From PV to BESS – the next stage for the energy transition

With the roof-mounted PV system installed in August 2025, the company has already reached a significant milestone. It has been supplying Green electricity for thermal management solutions, strengthens self-sufficiency and at the same time forms the technical basis for intelligent energy system integration.

Even during the initial project presentation, Managing Director Holger Kiebel announced that battery storage would be the logical next step to further increase energy efficiency and specifically manage peak loads. This very step is now being concretely prepared.

Impulse through Expert Webinars: Decision for BESS Concept

The impetus for the detailed project planning was provided by the Webinars from CUBE CONCEPTS on the topic of industrial battery storage systems. Participants Dieter Hehl and Albrecht Manz used the events to analyze technological, economic, and regulatory aspects of modern storage solutions.

The result was clear: a battery storage system can not only make PV surpluses usable in an efficient way, but also unlock additional economic potential – for example, through peak load shaving, grid fee optimization, or, in the future, participation in flexibility markets.

The Contracting Model as a Strategic Advantage

The planned implementation will follow the proven Contracting approach. This model makes it possible to integrate a BESS, including an EMS, without any upfront investment costs, while also benefiting from predictable electricity costs and professional operation. For TMS, this means:

• no capital commitment
• maximum planning certainty
• Reduction in electricity costs
• immediate CO₂ reduction effect
• Technological future-proofing

Step 3 on the path to climate-neutral production

The battery storage system represents the third building block of a clearly structured sustainability strategy at Thermal Management Solutions DE Oberboihingen GmbH. After initial implementation of efficiency and optimization measures, as well as compensation projects in operations, followed by the in-house generation of electricity through a photovoltaic system, the energy system is now being flexibly expanded through the use of a storage system.

This is making the Oberboihingen site an increasingly prominent example of industrial decarbonization in practice. As a manufacturer of high-quality thermostat and temperature control technology under the WAHLER brand, the company combines technological precision with sustainable action – while simultaneously strengthening its competitiveness in a changing energy market.

Transformation consistently thought through

With the planned BESS integration, Thermal Management Solutions is consistently continuing its course: moving from individual efficiency measures towards a holistic energy system. The project exemplifies how industrial companies can actively shape transformation – economically viable, technologically sound, and strategically long-term.

970,640 kWh of green electricity annually for Purem Rakovník

The facility will have an area of 4,760 m² take and with 2,438 Modules equipped. The expected annual production 970,640 kWh electricity covers a large part of the energy demand directly on-site. Around 87 % of the energy generated uses Purme immediately on site, only 126.169 kWh flow into the public grid. Thus, the project not only contributes to energy efficiency but also to independence from external electricity procurement.

500 tons of CO₂ savings

Particularly impressive are the effects on climate protection. The photovoltaic system avoids around 494.971 kilograms of CO₂ emissions – that's almost 500 tons. This will in the future 15% of total production at the site is climate-neutral enables.

Purem Rakovník as another building block for climate neutrality

The commitment of Purem Rakovník is part of an overarching strategy of Purem by Eberspächer. How the European operations will be made climate-neutral step by step. CUBE CONCEPTS was also allowed to, prior to this Work in Dresden with a 2 MWp photovoltaic system equip. With the new project in Rakovník, this path continues consistently. And it shows how partnership and technological competence lead to sustainable success.

Contract signing in Rakovník

The partners met in person in Rakovník to sign the contract: Michal Zechovský and Ivana Lacková represented Purem Rakovník, Vit Hlavacek represented CUBE CONCEPTS, and Miroslav Calda was on site as a representative of the implementing company, ATLANTIS. During this event, not only was a contract signed, but the foundation was also laid for a joint Vision project. The planned photovoltaic system symbolizes a partnership that prioritizes sustainability, innovation, and responsibility—paving the way for a climate-friendly future.

Our New Project Marketing: Making Sustainability Visible

With the commissioning of the PV system, we also celebrated another building block for our new project marketing. The CUBE-CONCEPTS approach: We not only support our customers in the planning, financing, and realization of photovoltaic systems, but also in communicating their commitment, respectively in the Photovoltaic Marketing.

