System: Decide between single-axis and dual-axis trackers based on geographic location and energy needs.
7. Aesthetic Impact: Consider how the installation may affect the visual appeal of the property.
8. Integration with Storage Solutions: Evaluate options for combining with battery storage for improved energy management.
