Concrete blocks vs. aluminum structures for photovoltaic panels on a flat roof

Choosing the right structure for installing photovoltaic panels on a flat roof is a key factor in utilizing solar energy. There are significant differences between the two mentioned types of structures - concrete blocks and aluminum structures. In this article, we will focus on the advantages of concrete blocks.

Installation without drilling – no holes in the roofing

One of the main advantages of concrete blocks is that they are a non-invasive structure. They do not require any drilling or damaging of the roofing membrane, which means they preserve the roof surface and minimize the risk of water leakage.

Attaching panels using clamps to the structure

A few minutes – measurement, spacing, and ready

Another important factor is the speed of installation. Concrete blocks offer a simple and efficient assembly method. These blocks can be easily moved on the roof and positioned at desired locations.

Arrangement of Enbra blocks

As a result, the installation of photovoltaic panels is quicker compared to metal structures, which require more precise measurements, cutting, and assembly. Also, adjustments are more difficult with metal structures if measurements are not exact. Blocks can be easily repositioned if needed.

Arrangement of concrete structures

The simplicity of installation is an undeniable advantage of concrete blocks. The entire installation process is intuitive and does not require specialized installation technicians or special tools. The blocks need to be placed and then panels are attached to them using standard anchoring material (M8 screws - included in every order, and chosen center or edge clamps - to be purchased as needed). This makes installation easier for both professional installation teams and homeowners who decide to do the installation themselves.

Mounting panels on concrete blocks

No additional load needed for fixation

Blocks also eliminate the need for additional load on the roof structure. Due to their weight of 46 kg, this structure is already stable enough, and there is no requirement for extra stabilization for securing the panels. This reduces costs and simplifies the overall installation process.

Longevity without corrosion

It's also worth mentioning that concrete blocks provide stability and resistance to weather conditions. They are designed to withstand strong winds, snow, and other external influences. This ensures the long lifespan and reliability of the photovoltaic system on the roof.

Adjust panels as needed

Flexibility in orienting photovoltaic panels is another key advantage of concrete blocks. With this type of concrete structure, panels can be easily adjusted to different orientations to achieve optimal sunlight exposure throughout the day. This means that photovoltaic panels on concrete blocks can efficiently utilize solar energy regardless of the roof's orientation. The most effective placement is towards the south, or alternatively southeast or southwest. Positioning 2 rows of blocks "back to back" creates space for east/west installation as well.

Installation of panels on blocks east/west

In conclusion, the choice between concrete blocks and metal/aluminum structures depends on the specific requirements and conditions of each project. However, if you are looking for a fast and simple installation of photovoltaic panels on a flat roof without the need for drilling, concrete blocks are the right choice. They provide stability, flexibility, and minimize the need for additional load on the roof.
