Our Energy Systems division designs and installs energy-efficient system solutions for customers in industry, trade and commerce.
We can provide exactly the right solution for your premises, too. We have been designing and installing photovoltaic systems of all sizes for many years. On behalf of our industrial customers we construct rooftop installations from a roof area of 1,000 m². However, open spaces can also be used for the production of green electricity.
Make yourself independent of rising electricity prices and power providers - find out about the attractive and economical solutions our experts would like to introduce you to.
The advantages – benefit from photovoltaics on your company roof
Rooftop PV systems from SENS: individual, competent, independent
Today photovoltaic systems often generate electricity at more favourable conditions than electricity from the public grid. Once built, such a system will supply cheap electricity for more than 20 years - at predictable fixed costs. In many cases the complete own consumption of a business can be covered using a PV system. Surplus power can either be fed into the public grid or used to intercept peak loads by applying an intelligent energy concept.
However, your own rooftop system is often just the beginning here. In order to make energy available on a permanent basis, the excess electricity produced can also be temporarily stored thanks to a supplementary energy storage solution. With such an installation you will make a long-term investment in the future and contribute to environmental protection.
In 10 steps our experts will accompany you to your turnkey rooftop system. In the process we develop a customised solution, tailored to the individual requirements of your company. From a system size of approx. 90 kWp we also design your rooftop photovoltaic system.
A roof-mounted PV system in just 10 steps
Step 1: Non-binding enquiry by telephone or email
Have we aroused your interest in your own solar system? Then please contact us as a first step, so that we can check the requirements for your roof-mounted PV system. Describe to us briefly and without any specific form the general conditions of your project. Details of the roof area in question (age, alignment, etc.) are already very helpful at this point. A member of our sales team will contact you within 48 hours with an initial estimate.
Step 2: Checklist for outline planning
In order to be able to create an initial rough plan for you, we need some more information in the next step. A detailed checklist for this will also be provided by our sales representative within the first two days. The more information our planners already have at this point, the more detailed SENS can plan your system. The type of roof covering and any existing insulation as well as the location of the electrical connections are particularly important here. Once all the data is available, our experts can start planning. Of course we will accompany you in compiling the information.
Step 3: Project design with cost breakdown
In the third step, the SENS experts draw up a project design that is individually tailored to your situation. The concept consists of a non-binding offer including cost breakdown, system layout and electrical planning. Throughout the entire process it is important for us to remain in close contact with you. For this purpose, we provide you with a direct contact person from the sales team. This person will personally present the relevant design of the PV system to you in order to jointly agree on the optimum solution. You are also welcome to contact us at any time if you have any questions!
Step 4: On-site appointment for an individual consulation
In order to be able to implement the PV system, in the next step we need an on-site appointment to clarify the final technical issues. Are you in agreement with the presented solution, the costs and the commercial key data? Then the detailed planning can begin. Our experts will calculate the system statics, which must be approved in relation to the building before construction can begin. The following points are also clarified by our staff at this stage: a precise measurement of the roof, recording the electrical connection, identifying deposit and storage areas and clarifying if scaffolding is required. This does not mean any additional work for you. You only need to provide access to the roof areas and the utility room for the electricity connections. We take care of everything else!
Step 5: Detailed fine tuning incl. network compatibility check
Now we get down to the details! In order for you to be able to benefit from green electricity from your own production in the future, a network compatibility test is required when setting up a "decentralised feed-in unit", which must be submitted to the responsible network operator. Of course we provide the network compatibility test for our customers within the scope of our cooperation. From an effective inverter power of 135 kW upwards, the so-called system certification of your roof system is also mandatory. We coordinate your preferred partners for the marketing by a direct marketer of the surplus electricity fed into the grid (from 100 kWp) and the necessary technical requirements. Once we have all the information, the SENS team will prepare a binding offer for you.
Step 6: Approvals obtained, time to install the PV system
The results of the preceding detailed planning are incorporated into the final offer within one week. You will accordingly receive an offer for a PV system tailored to your individual requirements with all costs - as a turnkey solution! On request, our team will supplement a suitable battery solution for your own consumption or peak shaving. Have we fulfilled all your requirements? Then our SENS team looks forward to receiving your order! This can be done quickly and informally - just get in touch with your personal contact person.
Step 7: Installation & set-up of the PV system
In line with the coordinated construction schedule, in the 7th step the construction of the solar installation can begin. For this purpose, we coordinate directly with the responsible persons at your company regarding delivery, start of installation, etc. In doing so, we pay particular attention not to disrupt your normal business operations during the construction phase. As a guideline for the approximate construction time of the system, you can use the following rule of thumb: per 100 kWp installed capacity, a construction period of approximately one week can be expected. You can also obtain detailed information on the current progress from your contact person or our site manager on site.
Step 8: Acceptance & start-up of the energy solution
As soon as the installation of the roof system is finished, a complete functional test of the system is carried out. The acceptance test takes place together with a responsible person from your company, while the test results are documented by SENS. After the technical readiness for operation has been established, the initial start-up of the system generally takes place together with the acceptance test. In order to test the functionality, the installed generator must once have supplied power which is used outside the PV system.
Step 9: Instruction in the operation of your PV system
The instruction in the operation of your new PV system is generally carried out by our solar experts together with the initial commissioning. Here, the functions of the essential components are shown to you, the operation of the entire system is explained and relevant operating states and resulting procedures are described. From this point on, nothing stands in the way of you producing green electricity directly on your roof!
Step 10: Operation of the roof-mounted PV system
With the successful commissioning of the new solar roof system, your company is on the way to an energy-efficient future. If you wish, SENS will of course continue to support you: whether with the design and implementation of further PV systems, the installation of a supplementary energy storage solution or even electric charging options. STEAG Solar Energy Solutions can also cover the O&M processes for you. We will be happy to take care of the technical management and monitoring of your new PV roof system. Simply get in touch with your contact person for an overview of what the possibilities are!

Rooftop photovoltaic systems not only produce green electricity, but also generate extra income thanks to direct marketing with the market premium model.
Companies aspire to a green image. They can now play a pioneering role and equip the roofs of their buildings with solar systems to generate energy for their own consumption.
The existing charging stations for electric cars will soon no longer be sufficient. To avoid so-called load peaks, an improved charging infrastructure is needed.
PV systems are also subject to fire risks, but fortunately these risks are limited. Various measures can be taken to prevent a fire.
Supported by our solar experts, the Wassergewinnung Essen GmbH has entered into green electricity with photovoltaics.
Different types of charging technology can be distinguished for the charging of electric cars. In most cases a combination of normal and fast charging stations is the best choice.
