Our dedicated solution for your vineyards

Controlled rotating shade

- Thanks to a panel control algorithm that integrates real-time micro-climate data from sensors on the plot, crops are provided with favorable conditions in which to grow. Plants' access to light is prioritized during stages such as flowering, when sunshine is crucial.

Our answers to your questions

What are agri-energies?

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, which technology is best suited to the vineyard, the operator's itinerary and the farm machinery. The height and spacing of the panels and the sensors used with the technologies can be adapted to the needs of the vineyard in question.

Every project is designed with respect for the vineyard plot, 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 culture.

With 8 years' experience in agrivoltaics, Ombrea has the expertise to carry out projects with real agronomic and climatic benefits for protected vineyards. To discover our results on a viticulture demonstrator site : Rians agrivoltaic site - Ombrea.

Ombrea can implement a range of technologies adapted to the specific needs of each operation. 

For viticulture, the most suitable technology is the piloted rotating shade, whose axis of rotation can reach heights of 4 or even 5 meters. It is therefore perfectly suited to vineyards and agricultural machinery, in particular harvesters up to 3 meters high.

The panels are controlled by algorithms that integrate real-time microclimate data from the plot's sensors. This enables us to create optimal conditions for the vines' development.

Agri-energies can provide many services for tree farms. By way of example, here are some climatic results gathered on our Caladoc and Grenache sites in the Var (83) in 2021-2022:

  • Reduced summer temperature peaks: 51% reduction in periods when temperatures exceed 35°C. 
  • 66% reduction in periods of aggressive sunlight that can damage crops (leaf burn). 
  • Systematic reduction in soil temperature under controlled shading (-4°C at -10cm depth in summer).

To launch an agrivoltaic project, in viticulture as in any other type of crop, you need to follow 3 distinct steps.

First, project definition and qualification enable us to validate the solution best suited to your needs and operations, 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 completed, Ombrea operates the plant, aiming for optimum synergy between vineyard protection and renewable energy production.
