Stress hydrique, brûlures du feuillage, sécheresses répétées : les exploitations de grandes cultures encaissent directement les effets du changement climatique. L’agrivoltaïsme permet de maintenir l’activité agricole de la parcelle tout en produisant de l’électricité.
Sur les céréales comme sur les légumineuses, l’objectif reste le même : créer un micro-climat plus favorable à la plante, assurer la protection des cultures et sécuriser les rendements, sans contrainte sur le passage du machinisme. Ombrea conçoit, dimensionne et exploite ces installations à partir de votre itinéraire technique.
- Hydric and thermal stress (scorching and drying of crops)
- Climate change and hazards
- Yield and sustainability of farms
- Environmental and biodiversity issues
Faced with these many challenges, agri-energy is the solution of choice to support agriculture in its transition and combat the effects of climate change.
Elles permettent aux exploitations de grandes cultures de mieux maîtriser leurs besoins en eau et de diversifier leurs revenus en produisant une énergie renouvelable, tout en devenant actrices de la transition énergétique.
Ces bénéfices agronomiques sont mesurés sur nos sites en exploitation. Au Channay, en Côte-d’Or, les rendements relevés en zone ombrée en 2023 ont progressé pour le blé comme pour les lentilles, dans un contexte de faibles précipitations. Les résultats détaillés figurent dans nos réponses à vos questions, en bas de page.
Deux technologies photovoltaïques sont particulièrement adaptées aux grandes cultures. Dans les deux cas, les rangées sont implantées sur des bandes enherbées, en parallèle des cultures, afin de maintenir le libre passage du machinisme agricole sur la parcelle. Le choix de la technologie et l’écartement des panneaux sont définis en phase de développement du projet, à partir de vos rotations et de vos pratiques agricoles.
- Thanks to a panel control algorithm, crops are given more favorable conditions in which to grow.
• Ces structures aux panneaux rotatifs permettent de moduler l'ombre au fil de la journée selon les besoins de la culture en place.
- This system of fixed panels, similar to hedges, creates a windbreak effect with the advantage of protecting crops.
• Il suit la même logique d'implantation que les trackers en bordure de rangs afin de préserver la mécanisation de la parcelle
To meet the many challenges they face and ensure the long-term viability of their operations, farmers can become players in the energy transition through agri-energies. These represent all sources of energy production derived from agricultural activities, including agrivoltaics.
Agrivoltaics is the practice of combining solar energy production with agricultural production, in synergy. Its aim is to bring benefits to the farm while producing renewable energy.
Our teams have developed tools that enable us to determine, during the development phase, the technology best suited to field crops, as well as to the farmer's itinerary and farm machinery. Panel height, spacing and sensors can be adapted to the needs of the crop in question.
Every project is designed with respect for the site, from its construction using reusable, recyclable materials and a structure that limits the artificialization of the soil, to its dismantling with a site that respects the soil, biodiversity and local culture.
Ombrea offers two particularly well-suited agrivoltaic technologies for field crops:
Today's field crop farms face a number of climatic and environmental challenges. Rising temperatures lead to a drop in flowering, and increasing drought to a shortage of water, resulting in a drastic drop in field crop yields (Agreste, 2021).
Agrivoltaics can provide solutions to these problems. By way of example, here are some of the results gathered from our Channay site in the Côte d'Or (21), for the year 2023:
Launching an agrivoltaic project for field crops requires the same actions as for any other type of crop. There are 3 distinct steps to follow.
Initially, project definition and qualification enable us to validate the solution adapted to your needs and your operation, and to verify its feasibility. This is followed by contractualization and development, with the aim of validating the project with the relevant authorities. Finally, once the project has been finalized, Ombrea operates the plant, aiming for optimum synergy between field crop protection and renewable energy production.
