Ground screws and screw piles for solar panel mounting
Ground-mounting structures for solar panels on screw foundations, with precise alignment and no concrete.
Suitable for
Concrete scenarios where this solution works well.
Residential ground-mounted solar installation
When the roof is not sufficient or not optimally oriented, we install at ground level, with a tilt calibrated for your location.
Small or medium solar farm
Rows of precisely aligned supports, screw foundations, optimised spacing. Ready for panel installation the next day.
Installation on agricultural land
Foundations that do not permanently block the land and are reversible if the plan changes. Access between rows is preserved.
Off-grid or self-consumption system
A few rows of panels for a household or business, fast installation, no complex design, no concrete.
What’s included
What you get when you work with Martetic on this solution category.
- Assessment of ground, orientation and optimal tilt
- Installation of screw foundations per row
- Support structure installation: longitudinal bars and cross-members
- Row alignment and laser verification of the tilt
- Transport of equipment and clean-up at handover
How it works
The main steps from order to handover, for this category.
Assessment and planning
We check the ground, the orientation, the number of rows and the spacing. We determine the optimal tilt for your location.
Foundation installation
Screw foundations positioned precisely on each panel row. No concrete, no excavation.
Support structure installation
Bars, cross-members and fixing systems, installed, aligned and checked by laser.
Verification and handover
We check the tilt, the alignment between rows and the stability. We hand over ready for panel installation.
Advantages
What makes this solution better than the classic alternatives.
No concrete
Faster installation, recoverable land if the plan changes, a smaller footprint than classic foundations.
Precisely calibrated tilt
We don't estimate the tilt; we check it by laser for every row. Maximum output from the installation.
Fast
Foundations and structure installed in 1–2 days. The panel installer can start immediately afterwards.
Extendable later
We add rows if you expand the system. The same technology, compatible with the existing structure.
Products that may be considered
The options below are a starting point. The final selection is confirmed after the structure, ground, loads, connection and installation conditions.
G, M, V or Custom, depending on geometry, groups and maintenance
What you need to send us
The location, dimensions, the sketch or plan, known weight or loads, photographs of the ground and the desired deadline.
What we check
The ground, access, bearing points, the connection to the structure, vertical and lateral loads and the possibility of installation.
Frequently asked questions
What customers usually ask about this category.
Any fixed angle between 10° and 35°, calibrated to the latitude and orientation of your site. On request, we can prepare the structure for a manually adjustable angle.
It depends on the panel dimensions and the row length. We calculate the layout at the assessment. We have no fixed number; we adapt to the project.
Yes. Screw foundations compensate for level differences on a gentle slope without extra earthworks. On a steep slope, we discuss the right solution.
For small and medium residential systems, usually not. For solar farms or systems with large areas, we recommend a technical design.
Yes. We add rows using the same technology. We plan the correct spacing from the start if an extension is likely.
