<p>Failures in technical systems lead to damage to equipment and economic losses. Reliability is one of the main concerns in all automated control systems. Studying the impact of technological factors on product reliability and eliminating them is a critical task. When designing any new device, evaluating its reliability is a crucial indicator in determining whether the associated costs are justified. This article focuses on solving a practical issue by evaluating the reliability of a solar-powered device for the primary processing of silkworm cocoons. The device plays an important role in the sericulture industry, and its reliability directly affects economic efficiency. The study uses exponential distribution laws and mathematical modeling methods to assess reliability. Various coefficients were considered in calculating the failure intensity of the device’s components, bringing the results closer to real-life conditions. Factors such as thermal and electrical loads were identified as primary indicators affecting device reliability. The research results led <br /> to specific recommendations for improving device design, including the use of high-quality thermal insulation materials, enhancing the durability of solar panels, and implementing automatic temperature and humidity control systems.</p>
