In this installation in Murcia, a photovoltaic structure was assembled using 15º precast concrete supports in a horizontal arrangement, combined with 50 cm ballasts to guarantee the stability of the system.

This type of solution is ideal for flat roofs with gravel, as it allows for installation without perforations, fast and highly resistant to the action of the wind, taking advantage of the weight of the system itself as a fastening element.

Horizontal 15º concrete support for flat roofs

The 15º concrete support allows the solar panels to be installed horizontally, a configuration widely used when seeking to maximize the power installed on the roof and to adapt to different roof geometries.

The 15-degree tilt provides an optimal balance between energy efficiency, structural stability and ease of installation.

In this installation in Murcia, the supports have been placed directly on the waterproofed roof by means of a ballasted system, which allows:

Do not perforate the waterproofing
Maintaining the integrity of the cover
Reduce installation time
Proper distribution of loads on the surface
Adapting to urban environments with different wind conditions

50 cm ballast reinforcement

The use of 50 cm ballast provides stability to the structural assembly, being an efficient solution when seeking a balance between weight, ease of handling and structural performance.

This type of ballast is recommended when:

Stability is needed without adding excess weight
The roof allows for homogeneous load distribution
Fast and efficient installation is sought
Reliable solution required without mechanical anchors

The ballasted system with concrete support and 50 cm ballast allows for safe, durable and non-interventional installations on the roof.
