Types of supports for solar panels: fixed or adjustable structures
What are the differences between the different types of supports for installing solar panels? On our website you can find different fixed or adjustable structures. Would you know how to choose the most appropriate one based on the needs of the surface on which the installation is going to be carried out? What other factors must be taken into account? We explain it to you:

Choose the appropriate support for the installation of solar panels according to the inclination

When choosing a structure for the installation of solar panels , we must look at certain factors that help us optimize their performance . The goal is to ensure safety and maximize energy efficiency.
One of the most important aspects to take into account is the inclination , something essential to be able to optimize the angle of the panels in relation to the sun, and one of the reasons why there are differences between flat roofs and inclined roofs.
For example, on roofs or flat surfaces, we will need supports with a certain inclination that allows us to find that perfect angle with the sun.

The supports available at Charmex SA and their characteristics:

We can find supports with a fixed inclination or with an adjustable inclination. Identify which one we need and obtain all the added benefits that they can provide. We must also take into account aspects such as latitude, climatic conditions, or the region in which we are located . In this way, in a place with strong solar irradiation, we could put a lower inclination, while, in an area with adverse climatic conditions, such as strong gusts of wind, we must have additional measures that provide greater safety. to the fixings of the solar panels, such as ballasts for greater fixation.

Features of Adjustable Triangle Brackets

Types of supports for solar panels: fixed or adjustable structures

Adjustable triangular supports

The adjustable triangular supports allow you to modify the inclination angle of the solar panels. This is especially useful for optimizing solar energy collection depending on the seasons or for adjusting the optimal angle regardless of the original orientation of the surface.

  • Flexibility in installation.
  • Maximization of energy efficiency.
  • Adaptability to seasonal changes.

Suitable surfaces:

On flat roofs, it allows the angle to be adjusted regardless of the orientation of the surface. They can also be suitable for inclined roofs, since the angle can also be adjusted depending on the needs until the desired angle is achieved.

Features of fixed triangular supports

Fixed triangles maintain a constant angle and cannot be adjusted once installed. They are designed to provide a specific and constant inclination.


They have great stability and durability as they have no moving parts.

At Charmex SA you can find two types of fixed triangular supports:

Fixed triangular supports

  • Suitable for roofs without a perimeter balustrade, that is, without a safety railing. It offers stability and security, something necessary when you do not have the security that this type of railing would provide. This support facilitates both installation and maintenance.
  • Its 10º inclination means that exposure to the wind is reduced, so only a low ballast load would be needed.
Suitable surfaces:
  • They are suitable for flat roofs where the optimal angle has been calculated, or for roofs with a slope that coincides with the appropriate angle for solar collection.

Triple Support Triangles

The triple structure provides great stability, making it wind-resistant and ideal for areas with adverse weather conditions.
It is ideal for large surfaces (such as commercial buildings) and open spaces.

Suitable Surfaces:

They are ideal for ballast systems, that is, for those situations in which it is necessary to stabilize the supports on surfaces where drilling cannot be done, a characteristic that can be common on flat roofs.

To consider:

The fixed support triangles that you can find on our website can be made to measure.
It is necessary to have enough space to be able to distribute the weights correctly. You must also ensure that the roof can support sufficient weight of the ballast material.
