360° plant engineering electrical engineering and lighting technology

With innovative technologies and the comprehensive expertise of our specialists, we develop and design all electrical engineering, lighting technology, control technology, and mechanics for new and existing systems. Our solutions are customer-specific and are completely adapted to the specific infrastructure and requirements:

New systems are designed for the future today and automated as required. System expansions and upgrades are reliably integrated into the existing environment. We precisely coordinate all interfaces to ensure that your systems function smoothly and trouble-free.

Lighting systems, especially sun simulation systems for test benches and test applications, are a key focus of our product range. With over 25 years of experience in the solar simulation industry, Mr. Riebl is one of the leading experts in his field. In management positions at well-known companies, he was responsible for all areas – from sales, planning, and design to development, project planning, and installation to commissioning and servicing of solar simulation and irradiation systems.
His innovative solutions have had a lasting impact on the industry and set new standards. Mr. Riebl now brings this comprehensive expertise to Nesys GmbH, which has been successfully active in the field of solar simulation since 2023. Together, we are shaping the future of solar simulation – efficiently, precisely, and sustainably. With their comprehensive expertise, our experts in plant engineering, electrical engineering, lighting technology, control technology, and mechanics support systems across all development stages and technologies.

The nesys modular system – more flexibility with modules

Our modular system solutions support you in the development of your processes. You benefit from maximum flexibility, simple expansion options and cost-efficient adaptation to individual requirements. The modular design is suitable for new systems and system expansions. The modules are optimally adapted to common vehicle sizes, requirements and test standards: Systems in modular design are faster to deliver, cheaper and can be flexibly adapted to different testing requirements. You save time and money and benefit from efficient processes.

Consulting and design for system modernization

For new test or process requirements, we adapt your electrotechnical or lighting system to current test requirements and standards while conserving resources. We make targeted use of the automation potential and increase operating and energy efficiency. Smart control systems and digital interfaces enable more precise control and seamless integration into existing structures. This keeps your system future-proof and efficient without unnecessary investment in completely new equipment.

We look forward to hearing from you

Frequently asked questions about our services

In which regions does nesys operate?

nesys is in use worldwide. Our systems and services are delivered and supported internationally. In many regions – e.g. in Europe, North America and Asia – we work with certified local partners to ensure fast response times and direct on-site service.

How long are the delivery times for nesys systems?

The delivery time for standard modular systems is usually around 10 weeks. For customized special systems, the time frame depends on the complexity, range of functions and technical requirements. nesys guarantees transparent project planning and close coordination with the customer throughout all project phases.

Does nesys also offer maintenance and service for external systems?

Yes – nesys offers maintenance, service and modernization not only for its own products, but also for solar simulation and special systems from other manufacturers. Our experienced specialists have in-depth know-how in the commissioning and support of commercially available systems from a wide range of manufacturers in the field of lighting technology and electrical engineering.

How individually can nesys respond to requirements?

Customization is our core business. At nesys, there are no standard solutions – we develop systems that fit the application, environment and budget exactly. Technical complexity is not an obstacle, but our daily routine.

How does a project with nesys GmbH work?

Our project structure is efficient and proven:
1. Project initiation: clarification of all technical and organizational requirements
2. Development of a solution concept: incl. functional description and visualization
3. Design & planning: completely in-house by our engineering team
4. Production & assembly: via our production partners and our own resources
5. Commissioning & training: on-site worldwide by our specialists
6. Long-term support: through maintenance contracts and short-term service calls

Does nesys operate in a security-related or military environment?

Yes, nesys also develops special systems for sensitive areas such as test systems or environmental simulation systems in accordance with MIL standards. The highest standards of quality, confidentiality and reliability apply here – requirements that we meet.
