European Agrivoltaics: Facts and Figures

Agrivoltaics in Europe integrates solar panels with agriculture to simultaneously boost crop productivity, conserve water, generate renewable energy, and provide economic and environmental benefits, with the EU aiming to meet ambitious solar targets by deploying agrivoltaics on just 1% of arable land to optimize land use and support climate goals despite challenges in design and crop selection.

Agrivoltaics is an emerging approach in the renewable energy sector that optimizes land use efficiency by combining agriculture and photovoltaic (PV) systems. This dual-use concept allows for simultaneous crop cultivation and solar energy production, typically by installing solar panels above or alongside agricultural fields or grazing land. The synergy between food production and renewable energy generation offers several benefits:

  • Increased crop productivity: Solar panels provide shade, reduce evaporation, and minimize water requirements, acting as a protective canopy that can improve crop yields.
  • Energy generation: The system generates clean, renewable energy, reducing greenhouse gas emissions and reliance on fossil fuels.
  • Water conservation: Shading from panels helps conserve water, especially valuable in arid regions.
  • Economic benefits: Farmers can generate additional income by selling electricity back to the grid and lowering their own energy costs.
  • Land preservation: Dual use helps preserve agricultural land and biodiversity, preventing conversion to other uses.
  • Climate change mitigation: Reduces emissions and promotes sustainable agriculture.

Challenges include the need for careful system design, crop selection for shaded conditions, and ensuring economic viability. Ongoing research aims to optimize designs, assess crop performance, and evaluate feasibility across regions.

Agrivoltaics in Europe

To meet increased renewable energy targets, the EU must install at least 710 GW of solar by 2030, requiring about 80 GW per year (up from 40 GW in 2022). This scale demands significant land, making agrivoltaics a promising solution for efficient land use. The EU has 170 million hectares of agricultural land, with 94 million hectares arable. Deploying 900 GW of agrivoltaics would require just 1% of EU arable land (950,000 hectares), compared to 10 million hectares used for biofuels.

The European Commission’s Solar Energy Strategy encourages member states to promote agrivoltaics and implement supportive policies. The SolarPower Europe Best Practice Guidelines for Agrisolar provide advice for successful project development.

Country Initiatives

  • Italy: Allocated €1.1 billion for agri-PV and €1.5 billion for agrisolar, aiming for over 1 GW of development. Italy has a regulatory framework defining agrivoltaics.
  • Austria: Federal law includes agri-PV support with a 30% additional investment subsidy.
  • Germany: Established the DIN-SPEC 91434 technical norm for agrivoltaics in 2021, with plans to expand. Held first agri-PV and floating solar tenders in 2022.
  • France: Largest agri-PV market in Europe, driven by innovation tenders. The 2023 renewable energy law defines agrivoltaic systems to balance food sovereignty and energy independence.
  • Netherlands: Supports agri-PV through its CAP Strategic Plan, requiring PV not to interfere with agriculture and setting criteria for module distribution.

Future Predictions

  • Scaling up: The agri-PV sector is expected to mature, with projects moving from MW to GW scale. The focus will be on cost reduction, policy development, and collaboration with agriculture.
  • Agritech innovation: Integration of renewable energy, technology, and sustainable practices will drive productivity and address environmental challenges.
  • Simulation tools: Tools like PVcase Yield will be important for sustainable scaling, enabling better analysis of PV-agriculture interactions, especially shading.

How Agrivoltaics Works

  1. 1.Site selection: Based on land availability, solar potential, soil quality, and infrastructure proximity.
  2. 2.Solar panel installation: Panels are mounted above or alongside fields, on poles, frames, or integrated into existing structures.
  3. 3.Design considerations: Factors like tilt, height, spacing, and orientation are optimized for energy generation and minimal crop shading.
  4. 4.Crop selection: Shade-tolerant crops (e.g., leafy greens, herbs) are chosen for compatibility.
  5. 5.Shading and microclimate: Panels create favorable conditions by reducing sunlight and temperature extremes, improving water efficiency.
  6. 6.Resource management: Irrigation and nutrient management are adjusted for the altered microclimate.
  7. 7.Energy management: Electricity generated can power farm operations or be fed into the grid, with possible compensation through net metering or incentives.
  8. 8.Maintenance and monitoring: Regular upkeep and performance tracking for both panels and crops.

Agrivoltaic systems can be adapted for row crops, orchards, vineyards, and greenhouses, with design tailored to local conditions. The field is still developing, with ongoing research into system optimization and economic assessment.
