This ultimate fall protection guide will help you to achieve a safe PV system on the roof. In the following, we summarise the danger areas on the roof, the liability issue and the safety solutions in a compact way. In addition, you will learn how you can generate more turnover as a solar installer.


Elektro Scherer puts its trust in the TAURUS rail system from INNOTECH

In its practical implementation, the roof installation of PV systems together with their associated fall protection repeatedly creates specific challenges. In the case of Elektro Scherer, a TAURUS rail system from INNOTECH was attached directly to the K2 substructure of the solar power plant.


How roof surfaces can be optimally used for the planned PV installation

With regard to PV installations on roofs, the question of competition for area often arises. This refers to competition between various types of use for the available area. The reason is that in principle all PV system operators want to free up the maximum possible amount of space for their solar power plant.


Why should you, as PV installers, also offer the fall protection system?

We invited experts to a discussion on the subject of fall protection for PV systems on flat and pitched roofs. In this blog post we go into the most frequently asked questions related to this topic.


Individual or collective protection? Which system is used when for PV installations on a roof?

While dangers like break-throughs or an increased fall risk close to the roof edge lurk on a flat roof, on a pitched roof the inclination itself is the greatest challenge. Discover in the following article how you can professionally protect your maintenance and cleaning staff.


A professional safety concept for PV installations protects the wallet and the nerves

As a solar system installer, you naturally know every detail of the legal safety provisions relating to PV systems on a roof. In contrast, your clients may well be entering completely new territory which probably raises a number of additional questions. It is therefore all the more important from the outset to integrate the subject of safety into the planning of the PV system, and to create a substantiated and professional safety concept.


Successful solar system installers are those who offer PV fall protection at the same time

Solar system installers who, in addition to the optimally appropriate PV systems, can also provide the best possible fall protection, not only have a better image than their competitors – they can also use this to create increased turnover.


Safety increases business for solar system installers as full service providers

PV systems on the roof have been booming for quite some time. No wonder, because having your own solar power plant on the roof not only gives you much more independence in terms of energy supply, but also makes a significant contribution to the energy transition as a whole. If you also focus on the issue of safety on the roof, then as a solar installer you can leave the competition behind. In this article, you will discover how you can achieve this.

Supporting multiple PV customers simultaneously can often become a huge challenge

Not only private households, but also businesses and companies, are relying increasingly on generating their own solar energy. The presently escalating energy prices will hasten this trend even further. For solar system installers, this creates enormous potential for winning new orders. It can then very easily happen that multiple projects or construction sites have to be managed simultaneously. And that creates a number of challenges.


Work on a PV system on a roof

Installing one’s own PV system on a roof makes sense for a number of reasons. So that it always provides the best possible performance, workers regularly have to access the solar power plant in order to perform servicing and cleaning tasks. Who is responsible or liable for the consequences of accidents?


PV systems on a roof – consider all danger areas, in order to protect against falls effectively

The circumstances and conditions of every single order for a PV system on a roof must always be analysed very closely, in order to implement the correct safety precautions. Solar system installers who recognise all risks and can at the same time also propose the appropriate professional and certified solution to their customers have the opportunity to position themselves as a responsible absolute expert in their area. In the medium and long term, this also has a positive effect on the sales performance of solar system installers.


6 tips which help solar system installers to gain increased turnover from their PV installations on roofs

The right fall protection creates more space for the PV system

Here is an example from practice. ADREX relies on its proven one-stop-shop principle, in order to largely relieve its customers of all tasks related to their own roof-mounted solar power plants. This obviously also includes the selection and installation of a professional fall protection system for the PV installation.


Correct servicing and inspection of your PV fall protection system protects you from many problems

The fall protection for your PV system on a roof is 100% safe only if it is also inspected regularly for signs of potential wear and tear, damage, or corrosion, and for loose mounts. Discover what matters.


The professional way to install a fall protection system for your PV system on the roof

The detailed planning of the fall protection system for your PV system on the roof is followed by what is probably the most tantalising moment of the endeavour to make your solar power plant as safe and efficient as possible: the installation; the project is finally taking concrete shape. Discover what matters in the process.


The installation of a fall protection system for your PV system on the roof requires a certain amount of expertise!

The same rules that apply in all other areas of life and work also hold true in the area of fall protection systems for PV systems installed on a roof: Solid initial and further training are of pivotal importance, especially when it comes to the correct installation and proper servicing / cleaning of the system and its individual solar panels.


The aspects to focus on when planning a fall protection system for the PV system on your roof

The goal to harvest as much power as possible from your own solar power plant therefore hinges on the ability to maximise the utilisation of the roof surface, while securing the trouble-free operation of the solar power plant for the long term. This requires a comprehensive plan which factors in all details and also includes a professional system that protects against falls from a height.

5 tips relating to your PV system on the roof

How to save time and money. Installing a photovoltaic system on your own roof is always a good idea, because in this way a previously completely unused surface is availed of for the sustainable production of electricity for your household or company. But so that this success story really comes into being, as early as the planning phase of your PV system you should also create a professional safety concept, or get one created.


Professional fall protection for your PV system on pitched roofs

Installation tasks on the photovoltaic system, as well as its servicing and cleaning, represent a particular challenge. An selection of possible security solutions including advantages can be discovered in the following article. In addition, the topic of access to the PV system on the pitched roof is also covered.


Fall protection photovoltaics

Not all roofs are the same. In the same way that roof forms differ greatly, the dangers concealed during installation and servicing and cleaning tasks on PV systems are just as variable. For this reason, we present solutions for all cases here.

