Specialists in Geotechnics for Photovoltaic Parks
At SOCOTEC, we are leaders in the geotechnics sector for photovoltaic parks, with more than 12 years of experience and more than 300 completed projects. Our team of experts offers a comprehensive 360º Engineering service, ensuring the solidity and durability of solar infrastructures through accurate and reliable geotechnical studies.
Geotechnical Services for Photovoltaic Projects
We carry out a wide range of specific geotechnical tests and studies to guarantee the viability and stability of solar plants:
Specialized Geotechnical Testing:
Advanced technologies for soil study
- Drone surveying: High-precision geospatial data capture for digital terrain modeling.
- Topographic survey with GPS station: Obtaining georeferenced coordinates for a detailed and accurate design of solar installations.
Hydrological studies
Hydrological studies are essential to evaluate the effects of water on photovoltaic plants. SOCOTEC analyzes the hydrology of the terrain to foresee possible drainage and erosion problems, ensuring an infrastructure resistant to climatic and environmental conditions.

CORROSIVITY
Ground and atmospheric corrosivity tests
Ground and atmospheric corrosivity tests
Corrosivity of the ground
The analysis of ground corrosivity is key to determine the impact of the soil on metal foundations. SOCOTEC evaluates factors such as conductivity, humidity, pH and contaminants, classifying the corrosivity according to DIN 50929-3.
Atmospheric Corrosivity - Wire-on-Bolt Test
SOCOTEC uses the Wire-on-Bolt test to measure environmental corrosivity in metal structures. The methodology is based on the mass loss of metal samples exposed to different climatic conditions, allowing the aggressiveness of the environment to be classified.

PULL-OUT TESTING
Extraction Test
Pull-Out Testing is a key test in photovoltaic geotechnics, designed to evaluate the strength and behavior of anchor profiles used in solar panel support structures.
How is Pull-Out Testing performed?
This test consists of applying a controlled force on the piles previously installed on the ground. Specialized equipment is used to measure the vertical and horizontal deformations that occur when the poles are subjected to progressive extraction and compression loads. The results obtained allow us to determine the capacity of the ground to resist external forces and guarantee the structural stability of the photovoltaic installation.
At SOCOTEC, we apply advanced methodologies and state-of-the-art equipment to perform Pull-Out Testing with the utmost precision, ensuring that the foundations of solar plants are safe and durable.