These include, among others:

• Public Relations and Media WorkCreation of drone footage, videos, interviews, and background coordination.
• Inaugural Events during or after the plant's commissioning – planned and organized jointly with our customers.
• Symbolic Moments like the handover of a sustainability certificate, which reinforces the message internally and externally.

With this advanced approach, we ensure that our customers not only benefit from clean energy, but also have the opportunity to make their investment in the future visible – to employees, business partners, customers, and the public. And this applies to the regional press, the respective trade press, or nationwide and Europe-wide, if desired.

Positive Resonance & Media Coverage

As with our previous inauguration events, TMS also showed that the communication concept is working: The company expressed great satisfaction with the event's proceedings and was particularly pleased with the positive coverage in the regional press. This significantly amplified the project's impact once again and underscored the value of our joint project marketing. Furthermore, the event offered an opportunity to make new contacts and deepen existing relationships – added value from which both our client and we benefit.

The inauguration of the PV system at TMS once again demonstrates the importance of connecting technical implementation with targeted communication. Our joint approach makes the energy transition not only measurable but also visible and tangible. For TMS, the project meant not only another step towards climate neutrality but also a strengthening of its own market position – and this is precisely where we see the aspiration of our project marketing: to create results that have an impact beyond pure electricity generation..

Clean energy has been flowing from the roofs of Pfefferkorn in Simmern since the end of September 2022. The new 749-kWp PV system was implemented together with CUBE CONCEPTS and has been reliably supplying low-cost solar power ever since. A good 3,700 square meters of 2,204 solar modules were installed on the production halls in the weeks beforehand.

An important contribution to environmental protection

"This is the next logical step for our environment," says a delighted Ralf Gabler, Managing Director of Pfefferkorn. "We can use around 450,000 kWh directly in our buildings and also feed around 210,000 kWh into the public grid. We are thus making an important contribution to environmental protection," says Gabler. The photovoltaic system alone now saves the company 350,000 kg of CO₂ every year.

Pfefferkorn relies on the latest technologies

The Hunsrück-based industrial company is aware of its responsibility towards the environment and has already converted parts of its company fleet to e-cars. E-charging stations installed on the company premises. In order to further reduce CO₂ emissions and the consumption of energy and resources Peppercorn also relies on the latest technologies and consistently replaces old machines with new, efficient systems.

Environmentally friendly energy generation for the future

"A photovoltaic system is the logical consequence of our efforts to make a contribution to environmental protection and we are delighted to be able to play our part in environmentally friendly energy generation," explained the Pfefferkorn management when the PV roof system was put into operation.

• • Photovoltaic system with 414.96 kWp completed on the roof surfaces

• • 1092 solar modules on 2032 m²

• • Electricity production 403,766 kWh/year and CO₂ savings 189,721 kg/year

• • Further plants at locations in planning

 

More and more companies are switching to an autonomous, clean energy supply using their own wind, water and, above all, photovoltaic systems. Although not immediately autonomous, Matthias Ellinger (PA/FCM), Head of Facility Management at Syntegon in Crailsheim, opted for a power supply at the site that also takes the environment into account. Following last year's regional heating concept, a photovoltaic system has now been installed on the roof of building 120. 

Photovoltaic system as a win-win solution

Last fall, FCM and HSE jointly considered whether a PV system would make sense and looked for a suitable provider. "We found CUBE CONCEPTS, from whom we didn't buy the photovoltaic system outright, but rented it for 20 years," says Matthias. The power supply directly on our own premises is a win-win situation for us and Cube Concepts. Matthias explains: "We get cheap, clean electricity and CUBE CONCEPTS doesn't have to find another area for their PV system, which they would also have had to pay for." This is how the Photovoltaic system on the roof building 120 in Crailsheim, which was inaugurated in the second quarter of the financial year. Our purchasing and legal departments got the contract off the ground. "The great thing is that from now on we don't have to hope for clear sunshine, as the system can also absorb solar energy when the sky is overcast," explains Matthias. With around 400,000 kWh per year, 95 to 99 percent of which is fed into our plant, it will now produce around 9 percent of our electricity consumption at the site.