The advantages of such a measure are immediately apparent: A sound safety solution on top of the roof will ensure absolute legal certainty in an emergency. The solution will furthermore allow for the risk-free cleaning and servicing of the solar panels, keeping them in peak performance condition and preserving their ability to produce a maximum amount of electricity. Here are a few rules of thumb that will suggest whether such an upgrade is possible or indeed advisable: 

  • The PV system is exclusively secured by single anchor points – a type of fastening that is expressly advised against in the planning documents issued by the AUVA (Austrian Workers' Compensation Board), the DGUV (German Social Accident Insurance) and the SUVA (Swiss National Accident Insurance Organization).


  • But, even scenarios where the placement of the PV panels on the roof does not provide enough room for a fall protection system with class 2 equipment (cable or rail system) will allow for a professional upgrade with, for instance, a BARRIER system made by INNOTECH. 

Even after installation is already complete, you as a solar system installer can demonstrate your professionalism and sense of responsibility to your customers by recommending that they expand their PV installation by a certified fall protection system. And, it will be our pleasure to advise and assist you in this regard by sharing our expertise in safety solutions for PV installations on the roof and our extensive portfolio of various safety systems!

Solutions that allow for effortless retrofitting of PV installations on the roof

There is a wide variety of safety solutions that can be fitted on PV installations on the roof. All of them have their pros and cons. The list below will illustrate not only which fall protection systems are available but also the applications for which they can be used:


1. Superimposed load lifeline systems

  • VARIO-45: This universal point is installed in a snap and suited perfectly for roof pitch angles of up to 5°. What is more: as it is designed for installation without roof penetration, there is no need to open the roof cladding, preventing the creation of cold bridges.

    Use: End, corner and intermediate point in the AIO lifeline system and single anchor point for 1 person (UNI-EAP-10-25).


  • QUAD-30-300: This post for green roofs is an excellent choice for green or gravel flat roofs. This system is equally distinguished by its simple installation without roof penetration. Moreover, the QUAD-30-300 is attached / held in place only by the weight of the green roof structure.

    Use: Intermediate point in the AIO lifeline system, rail system bracket and single anchor point for 1 person (UNI-EAP-10-25).


The downside of these solutions: They take up a great deal of space and are more costly than other versions. 

The advantage: There is no need to open the roof cladding.



2. Installation on metal roofs

  • SYST-01: This robust system roof clamp from INNOTECH is exceptionally stable and versatile. Its sliding screw placement allows for optimum adjustment to each specific profile width. Its installation does not require roof penetration and is relatively quick as some elements have been pre-assembled.

    Use: End, corner and intermediate point in the AIO lifeline system, rail system bracket and single anchor point for 3 persons (UNI-EAP-10-25).



  • SDH-INDUSTRY-31: The robust safety roof hook is ideally suited as a variable support for all crimp heights.

    Use: Anchor point and safety roof hook.


  • SAND-01: This universal point for trapezoidal sheeting is architecturally unobtrusive and allows for flexible and rapid installation thanks to its universal base plate. 

    Use: End, corner and intermediate point in the AIO lifeline system, rail system bracket and single anchor point for 3 persons (UNI-EAP-10-25).


3. Installation on PV substructure 

  • This type of installation integrates the fall protection systems into the PV system and thus takes up no additional space on the roof. The lifeline system AIO and the rail system TAURUS from INNOTECH are installed directly on the PV substructure. Better yet, the installation of the fall protection systems AIO and TAURAS requires no roof penetration and causes no shadowing of the solar panels.

In which cases is a subsequent installation difficult?

There are, of course, situations or use cases where the subsequent installation of a professional fall protection system is difficult or even impossible. However, it cannot hurt in most cases to evaluate the current safety solution and improve it if necessary. Never forget: When emergency strikes, human lives are at stake – and, in the worst case, claims for damages or pain and suffering or even penalties for the operator on the grounds of gross negligence.  


The problem of “lack of space”

There are situations where the PV installation on the room takes up the entire space and leaves only little room for a fall protection system. In that case, it may be necessary to remove some PV modules to secure the roof accordingly. This will, of course, result in a reduction of the surface area available for the solar power plant / the generation of electricity. Notwithstanding, the decision to remove panels may improve efficiency in the medium and long term, as it will allow for the safe performance of servicing and cleaning whenever necessary and, thereby, the maximum output of the panels at all times. These products from INNOTECH are suited perfectly for this type of scenario:  


On a flat roof:

  • STA-10: Offering extreme stability, this universal post is suitable for nearly all types of substructures and perfect as a end/corner post for the cable and rail systems made by INNOTECH.


  • QUAD-11: This post can be used both as a single anchor point and as an intermediate post as part of the AIO lifeline system. It is suitable for every type of substructure.

Another option is to install a guardrail system. The downside is, however, that this system will cast shadows on the modules.  


On a pitched roof:

  • STA-10 with BEF-203: This fastening set is primarily attached on wood or pitched roofs/wooden rafters such as those found on farms.


  • SDH-31: This safety roof hook can be ideally adapted to any conditions on site and requires only modestly dimensioned wood.



Practice has shown that many existing PV systems on the roof are insufficiently secured against falls. This is why it is always a good idea to revisit and, if necessary, optimise the safety situation even after installation of the systems is complete. Safety can be improved with a wide variety of available and very professional solutions – even in difficult situations. Never forget one thing: The roof ranks among the most dangerous workplaces of all.

And you, as the operator of a PV installation on the roof, are responsible for the safety of all members of the workforce who carry out servicing and cleaning work in that danger area.
