The article presents the results of a study on the problems associated with the long-distance transportation of solar collector evacuated tubes. Using deliveries to the city of Yakutsk as an example, it is shown that a significant number of evacuated tubes can be damaged during transit, even on paved roads. To identify the causes of tube failure, a damage analysis was conducted. This analysis revealed characteristic failures caused by the bending moment under vibrational and impact loads. Based on a study of the tube design and their packaging, calculation models for the outer and inner bulbs were developed for subsequent strength analysis.
