Guide for PV systems on the roof

Guide: Fall Protection Photovoltaic (PV)-System

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

Even if the connection isn’t obvious at first glance, solar system installers and PV installation companies can acquire significantly more new customers with a partner who is a certified and professional manufacturer of fall protection systems for PV installations on roofs. The reason why is very simple: They are able to cover the subject of safety in the very first meeting with the customer, thereby relieving their potential clients of a large amount of research work.


Subsequent installation of a fall protection system for PV installations on the roof

It is never too late to make the right decisions and implement them! This means that even operators of PV installations on the roof should consider whether the subsequent upgrade of their solar power plant with a professional and certified fall protection system is feasible and sensible.


360° solutions as a guarantee for success

Solar system installers capable of including a safety solution with their PV systems hold a clear edge over the competition. You can find out why this is the case in the following article.

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.

All starts and ends with the full documentation of all tasks on the fall protection system – this is the only way to keep it permanently functional and to save lives in an emergency.

For you personally and also for companies, maintenance is very important, because such defects – often hidden – can destabilise the safety system as a whole. In extreme cases, this results in the fall protection system no longer being capable of withstanding the forces which arise during accidents. Consequences can be serious – not only for those directly affected and their families, but also for the operator of the PV system. Ignoring for a moment the possibility of seriously injured employees and related time off work, severe penalties and compensation payments also threaten in the event of negligence. 

So always remember: The servicing and inspection of fall protection systems for PV installations on a pitched or flat roof not only makes sense – it is a mandatory legal requirement. In most cases, the safety system must be subject to a thorough inspection once per year by an appropriately certified person. And this applies throughout the lifetime of the system. This also applies to personal protective equipment, lanyards, and single anchor points for the PV system. All cable and rail sliders too must be inspected and maintained every year as standard.

Attention: Fall protection systems used in the chemical industry or for indoor swimming pools are often exposed to severe stresses, such as chemical vapours, etc. For this reason, the inspection intervals should be shorter, especially in this range of applications.

In the INNOTECH training programme, the subjects of servicing and inspection of fall protection for PV installations on a roof are therefore dealt with in depth.

4 reasons for professional planning and installation of PV systems

During the installation of the PV system and its associated fall protection, it must be ensured that everything is correctly fastened and documented. This is important for the following 4 reasons: 

  • The system must be documented in writing and with photos, otherwise it is not permitted to use the system.


  • In the event of an emergency, lives can be saved only if the fall protection system has been professionally planned, installed, and documented.


  • Only in this case are you on the safe side in terms of the law. 


  • And only this way do you save yourself from unpleasant and often expensive surprises when the first inspection date looms one year after the system’s installation.


Correct servicing and inspection 

Ideally, you should conclude a servicing contract for your solar power plant and the associated fall protection system(duration generally 3 years) – best of all with the same certified solar technician or installer who installed everything on your roof. This not only saves time, but you also obtain everything from a single source. In addition, you can be sure that your solar technician always knows exactly what needs to be inspected.

Ensure from the very start that during the installation there is full documentation of the components, anchor points, posts, and connections on the substructure, by means of photographs, and that a comprehensive dowel log is created. If this is not done, then in extreme cases it may not be possible to perform servicing or inspection. The consequence of this would be that access to the PV system would be forbidden. In some cases, the fall protection system would then have to be dismounted and reinstalled. You can clearly see: If documentation is poor or even completely absent during installation, then high costs may arise subsequently.

Digital documentation from INNOTECH

With our web app INNO|doc, you, your solar technicians and installers can conveniently manage all your projects and customers by means of a single tool. Full documentation of the installation is important for being able to service the systems later on. In addition, INNO|doc sends e-mail reminders completely automatically for the legally required annual inspection. As well as that, the finalised documentation can be generated directly from the program – including all project-relevant details, such as photos, certificates, product descriptions, etc. And with INNO|doc every subsequent inspection and service can be performed very quickly without excessive effort, because all data is accessible at the press of a button. 


The inspection in detail

Inspection and servicing can be performed either by an installer/solar technician certified by INNOTECH, or by TÜV, a certified engineer of your choice, or another expert. However, even before this person accesses the system on the roof, the inspecting body will review all product descriptions and the documentation in detail.  


Checklist for servicing/inspection of a lifeline system:

  • Is the roof sealing damaged or corroded?


  • Do visible components of the fastenings display deformation or signs of corrosion, and are all threaded joints secured or tightly seated?


  • Visual inspection of strands of stainless steel cable


  • Is deformation of the intermediate bracket visible? Are the weld seams and all threaded joints in good condition?


  • Inspection of the structure and weld seams of the corner and end fastenings


  • Check of wedge wraparounds, indicator clamps, cable pre-tension, and welding points (crevice corrosion) of the end locks


  • Inspection of threaded joints and slide gap of sliders


  • Check whether an original INNOTECH carabiner is being used


  • Check of system functionality

Please ensure that the inspection and servicing tasks on the fall protection system for your PV installation on the roof are documented in full detail by means of logs and photos. This is the only way to demonstrate later that at the time of inspection the safety solution was in perfect order and therefore legally compliant. This is important for staying on the safe side in terms of the law. When an installer or solar technician is on your roof to inspect the fall protection system, use the opportunity to have servicing and cleaning of the solar installation itself performed.

This is essential for trouble-free, maximum performance of the solar panels. Our partner installers have the know-how to perform all these tasks themselves at the same time! Unfortunately, practical experience often shows that, out of laziness, the inspection and servicing of the safety system are neglected or even completely omitted. However, as the operator of a solar installation on a roof, you need to be aware that these regular checks are essential for the correct functioning of the fall protection system.

Without these elementary components of your safety concept, your feeling of safety will be an illusion! And, from the viewpoint of your insurance company, in the event of an emergency this can cause insurance benefits to be held back or not even awarded in the first place. Compare this with your car! It too must undergo a roadworthiness test at regular intervals to be allowed on the public highway. Here too, the consequences can be very unpleasant if you drive the car after its certification has expired and you are possibly involved in an accident.

The most frequent defects are

Fasteners unsuitable for the respective substructure are often used during installation of the fall protection system, or there is confusion regarding the correct fastening sets. This means that safety is no longer ensured. Unfortunately, time and again it occurs that the safety solution was incorrectly or insufficiently documented. In addition, at such an exposed location as a roof, loose mounts or corrosion of individual parts and components can naturally arise, and if these are not dealt with, they can become safety risks. 

If your fall protection system displays such defects, then access to the PV equipment would be temporarily forbidden. On the basis of the photo documentation we create the individual parts list for potential repair tasks, in order that your installer or solar technician can create a precisely tailored proposal for you. All defects are then remedied, so that your fall protection system is operational again as soon as possible, and above all safe. In an emergency (see above) the fall protection system must be completely dismantled and rebuilt from new.

You should therefore have your fall protection system inspected and serviced regularly, thus securing you the numerous resulting benefits. This means that you are always protected, not just in terms of safety and functionality of the safety solution, but also under the law. In addition, from the outset smaller defects are prevented from becoming larger (andtherefore more expensive) problems. 



The safety of your fall protection system is always only as good as the professionalism of the installation and the regularity of the inspection and servicing tasks. This all starts and ends with the full documentation of all tasks on the fall protection system – this is the only way to keep it permanently functional and to save lives in an emergency. This also helps you to protect against expensive and unpleasant surprises.
