Vineyard agrivoltaic structure

Overview
Sun'Agri offers a dynamic agrivoltaic solution designed to protect vineyard plots from climate hazards while producing electricity. The system reduces vine water stress, preserves buds and secures yields by modulating sunlight above the rows.

Measured results

• Leaf temperatures up to 5 °C cooler thanks to dynamic shading.
• Up to 60% water savings reported in specific cases.
• 41% average water savings reported.
• Average yield increase of +30% observed in protected areas.
• Up to +2 °C at night in late-frost conditions (anti-frost effect).
• Up to -4 °C under louvers during heatwaves (cooling effect under louvres).

Trial results (Piolenc / summer 2023)

• Irrigated area: 8% significant damage under dynamic agrivoltaics versus 40% in the control plot.
• Non-irrigated area: 30% damage under dynamic agrivoltaics versus 75% in the control plot (2.5× reduction).
• After the heatwave: higher losses in the irrigated control (40%) than in a protected non-irrigated area (30%).
• Up to +39% must yield at pressing compared to controls.

Technology

• Mobile solar louvers installed about 5 m above the rows to modulate sunlight.
• AI-based system controlling real-time panel inclination according to vine phenology and weather forecasts.
• Robust, demountable and recyclable installation designed for a 30-year lifespan.
• Compatible with mechanization and vineyard operations (vehicle passage and row maintenance).

Fine light control

• Louver orientation up to 90° to balance light between the vine and electricity production.
• Control based on production targets, real-time agroclimatic and physiological sensor measurements, and weather forecasts.
• Goal: full sunlight when needed, targeted shading during heatwaves or frost risk.

Agronomic monitoring and application

• Each project is monitored by agronomy engineers with a control plot for comparison.
• Sun'Agri app provides real-time visualization of louver control and agronomic and weather data.
• Custom alerts (heatwave, frost risk).
• 30 hours/year of autonomous panel control included (manual override possible for machinery passage or emergency decisions).
• App awarded (Focus Innovation 2024 mentioned).

Key solution points

• Controlled microclimate protecting vines from thermal stress and climatic hazards.
• Regular agronomic monitoring with control plots and a dedicated app.
• Low ground footprint, adapted to farm operational realities.

Technical characteristics / specifications

• Louver installation height: approximately 5 m above the rows.
• Louver inclination: adjustable up to 90°.
• Designed life: 30 years (robust, demountable and recyclable installation).
• Materials: European recycled or recyclable steel (structure).
• Control: artificial intelligence, agroclimatic and physiological sensors, integration of weather forecasts.
• Operational capabilities: compatible with mechanization (vehicle passage, treatments, maintenance).
• Service included: 30 h/year of autonomous control and agronomic monitoring by engineers.
• Field-reported performance: observed water savings (up to 60% in some cases), average yield gains (+30%) and reduced damage from heat and frost (e.g. 8% vs 40% in irrigated areas).
