With increasing pressure from both global energy transition and food security, land resources are becoming more limited. Traditional solar farms and agricultural production often compete for land use.

Agrivoltaics offers a practical solution by combining solar power generation with agricultural production on the same land. By installing solar panels above farmland, this system enables dual land use—generating clean energy while supporting crop growth.

However, agrivoltaic systems differ fundamentally from conventional ground-mounted solar projects. The key challenge lies in achieving the optimal balance between power generation efficiency and crop light availability.

In this balance, the mounting system plays a critical role. It is not just a structural support—it acts as a light management system that directly influences crop growth conditions.

What Is an Agrivoltaic Mounting System?

System Components

A complete agrivoltaic system includes:

• Solar panels – generate electricity and provide shading
• Mounting structure – determines height, tilt, and spacing
• Crop cultivation area – located beneath and between panels

Key Differences from Traditional Solar Farms

Role of Mounting Systems

The mounting system determines:

• Light intensity reaching crops
• Light distribution and uniformity
• Accessibility for agricultural machinery

It is essentially a tool for controlling the ground light environment.

Crop Light Requirements: The Starting Point

Crop Categories by Light Demand

• Full-sun crops (>80% sunlight)
  Wheat, corn, rice, cotton, grapes
• Partial-shade crops (50–80%)
  Soybeans, potatoes, tea
• Shade-tolerant crops (<50%)
  Ginger, mushrooms, leafy vegetables

Impact of Light on Crops

• Yield directly depends on photosynthesis
• Moderate shading may improve quality (e.g., tea)
• Light intensity affects growth cycles

Design must always be crop-oriented to avoid reduced agricultural output.

Key Mounting Design Parameters

1. Panel Coverage Ratio

• Determines overall shading level
• Typical strategies:
  • Full-sun crops: 30–50%
  • Shade-tolerant crops: 60–80%

2. Tilt Angle

• Affects both energy yield and shadow movement
• Larger tilt → longer shadows
• Optimization depends on latitude and season

3. Row Spacing

• Balances light penetration and land use
• Recommended: 4–6 meters for machinery access

4. Mounting Height

• Critical for light distribution and farm operations
• Typical recommendations:
  • Manual farming: 2–2.5 m
  • Small machinery: 2.5–3.5 m
  • Large machinery: 3.5–5 m

Types of Agrivoltaic Mounting Systems

1. Fixed Elevated Structures

• Simple and stable
• Lower cost
• Suitable for large-scale projects

2. Adjustable Tilt Systems

• Seasonal angle adjustment
• Improves both yield and crop conditions

3. Solar Tracking Systems

• Tracks sun position dynamically
• 20–40% higher energy output
• More complex and higher cost

Balancing Energy and Agricultural Benefits

Successful agrivoltaic projects optimize total system value, including:

• Energy revenue
• Crop yield and quality
• Water savings and microclimate benefits
• Government incentives

Project Priorities

• Energy-focused → higher coverage, optimized tilt
• Agriculture-focused → wider spacing, higher structures
• Balanced → moderate design with optimization

Site-Specific Design Considerations

• Solar radiation and climate
• Land topography (flat vs. sloped)
• Crop types and farming methods
• Irrigation systems and access roads

Common Design Challenges

• Uneven shading → uneven crop growth
• Insufficient height → limits machinery
• Ignoring seasonal sun changes
• Lack of coordination between agriculture and PV design

Engineering Optimization Methods

• Use simulation tools (PVsyst, SketchUp, Helios 3D)
• Apply modular design for flexibility
• Customize solutions based on crops
• Integrate agricultural and engineering expertise early

Designing for Long-Term Agrivoltaic Success

The essence of agrivoltaics lies in balance—not compromise, but optimization.

A well-designed mounting system can:

• Maximize clean energy production
• Maintain or improve crop performance
• Enhance overall project profitability

As demand for efficient land use grows, agrivoltaics will play a key role in sustainable development.
