In this installation at the University of Almeria, a solution with precast concrete supports for solar panels on flat roofs was chosen, using a ballasted system without perforation.

The installation combines horizontal configurations with optimized inclinations (approx. 10º-15º), ideal for technical roofs where the aim is to maximize energy production without compromising the building structure.

This system allows a fast, safe and efficient installation, adapting perfectly to large roofs with technical obstacles such as skylights, air conditioning machinery or architectural volumes.

Concrete supports for flat roof installations

In this installation, concrete supports specifically designed for flat roofs have been used, allowing the installation of solar panels without the need for mechanical anchors.

As shown in the images, the panels are arranged in aligned rows on compact concrete structures, optimizing the available space and facilitating roof distribution.

This type of support acts simultaneously as structure and ballast, eliminating the need for additional metallic systems.

Among its advantages are the following:

Installation without drilling holes in the roof
Waterproofing protection
Reduced assembly times
Increased wind stability
Virtually no maintenance

Ballasted system without drilling

The system used in this installation is based on concrete supports that provide their own weight as a fastening element, avoiding perforations in the roof.

This type of solution is especially important in buildings such as the University of Almeria, where the integrity of the roof is a critical factor.

The concrete supports are designed to offer high structural stability due to their weight and geometry, and can even be supplemented with additional ballast if necessary.

This system is ideal when:

The cover cannot be drilled
The aim is to avoid leaks or structural damage
Fast and clean installation is required
Reversible or demountable solution needed

Optimized distribution on the technical roof

One of the most outstanding aspects of this installation is the adaptation to the environment of the roof, where there are multiple technical elements such as:

Skylights
Air conditioning equipment
Architectural volumes
Passage and maintenance areas

The concrete supports allow great flexibility in the distribution, facilitating the layout of the installation around these elements without the need for structural modifications.

This allows:

Making the best use of the available surface
Maintain technical access
Avoid shadows between modules
Optimize solar orientation

Photovoltaic installations in public and university buildings

Installations with concrete supports in buildings such as the University of Almeria are becoming more and more frequent, as they allow the implementation of sustainable solutions without affecting the existing structure.

The use of ballasted systems in this type of projects allows:
