Agrivoltaics in Spain: Olive Oil and Solar Power on One Farm 2026

Agrivoltaics in Spain is moving from concept to reality as a major olive oil producer builds one of the country's largest dual-use solar projects. The initiative in Vilches, Jaén, shows how food and electricity production can share the same land instead of competing for it.

Spain's Land Competition Between Solar and Agriculture

For years, Spain has faced a difficult trade-off. Solar developers want flat, sunny land near the electricity grid, and farmers need the same terrain for crops. This competition has slowed renewable energy deployment in some regions and raised concerns about food security.

The project in Vilches offers a different approach: rather than choosing between olive oil and electricity, the same parcel will produce both. It is a response to a problem that has frustrated both industries.

The Jaén Solution: 5,150 Panels Above an Active Olive Grove

Acesur, a leading olive oil company, has started construction next to its packaging plant in Vilches. The project will have 3.65 MWp of capacity using more than 5,150 photovoltaic modules installed directly over a traditional olive grove that remains in production.

Unlike a conventional solar farm, 100% of the trees will stay in the ground. Agricultural activity will continue beneath the panels, and the electricity generated will be used for Acesur's industrial self-consumption. The same plot will yield olives while producing power.

Why Height Is the Secret to Agrivoltaics Success

The olive trees in this grove are relatively short, typically around two meters. However, the height of the solar installation is not determined by the trees themselves but by the harvesting machinery that must operate among them.

Harvesters used in traditional olive groves can reach about 3.5 meters as they straddle the rows, grip the trunks, and shake the olives loose. Therefore, the panels will be mounted at more than four meters above the ground to allow these machines to pass underneath without obstruction.

This design choice is critical: it ensures that farming practices remain unchanged and that the solar infrastructure does not interfere with the annual harvest.

Key Takeaways from the Vilches Agrivoltaic Project

• Dual land use: The project demonstrates that solar and agriculture can coexist on the same parcel, reducing land-use conflicts.
• Scale: With 5,150 panels and 3.65 MWp, it is one of Spain's largest agrivoltaic installations.
• Height matters: Panels are elevated above four meters to accommodate standard olive harvesters.
• Self-consumption: The electricity generated will power Acesur's nearby packaging plant, lowering energy costs and emissions.
• Tree preservation: All olive trees remain in production, ensuring no loss of agricultural output.

What This Means for Farmers and the Energy Transition

The Vilches project is a test case for whether agrivoltaics can be scaled in Mediterranean crops. If successful, it could provide a model for other olive growers and farmers facing pressure to sell land to solar developers.

It also addresses a common criticism of renewable energy: that it competes with food production. By keeping the grove productive, the project maintains agricultural jobs and output while adding a new revenue stream and clean energy source.

For Acesur, the benefits are clear: reduced energy costs, a lower carbon footprint, and a demonstration of environmental stewardship. For Spain, it is a step toward meeting renewable energy targets without sacrificing its iconic olive landscapes.

Challenges and What to Watch Next

Agrivoltaics is not without challenges. The elevated structures increase installation costs, and the shading from panels can affect crop yields, although the impact on olives is still being studied. Maintenance must also be coordinated with farming schedules. The background to this story is set out in Off-Grid Solar Power for Pistachio Processing Plant.

Observers will watch how the olive trees perform under the panels over the coming seasons. If yields remain stable, the model could spread to other regions with similar crops, such as vineyards or almond groves.

Policy support will also be crucial. Spain's current regulations are not fully adapted to dual-use projects, and clearer rules could accelerate adoption. The Vilches project may serve as a catalyst for such changes. Context on how this played out before sits in Spain and Portugal Olive Mills Face 27% Closure Crisis.
