At Gaec Des Taillis in Sion-les-Mines, Laurent and Sandrine Aragon utilize a solar tracker and a battery storage system to optimize electricity consumption for their dairy farm. Installed by OKWind, the solar tracker generates electricity to power farm operations and charge the battery, which stores excess energy for nighttime use.

The system shows daily self-consumption rates from 60% to over 90% in summer and 10% to 60% in winter, with an average annual autonomy of 52-53%. The couple anticipates a 12-year payback period for the battery installation.
