Solar panels on
flat roof fixing
You are looking for a solution to mount solar panels on a flat roof. For example, because your roof is not sturdy, or because you do not want to work with extra ballast. These options are available. Below you can read about suitable mounting systems and how the mounting of solar panels on a flat roof works.
Solar panel mounting on a slab and sloping roof
The type of roof – flat or sloping – determines the technique for mounting solar panels and requires a specific approach. Due to the position of the sun, it is important to place your solar panels at the correct angle.
Slanted roof
On a pitched roof, installation is easy, because the roof already has a fixed angle of inclination, usually between 15 and 45 degrees. This allows the panels to be fixed directly to the slope, which ensures a stable and safe installation. The natural angle of inclination also reduces the impact of wind, which further promotes the stability of the panels.
Flat roof
With a flat roof it is different. Here the ideal angle still has to be created to optimize the solar yield and minimize shadowing. This requires special mounting systems that are not necessary on sloping roofs, which means that considerably more weight is involved. Many flat roofs do not have the load-bearing capacity to support this extra weight, which can be an obstacle to the installation of solar panels. RABLE has a solution here solution found for.
Mounting options for a flat roof
There are various mounting methods for attaching solar panels to a flat roof. There are many systems where ballast is used to do the mounting. But this adds a lot of extra, unnecessary weight. This makes it impossible to mount solar panels on many flat roofs. A renovation is needed first.
The solution: RABLE's self-supporting mounting system
Our ballast-free and self-supporting mounting system is the solution to attach solar panels to flat roofs. Without expensive renovation of the roof. Our systems offer flexibility, are easy to install, and reduce the load on the roof. In addition, they offer waterproof protection and are particularly suitable for coastal areas and open terrain with strong winds.
Installing solar panels on a flat roof without ballast?
RABLE has designed a mounting system where no ballast is required. Installing solar panels on a flat roof without ballast offers an innovative solution to the disadvantages of traditional installations.
The RABLE system allows you to secure solar panels to all flat roofs with minimal mounting pointsThis creates a simple and durable installation. This way you avoid damage to your roof and can make optimal use of your available roof surface.

Our fastening systems can withstand extreme weather conditions without any problems, thanks to the corrosion resistance of Magnelis steel and aluminium.
Sustainability
By choosing these high-quality materials, you are investing in a solar energy system that will last a long time and continue to perform.
Reliable
RABLE's systems have all necessary certifications and are approved by both SCOPE12 and NEN standards.
Flat roof solar panel rules
When installing solar panels on a flat roof, there are a number of legal rules that you must take into account. In most cases, no permit is required, provided that the panels remain within 0,5 meters of the roof edge and do not protrude higher than 1 meter above the roof edge. In addition, the solar panels must be firmly attached to prevent them from coming loose in heavy gusts of wind. Check with your municipality whether additional rules apply to installing solar panels., especially if your roof is located in a protected city or village view.
Rable's mounting system complies with NEN1010. You can find the important pieces here.
Available subsidies
Subsidies such as the Investment subsidy for sustainable energy and energy conservation (ISDE) and various municipal incentive schemes offer financial support for individuals and companies who want to install solar panels. Subsidies make the installation more accessible and contribute to the return of the project.
If you choose RABLE, we will be happy to support you in applying for the right subsidies. This will save you time and ensure that you benefit optimally from the available advantages.
Rules for installing solar panels
The rules for solar panels on a flat roof
When installing solar panels on a flat roof, there are a number of legal rules that you must take into account. In most cases, no permit is required, provided that the panels remain within 0,5 meters of the roof edge and do not protrude higher than 1 meter above the roof edge. In addition, the solar panels must be firmly attached to prevent them from coming loose in heavy gusts of wind.
These rules apply to ensure the safety of the installation and to prevent possible damage. Check with your municipality whether additional rules apply to installing solar panels., especially if your roof is located in a protected city or village view.
In addition to the legal rules on placement, the load-bearing capacity of the roof must also be checked. The roof structure must be strong enough to carry the weight of the solar panels and the mounting system. This applies in particular to systems that work with ballast, which adds extra weight to the roof.
That is why it is essential to have a structural survey carried out before installing solar panels. This way you can be sure that your roof can withstand the weight of the installation, the wind load and any snowfall.
Frequently asked questions about mounting solar panels on a flat roof
What is the best position for solar panels on a flat roof: portrait or landscape?
We have designed our system in such a way that the panels are attached to our system in landscape. The 12,5 degree angle of inclination ensures optimum generation of sustainable energy.
How are solar panels mounted on a flat roof?
Our solar panels are mounted with roof anchors. We use up to 95% less roof anchors to keep the installation in place.
How do you attach solar panels to a flat roof without damaging the roof?
We have designed our own supporting structure that can be used on weak, flat roofs. At RABLE we use a unique self-supporting PV mounting system for flat roofs, which allows roofs with a load-bearing capacity of only 7 kg/m² to be used for PV installations, without structural modifications to the building. To keep the installation in place, minimal attachment points (roof anchors) are used.
What angle is best for solar panels on a flat roof?
The ideal angle of inclination for solar panels on a flat roof is usually between 10 and 15 degrees. This ensures optimum absorption of sunlight and prevents dirt from accumulating. That is why we have chosen an angle of inclination of 12,5 degrees.
Are solar panels on a flat roof less efficient than on a sloping roof?
Solar panels on a flat roof can be just as efficient as on a sloped roof, as long as they are installed at the right angle and direction to capture maximum sunlight.
Is it possible to use a roof attachment other than roof anchors?
This is possible, for this you can contact RABLE.
