Agrivoltaics, often referred to as Agrivoltaic Systems (AVS) or Agri-PV, is the co-location of agricultural activities and solar power infrastructure. Unlike conventional ground-mounted solar plants—which convert fertile topsoil into industrial zones through clear-cutting and soil compaction—agrivoltaics seeks a symbiotic relationship between light, plants, and solar modules.

How Agrivoltaics Works

The fundamental scientific premise rests on light management and microclimate modification:

• Photosynthetic Active Radiation (PAR): Plants do not absorb 100% of the sunlight hitting their leaves. Beyond a certain point—known as the light saturation point—additional solar radiation does not increase photosynthesis; instead, it causes heat stress, excessive transpiration, and photoinhibition. Agrivoltaics uses solar panels to capture this excess light, leaving optimal PAR for crops beneath.

• Microclimate Regulation: The shading created by elevated panels reduces soil evaporation and plant transpiration. This creates a milder, cooler microclimate during peak daylight hours.

• Panel Efficiency Gains: Solar PV modules lose efficiency as their temperature rises. The transpiration from crops beneath the panels releases water vapor, cooling the ambient air around the modules and boosting their solar power generation efficiency by 3% to 10%.

Key System Configurations

1. Stilted / Overhead Frameworks: Solar structures are elevated 2.5 to 4 meters high. This allows tractors, tillers, and farm labor to operate underneath without obstruction.

2. Inter-Row / Vertical Installations: Solar arrays are installed vertically or in wide-spaced rows oriented north-south. Crops grow between the panel rows, receiving full sunlight during parts of the day and partial shading during others.

3. Dynamic / Smart Tracking Agrivoltaics: Automated single-axis or dual-axis trackers tilt panels according to the position of the sun and crop shading needs, optimizing both crop photosynthesis and electricity production throughout the day.
