The affordable custom-made alternative to build yourself
ALUSTECK® offers you great flexibility in the planning and implementation of your flat roof solar module mounting project. You can expand your solar module mounting with the functions you need and adapt it to the respective conditions at the installation site.
The mounting system for solar modules is particularly suitable because it can be adapted to any PV panel size and the tilt angle for alignment can be freely determined. Thanks to the individual self-build design of the construction, subsequent modifications can also be made. The aluminum construction also promises high durability for your solar module mounting.
Das System ermöglicht ganz einfach eine Solarmodul Halterung für das Flachdach selber zu bauen. Es eignet sich besonders für Flachdächer wie Garage, Haus, Carport, Gartenhaus, Schuppen etc.. Aber auch für Balkonkraftwerke oder ebenerdige Flächen in Garten, Hof oder auf der Terrasse eigent sich das System.
The system makes it very easy to build a solar module mounting for flat roofs yourself. It is particularly suitable for flat roofs such as garages, houses, carports, garden sheds, sheds, etc. But the system is also suitable for balcony power plants or ground-level areas in the garden, yard, or on the terrace.
The common fastening on flat roofs is done using ballast or direct screwing onto the roof surface. Heavy curb stones are used as ground anchors for weighting on the roof. The stability of the solar module mounting for flat roofs can also be increased by wind deflector plates on the open sides or just by a rear panel cladding.
Through an individual and well-thought-out design, the yield can be optimally utilized throughout the year by a controlled, improved angle.
The aluminum framework is durable, and the construction remains easy to handle. Another advantage of the flat roof mounting system made of triangular supports for your photovoltaic system lies in its quick and cost-effective assembly.

UV Resistance of the Solar Module Mount: Since there is limited UV resistance in connectors, we recommend additional sealing with UV protective lacquer. For this reason, an additional aluminum safety rail was integrated into the design at the node point of the load-bearing articulated connector and an internal steel core in the Right Angle connector. UV protective lacquer also provides optimal additional protection against potentially damaging solar radiation!

Tip:Note on the optimal orientation of your solar / PV system
The optimal orientation for a solar module in Germany is towards the south with a tilt of 30 degrees; however, deviations usually result in only minor yield reductions. Orientation towards the south is optimal because solar radiation is highest there. However, the greater the deviation from due south, the lower the tilt angle of the modules should be.
The optimal tilt of the solar module is achieved when sunlight strikes it perpendicularly. This is the case when there is a 90-degree angle. However, since the sun changes its position throughout the day and over the year, a fixed solar module results in an angle between 30 and 35 degrees over the annual average.

Building instructions - Building a solar module mount for a flat roof
This solar module mounting bracket for a flat roof for DIY is made of aluminum. Therefore, you never have to worry about rust. The following bracket is designed for horizontal installation on a flat roof, but can also serve as a ground mount. Before you can start with the actual construction of the bracket, you must first order the material in our online shop. To create a bill of materials with all individual dimensions, you can ideally use our Solar Module Mounting Bracket Configurator.
A detailed A-Z assembly instruction for the complete assembly, including ground anchors and the installation of the solar module, is available in our free PDF Solar Module Mount Construction Plan.

Structure of the construction with example dimensions (Panel size 1,500 – 1,800 mm)
This sketch shows the very simple construction of the module mounting bracket. After you have assembled everything, you can mount your solar module, for example, on the garage or carport roof. However, before the elevation, the roof statics should also be investigated and checked. Weight distribution, load-bearing capacity (ballasting of the fastening, increased snow load) and shear forces from wind loads should be considered here.
Important: Observe assembly instructions
Securing each plug-in connector to the aluminium profiles with self-tapping screws.
Junction point for stiffening against high wind loads.
Sturdy angle connector with an internal steel core and thread.
Anchoring the mounting frame with 2 concrete slabs of 50 x 50 x 5 cm (total weight 56 kg) to secure it against high wind loads.
Alternative to anchoring the mounting frame: 1 kerbstone of 100 x 25 x 6 cm (total weight 35 kg) to secure it against high wind loads.
This selection of fixing materials for securely and firmly anchoring the ground anchors is absolutely necessary to ensure adequate structural stability.

Photovoltaics on the flat roof - tilting or mounting flat?
A mounting system is an erected support structure for solar modules, also known as a solar module bracket. The attachment of the solar modules to this support structure allows the PV panels to be optimally aligned with the sunlight. These usually consist either of a metal frame, as in this aluminum version, or of simple rails that are firmly screwed, clamped, and/or secured to the roof with heavy materials, e.g., concrete slabs.
There are many advantages that speak for a solar module mounting system. Firstly, it offers higher efficiency for the PV panels due to the sun-facing incline. Another advantage, in contrast to flat-lying photovoltaic systems which are very susceptible to dirt, arises from an inclination of approx. 10°, as the so-called self-cleaning effect through rain and snow sets in.

FAQ: Build your own flat-roof solar panel mount
Yes, with the ALUSTECK® plug-in system you can configure the mount exactly to your desired dimensions and adapt it flexibly.
The mounts are made of durable aluminium profiles that are corrosion-resistant, stable and particularly light. Aluminium is also weatherproof and ideal for long-term use on the roof.
Yes, there are ballasted mounting systems that require no roof penetration. Alternatively, screw or adhesive systems can be used. This keeps the roof membrane intact, which is particularly advantageous on flat roofs with waterproofing membranes.
The optimal tilt angle for solar panels in Germany is between 30° and 40° in order to make the best use of solar energy. Too shallow an angle reduces efficiency, while too steep an angle can reduce output in summer.
The mount must safely bear snow loads, wind forces and the panels' own weight. A structural calculation should therefore be carried out before installation.
You can plan and order your individual mount directly via the ALUSTECK® online configurator. This gives you a tailor-made solution that fits your flat roof perfectly.
