PV profiles: The basic structure of the PV system

Photovoltaic profiles form the basic framework for the installation of photovoltaic systems. The mounting rails (also: solar rails or solar profiles or PV lightweight construction profiles) are used to securely attach the solar modules to the roof. It is therefore very important to initially use stable and durable PV profiles when installing a PV system.

At Alu-Verkauf.de we offer you high-quality PV profiles made of stable and corrosion-resistant aluminum. Our aluminum profiles are not only durable, but thanks to their low weight they can also be easily transported onto the roof and installed well. This makes them ideal as a basis for PV systems.

Why buy PV profiles from Alu-Verkauf.de:

• Robust profile with 1.5 mm wall thickness offers secure attachment even under difficult assembly conditions.
• Convenient installation thanks to the extra large groove, compatible with standard and easily available hammer head screws
• Less waste on site thanks to precise cutting – you only pay for the material you actually need Short delivery times
• daily shipping directly from warehouse/collection on site

Advantages of aluminum as a material for PV profiles

PV profiles are usually made of aluminum. This is due to the diverse, positive material properties of aluminum. Above all, due to its light weight and weather and corrosion resistance, aluminum is perfect for outdoor substructures, as is usually the case with solar or photovoltaic systems. This makes them particularly durable, which also increases sustainability, which is particularly important in this context. Other advantages of aluminum as a construction material include the following:

• Low density
• Can be formed hot and cold
• Easy to machine
• Cheap compared to steel
• Easy to cut, with little spark
• Recyclable

Due to its many advantages, aluminum is used as a construction material not only for photovoltaic modules or solar systems, but also in mechanical engineering, electrical engineering as well as vehicle and aircraft construction.

Find the PV rail in your desired size using the configurator from Alu-Verkauf.de

Once the planning of your photovoltaic system has been completed, the next step is to install the appropriate PV rails. The aluminum mounting profile forms the basis for installing the entire PV system and ensures that the solar profiles can be safely attached to the roof.

At Alu-Verkauf.de you have the opportunity to have your PV rails customized: To do this, select the desired dimensions (profile 40x40 mm) and the alloy in our configurator and specify the length of your mounting rail. We can supply aluminum mounting rails up to 6 meters long (equivalent to 6,000 mm).

By entering the desired data into the configurator, you will automatically receive a price preview for the desired item. Delivery information will be provided upon check-out. After ordering, the PV profiles are usually dispatched on the next working day.

The path to the right dimensions: planning the PV system

The installation of a photovoltaic system on the house roof needs to be carefully prepared and planned: In addition to the orientation and load-bearing capacity of the roof, other factors such as possible obstacles in the area must be taken into account. Once it has been clarified whether and in which area of the house roof a PV system can be installed, it is also important to find out which type of solar module is suitable, how many modules can be mounted on the roof and how the system can be wired.

Only when these aspects have been clarified should you start measuring and ordering the required mounting rails.

After installing the PV profiles: The electrical installation

If the PV profiles are attached to the roof and the respective clamps are locked (usually via a groove opening), the solar modules can be attached to the profiles.

The final step is the electrical installation of the system. For this purpose, direct current cables are laid, via which the solar modules are connected to an inverter, in which the electricity generated in the modules is converted into alternating current. This means that the electricity generated on the roof can be fed into the household power grid and consumed.

Only when you have received the appropriate approval for putting your system into operation can you have it registered and finally put it into operation.
