1.3. Static analysis For the structural analysis of the lamppost, the geometric 3D modeling software SOLIDWORKS was used, where the structure of the lamppost was modeled, consisting of a lower square tubular section and a upper circular section, as well as a latticed tubular structure to support and fix the solar panels. The characteristics of the materials used are summarized in Table 1.

Considering the wind action, the snow action, and the structure's self-weight, the boundary conditions presented in Table 2 where obtained.

The definition of the boundary conditions consisted in applying the vertical and horizontal forces at their respective application points, as well as defining the surface of the pole base as fixed, as shown in Figure 2.
