When designing and specifying the assumptions for free-field solar installations, data concerning the soil and other local conditions is of utmost importance. It allows for optimizing of construction works, avoiding down-time, reduction of performance during operation or quick damaging of the installation.
- Geological, hydro-geological and soil conditions, soil chemistry conditions
- Morphological, hydraulic, climatic and sociological conditions in the location
It is concluded by specification of conditions for an enterprise performing construction works from the perspective of location of solar panels and designing of the installation, taking into account the access roads, drainage or ground surface
Probing with a driving rod
The depth of loose clastic rock deposition is determined by light probing using a driving rod.
Bore hole detection
Considerations are based on the fact that the parameters determining the load-bearing capacity of the steel piles derive from varying soil structures and their respective different force-bearing capacities. It is, therefore, advisable to pay special attention to the examination of the uppermost 2 to 4 meters of the soil stratum.
Trial pile driving
In these trials a steel pile is usually driven into the soil that needs to be examined.
The activities necessary should be well coordinated, preferably - done by a single person. This allows to avoid errors in transfer of information and information losses while communicating, warranting quick performance of activities aimed at a specific objective.
Such preliminary investigation of local conditions serves very well as a basis for a precise design of a solar installation. The results can be easily transferred to other layouts (e.g. geodetic layout, installation layout), and they enable precise designing of the panels, taking into account their location. Construction difficulties associated with the soil conditions are reduced to a minimum, while maximum design safety is achieved. In this way, it is also possible to avoid long-term difficulties with operation of the installation due to external conditions, associated with the location (e.g. excessive erosion).