 

"The photovoltaic system is a clear sign of environmental protection"

Matthias from Syntegon in Crailsheim

 

Reduced carbon footprint and electricity costs thanks to new photovoltaic system

"Thanks to the Photovoltaic system even more carbon dioxide can be saved at the site, which will also reduce the syntegon-wide carbon footprint." The FCM and HSE team is celebrating even more successes. "We have the complete CO₂ annual target for 2022 with the help of the annex realized, which also benefits the Syntegon 2025 goals." Matthias is proud of the team and the positive impact the construction has had. "Of course, we will also continue to drive forward and implement further points in the direction of environmental protection."

Photovoltaic systems are also to be built on other roofs at the site in the future. However, some roofs need to be renovated first. The planned new buildings were planned from the outset with roofs that are suitable for PV systems. "This will allow us to expand the system in the future," says Matthias. 

Christian Bartels, Head of Engineering CUBE CONCEPTS: "With an occupied roof area of around 2000 square meters and more than 1000 modules, the system produces more than 400 KWp per year and thus makes a valuable and sustainable contribution for our customer. This is how companies can operate sustainably."

In Neustadt an der Donau kommt zukünftig noch nachhaltiger und emissionsfrei erzeugter Solarstrom hinzu, geplant und realisiert von CUBE CONCEPTS, the full-service partner for renewable energies and photovoltaics. With this, Yanfeng and CUBE CONCEPTS are leading the way to resource-efficient production and contributing to the reduction of CO₂ emissions with its PV system.

1.180.000 kWh aus Solarenergie

 

Die neue Photovoltaikanlage wurde bereits in Betrieb genommen und liefert rund 1.180.000 kWh kWh Strom im Jahr. Sieben Monate hat die erste Projektphase insgesamt gedauert. Baubeginn war Ende 2021, die Fertigstellung musste dann aber Anfang des 2022 aufgrund des Schnees kurzzeitig unterbrochen werden. Der zweite Bauabschnitt der PV-Anlage konnte im April 2024 in Betrieb genommen werden. Nun ist die neue Solaranlage offiziell abgenommen, in Betrieb und liefert zuverlässige Solarenergie.

95 % of solar energy is used for direct consumption

Insgesamt 3.100 Solarmodule wurden auf dem Dach der Werkshallen installiert, die die Sonnenstrahlen in elektrischen Strom umwandeln. Durch acht Wechselrichter wird der erzeugte Gleichstrom dann zu Wechselstrom verarbeitet – und somit direkt für den Einsatz im Werk von Yanfeng nutzbar gemacht. Über 95 Prozent der erzeugten Solarenergie werden direkt im Werk verbraucht. Besteht im Werk weniger Bedarf für die Einspeisung der Solarenergie, wird diese ins lokale Stromnetz der Stadtwerke Neustadt eingespeist. Rund 413 Tonnen Kohlendioxid werden im Jahr mit Hilfe der neuen Anlage eingespart.

Goal: Climate neutrality by 2030

„By switching to climate-neutral solar energy production, we can carry out our manufacturing processes in a more environmentally friendly and resource-conserving way,“ explains Gunnar Büchter, Executive Director Procurement & Strategy at Yanfeng in Europe. „Energy and emission savings at our locations are an important measure for achieving the self-imposed goals of our sustainability strategy and our ambition to produce climate-neutrally in our plants by 2030.“

A study by the BMWi confirms that electricity costs account for around 70 percent of total energy costs in industry. In addition, companies are increasingly being asked to achieve CO₂-neutral production across the entire supply chain. "From an economic point of view, it is therefore profitable to use as much electricity from renewable energies as possible. Solar power allows you to permanently reduce your costs, increase your efficiency and therefore remain attractive to existing and potential customers." The company will also take over the operation, maintenance and servicing of the system for the entire duration of the contract. With the new photovoltaic system, Yanfeng is achieving a pioneering milestone in the transition to climate-neutral energy production at the Neustadt site.
