In this installation carried out in Murcia by DIGIMASTER, a solution has been chosen with precast concrete supports for solar panels on flat roofs, combined with a 50 cm ballasted system to ensure the stability of the installation.

The installation has been executed in a horizontal layout with a 30º inclination, an ideal configuration for roofs where the aim is to optimize solar exposure and improve structural safety.

The use of the 50 cm ballast provides rigidity and stability against wind stresses, avoiding the need to drill holes in the deck and ensuring a safe and durable installation.

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 in a horizontal arrangement without the need for mechanical anchors.

The panels are placed on compact concrete structures that facilitate a correct inclination and distribution on the roof. This type of support acts simultaneously as structure and ballast, eliminating the need for complex metallic systems.

Main advantages:

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

50 cm ballasted system

The system used is based on concrete supports that provide their own weight and an additional 50 cm ballast as a fastening element, avoiding perforations in the roof. This reinforcement guarantees high structural stability even in demanding wind conditions.

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
A demountable solution is needed

Optimized deck layout

The horizontal configuration with a 30º inclination allows for an efficient distribution of the solar modules, optimizing the available space and improving solar gain.

Benefits:

Maximize the number of panels installed
Maintain correct row spacing
Facilitate access for maintenance
Improve the organization of the system
