Agrivoltaics: Across the world, farmers, energy developers, and policymakers face the same challenge: how to meet rising food demands while expanding clean energy to tackle climate change. Traditional solar farms require vast amounts of land. Agriculture also needs large areas — and both demands often collide, especially in densely populated or land-scarce regions.
This is where agrivoltaics steps in.
Agrivoltaics (or agricultural solar) is the practice of using the same land for both farming and solar photovoltaic (PV) energy production. Instead of choosing between crops or solar panels, agrivoltaic systems combine the two, creating a new land-use model known as dual-use land systems.
The idea may sound simple, but its impact is transformative. Agrivoltaics helps:
- Protect crops under rising temperatures
- Improve water efficiency
- Produce clean, affordable power
- Support farmers with new income streams
- Reduce land-use conflicts
- Increase biodiversity and soil health
- Accelerate the shift toward carbon-neutral energy systems
This article offers an in-depth look at agrivoltaics — how it works, real-world benefits, economic potential, system designs, crop suitability, challenges, and strategies to implement dual-use solar successfully.
1. What Exactly Is Agrivoltaics?
Agrivoltaics combines solar PV panels with agricultural activities in a way that both can function efficiently. This includes:
- Growing crops beneath, between, or around raised solar panels
- Grazing sheep, goats, or cattle under solar arrays
- Planting pollinator-friendly vegetation under solar installations
- Using semi-transparent or vertically mounted PV in orchards and vineyards
Unlike conventional solar farms, which often remove farmland from production, agrivoltaics ensures the land remains biologically productive while also generating electricity.
The core idea:
One piece of land → Two outputs
✔ Agricultural products
✔ Renewable energy
This increases the overall value and productivity of the land, offering clear environmental and economic advantages.

2. How Agrivoltaics Works: The Science Behind Dual-Use Systems
Agrivoltaics is effective because of three main interactions between solar panels, plants, and microclimate conditions:
Solar Panels Provide Partial Shade
Solar panels reduce the intensity of direct sunlight on crops. For many plants, this is beneficial because excessive heat and strong sunlight:
- Increase evaporation
- Stress plant tissues
- Reduce yields
The partial shade from panels can help maintain cooler soil temperatures and healthier crop canopies.
Improved Microclimate
Solar panels alter the microclimate by changing:
- Wind patterns
- Soil moisture
- Humidity
- Ground temperature
These changes often create a more stable environment, especially in arid or heat-prone regions, helping plants survive extreme weather.
More Efficient Use of Land
Solar panels generate electricity from a resource (sunlight) that is abundant and free. Combining electricity production with agriculture increases the total productivity of the land, often leading to higher net revenue per hectare compared to farming or solar alone.
3. Key Benefits of Agrivoltaics
Agrivoltaic systems offer numerous advantages for farmers, local communities, and the environment. Here are the most significant benefits:
Improved Water Efficiency
Shading from solar panels reduces:
- Evaporation rates
- Soil moisture loss
- Irrigation needs
Many field studies have shown that crops under agrivoltaic systems require significantly less water, a major advantage in drought-prone regions.
Enhanced Crop Resilience and Stable Yields
Crops grown under partial shade often show:
- Less heat stress
- Reduced sunburn
- Better survival rates during heatwaves
- More consistent yields in hot summers
Shade-tolerant crops may even see higher yields.
Increased Land Productivity
When combining agricultural output with electricity generation, the total productivity per hectare increases dramatically. Even if crop yields drop slightly, the added value of electricity more than compensates.
New Income Streams for Farmers
Agrivoltaics can provide farmers with:
- Lease income from solar developers
- Electricity bill savings
- Profits from selling electricity to the grid
- Reduced irrigation costs
The financial stability from a diversified income is especially important for small and mid-scale farms.
Biodiversity Support
When designed thoughtfully, agrivoltaic installations can host:
- Pollinator habitats
- Native grasslands
- Soil-building vegetation
- Wildlife corridors
This differentiates agrivoltaics from conventional solar farms, which often require extensive land clearing.
Carbon Reduction
Agrivoltaics supports the global shift toward renewable energy without removing farmland, making it a powerful tool for:
- Lowering carbon emissions
- Reducing dependence on fossil fuels
- Supporting climate-smart agriculture
4. Types of Agrivoltaic System Designs
Agrivoltaics isn’t a one-size-fits-all model. Several designs are used depending on crop type, climate, terrain, and farming practices.
Elevated Solar Arrays (High-Mount Systems)
Panels are installed 2 to 5 meters above the ground, allowing:
- Tractors to pass
- Mechanical harvesting
- Livestock grazing
- Crop cultivation beneath the array
High-mount systems work well for diversified farms and commercial crops.
Widely Spaced Rows
Panels are installed in rows with wide gaps (4–8 meters) to allow:
- Sunlight penetration
- Crop rows between solar structures
- Easier machinery access
These systems suit farms growing row crops or practicing strip-cropping.
Single-Axis or Dual-Axis Trackers
Trackers allow panels to move with the sun, reducing excessive shading and improving electrical output.
Benefits:
- Reduced shading during certain hours
- Consistent energy generation
However, trackers cost more and require additional maintenance.
Semi-Transparent and Vertical PV Systems
Used primarily in:
- Greenhouses
- Vineyards
- Orchards
Semi-transparent panels allow filtered sunlight to reach crops, balancing photosynthesis with electricity generation.
Solar Grazing Systems
Panels are installed at moderate heights to allow grazing animals such as:
Solar grazing reduces vegetation management costs and offers:
- Sheep
- Goats
- Cattle
- Shade for livestock
- Cooler microclimates
- Improved grass quality
5. Which Crops and Livestock Work Best?
Good Crop Candidates
Shade-tolerant or partial-shade crops perform best under agrivoltaic systems, including:
- Lettuce
- Spinach
- Kale
- Herbs (mint, coriander, basil)
- Berries (strawberries, blueberries)
- Root crops (carrots, radishes)
- Specialty crops (ginseng, saffron)
These plants thrive under lower light intensity and cooler soil temperatures.
Moderate or Conditional Candidates
Some crops do reasonably well depending on panel height and spacing:
- Tomatoes
- Potatoes
- Peppers
- Beans
- Wheat (in certain climates)
These require careful system design to avoid excessive shading.
Livestock
Livestock is often the easiest dual-use category:
- Sheep are ideal for solar grazing
- Goats are good but require fencing
- Cattle can graze under elevated arrays
- Chickens can forage under small installations
- Livestock benefit from cooler temperatures and improved forage quality.
6. Economic Potential of Agrivoltaics
Agrivoltaics transforms farmland economics by diversifying revenue streams. The profitability depends on several factors:
Revenue Streams
A typical agrivoltaic farm can earn money from:
- Electricity sales to the grid
- Reduced on-farm energy bills
- Crop production under the panels
- Grazing fees or livestock revenue
- Government incentives for clean energy
- Carbon credits in some regions
By combining multiple income sources, farmers can secure more stable earnings compared to traditional farming.
Costs to Consider
Agrivoltaic systems generally cost more than traditional solar farms due to:
- Stronger mounting structures
- Higher panel elevation
- Additional engineering
- Customized spacing
- Increased labor
However, these costs are often offset by long-term energy and crop revenue.
Payback Period
Depending on region and incentives, typical payback periods range from:
- 5 to 12 years for small systems
- 10 to 15 years for large elevated systems
Once paid off, the system provides low-maintenance energy for 20 to 40 years.
