The projected growth of solar energy in 2025 is driving a clear evolution in the design and selection of photovoltaic structures. Installers and industry professionals are seeking faster-to-assemble, safer solutions that are adaptable to different types of roofs.
In this article we analyze the 5 most used solar structures in 2025 , why they are gaining prominence and which one to choose according to your project.
1. Ballasted structures for flat roofs
Ballasted structures remain the most installed option on industrial roofs, especially in logistics warehouses and factories.
Why are they ideal?
-
- They do not require deck drilling.
- Quick and safe installation
- Compatible with TPO type covers
- Reduction of leak risks
Ideal for:
-
- Industrial roofing
- Projects where drilling is not allowed
- Self-consumption installations
2. Coplanar structures
Coplanar structures are used on sloping roofs, where the panels are placed parallel to the roof.
Main advantages:
-
- Aesthetic integration
- Less visual impact
- Good wind resistance
Most common applications:
-
- Industrial roofs with single sheet metal
- Residential dwellings with tile or sheet metal roofs
3. Structures with optimized inclination
More and more projects are opting for structures that maximize production through a specific inclination.
Why they’re growing in 2025:
-
- Greater energy efficiency
- Orientation optimization
- Improving the project’s ROI
Widely used in:
-
- Large industrial facilities
- Rooftop photovoltaic plants
4. Elevated or canopy-type structures
Elevated structures allow for the use of spaces such as parking lots or open areas.
Key trends:
-
- Integration with electric mobility
- Shadow generation + energy
- High profitability in parking lots
Use cases:
-
- Company parking lots
- Shopping centers
- Service areas
5. Ground-mounted structures
Ground-level installations remain key in large-scale projects.
Advantages:
-
- Maximum design flexibility
- Greater generation capacity
- Easy maintenance
Highlights include:
-
- Solar farms
- Utility-scale projects
- Agricultural installations (agrivoltaics)
Which solar structure should you choose in 2026?
The choice depends on several factors:
- Type of roof or terrain
- Local regulations
- Allowable structural load
- Energy production target
In industrial projects, ballasted structures continue to lead due to their balance between safety, cost and speed of installation.
