Innovative cultivation and processing facilities are needed in order for the increased production in Türkiye to be efficient, low energy consumption, and high quality. Therefore, an in-depth analysis of the US California-based walnut producer has been made, which can also be an industrial role model to Turkish producers. The orchard of Chandler variety walnut was 70 decares and contains 17-year-old trees. Fuel consumed by agricultural machines during field operation, the rate of meeting the electricity need from solar panels for irrigation and processing, and the data of the hybrid drying (solar wall-natural gas) which is one of the few agricultural applications samples in the world were recorded for sustainable walnut production. In walnut production, spraying (pesticide) had the highest fuel consumption by far compared the all-year applications. The photovoltaic panels in the orchard met 62.8% of the required energy for irrigation engines. To process 42837 kg of walnuts, it was determined that 18.05% of the daily produced energy by roof-top photovoltaic panels was used. It is presenting that walnut production makes a significant direct contribution to the economy as a result of high-quality products with full mechanization and methods of utilizing solar energy technologies in walnut production.
