Grupo Solaria has relied on SOCOTEC's experience in geotechnics for photovoltaic parks for its new plant in the municipality of Mansilla de las Mulas, León, Spain. This photovoltaic plant of approximately 50 MW covers an area of 137.45 hectares and has an investment of more than 27 million euros.
The geotechnical study included a complete evaluation of the terrain, including boreholes, penetrometers, electrical and thermal resistivity tests, as well as Pull-Out Testing (POT). These analyses were crucial to define the viability of the projected structure and ensure the stability of the photovoltaic panels under different conditions.

Pull-Out Testing:
The extraction test, also known as Pull-Out Testing, was fundamental in the evaluation of the behavior of the profiles used in the support structures of tables or photovoltaic panels. This test, which combines lateral and compression/extraction loads, made it possible to determine how the profiles would behave under various ground conditions. By applying determined and increasing forces, vertical and horizontal deformations were evaluated, using a micrometer for measurement. This data was essential to ensure that the proposed structure met the necessary requirements for strength and stability.

Deployment and Movement of Machinery
The deployment of machinery was a crucial part of the project, involving specialized equipment such as drilling machinery, dynamic penetrometers, driving machinery and backhoes. In addition, tools for measuring forces and displacements in profiles, such as dynamometers and comparators, were used to ensure the accuracy of the measurements made throughout the process.7
