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 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.

Christoph Ortner

And: this is how you create a consciousness for this essential area with potential PV system operators. 


The most frequent sources of danger on a roof:

  • Roof edge – this must be made safe against falls


  • Skylights – the risk of a breakthrough exists here


  • Stumbling – such as exposed pipes, lightning protection, etc.


  • and: The statics of the roof must be tested in advance, because a PV system can be installed on a roof only if the statics are in order.


The most frequent access routes onto a roof: 

  • through the roof – e.g. through a skylight or a roof window


  • by means of ascent aids – ladders or scaffolding


  • through windows/doors in the facade of a higher connected building


Attention: As soon as the ascent aid is accessed, the users are positioned in the danger area. This also applies to windows as soon as they are open. It is therefore advisable in every case to consider very closely in advance where the ascent is to take place, and how this can be made as safe as possible.

New call-to-action

Project initiation and inspection of the property

At the outset it should be mentioned that, when inspecting or accessing the roof, every person must be protected by means of temporary fall protection. This means that all necessary safety precautions must have been taken by the time of the project initiation. As well as using PPE, skylights can for example be optimally secured using the EAP-MOBI system for the access period. This system can also act as a temporary anchor point. This also has the benefit that clients immediately get a good feeling, and feel themselves to be in safe and expert hands.

In addition, the confidence in the solar system installer will increase even further when he recognises all danger areas on the roof and discusses them with the client. If the partner whom you rely on is a certified and absolutely reliable manufacturer of fall protection for PV installations on a roof, you are also immediately able to offer a suitable safety concept in terms of the best possible fall protection for the respective solar power plant. This not only creates confidence, it also brings a significantly higher turnover volume per order. It is also a good time to emphasise the benefits of a professional, certified fall protection system.

Indeed, from experience we know that many operators of PV systems on a roof choose improvised safety solutions for their solar power plant, without however knowing how these actually react to the enormous loads from a fall in an emergency. This is where an illusion of safety can arise.[US1]  And this can work out expensive, much more so than a reliable, certified fall protection system perfectly adapted to the situation. 

Tip: Undergo an extensive training programme, such as the PPE training from INNOTECH, and also recommend this to your PV customers. The modules teach all details related to our fall protection systems. And they also go into detail about the illusion of safety.  



If, for example, access takes place via a window, the protection can be provided in the interior – using EAP-LOCK-11. This receptacle sleeve from INNOTECH is attached permanently to the building structure and covered with a protective cap when not in use, and is therefore completely inconspicuous. The best way to protect access via a ladder is to use vertical cable and rail systems. These include, for example, TAURUS VERTICAL and the VERT LIFELINE SYSTEMfrom INNOTECH. For every danger area, we offer the optimum protection against falls from a height. This is also a huge benefit for PV customers, because they can then compare all available systems, and then make a solid decision on the fall protection which best suits them. 

Info: Not all ladders are the same. In practice, a distinction is made between simple ladders and permanently installed ladders. Simple ladders are permitted only up to a height of 5 metres. Above this, permanently installed ladders with an appropriate safety solution – such as the VERT LIFELINE SYSTEM or the TAURUS VERTICAL – are mandatory. But the exit area of a ladder onto a roof must also be secured against falling. This is where the BARRIER ASCENT LADDER is a good option. You can see the importance of considering a project holistically!

New call-to-action

The transition

The transition from the ladder or the window to the roof is certainly one of the most dangerous moments, because the users are generally also carrying cleaning equipment or tools, and do not always have both hands free. Regardless whether the users climb onto the roof from the interior via a window, or from the exterior via a ladder, the first anchor points must be within comfortable reach, in order that the users can secure themselves appropriately, so as to get to the next anchor point.

For access from the exterior, the transition area can also be secured using a rail at the side, such as the BARRIER ASCENT LADDER, in order to make the exit from an ascent ladder onto the roof surface absolutely safe.

Tip: For the transition to a flat roof where the PV system is located, collective protection such as the BARRIER ASCENT LADDER is ideal for protecting against falls. 


On the roof

In terms of safety technology, the PV system on a roof is always a challenge, because numerous obstacles, such as chimneys, satellite dishes, skylights, air-conditioners, or other anchor points are located on the roof. And in addition, falls through the roof are increasingly frequent. However, professional safety solutions are available for all these challenges. That is why every detail always needs taking into account when selecting the appropriate fall protection or safety system for the PV installation on a roof – even as early as the planning stage.

Here, above all, the respective fall height is important, but so too are the ground plan of the building and the onsite climatic conditions, because in especially cold or rainy areas the dangers which threaten differ from those in warmer climes. It is also of decisive importance to always select the correct PPE (personal protective equipment) against falls, as well as the correct lanyards – PSA-BRAKE or PSA-STRING – and also the right harness for PPE - PSA-STRING-1-BASIC or PSA-STRING-1-COMFORT, so that all tasks on a roof can be performed in safety.

Attention: If a fall occurs, a canopy or garage also reduces the fall height. Consider this fact when selecting the safety solution and the use of the PPE. Here, the lanyard requires particular attention. This needs to be shortened to use the system only as a restraint system, rather than as a fall arrest system. 

New call-to-action

Also remember that tasks on the roof must always be carried out by two people. While one person performs the repairs or cleaning tasks, from within the protected area the second person must keep an eye on everything, and instigate appropriate measures in the event of an emergency. It is therefore advisable to order all PPE modules at least in duplicate. 


Long-term customer relations and increased turnover 

A holistic consideration of your projects, with a corresponding recommendation for professional and certified fall protection systems can do more than just bring you increased turnover. For solar system installers, it also opens the option to create very long-term customer relations, such as a maintenance contract for the fall protection system, which in any case by law must be inspected every year. 

Note: The facade is a further source of danger which may also be relevant in the case of PV systems. You will find all relevant details here.



Solar system installers who have a professional partner for fall protection systems can present themselves as highly expert and responsible providers of PV systems, because they simultaneously provide a safety solution. However, it is important here that all details of the respective order are taken into account, in order to neutralise all danger sources in the long term. PV system operators really appreciate this, because in this way they have absolute legal certainty and protect lives.
