Once the process moves onto the roof, the main focus is on the high requirements with regard to quality. The comprehensive RAL-certification regulates everything down to the details. The company's internal system of controls has no gaps. Every installation team is managed by an electrical expert who works with skilled specialists. Construction management and higher construction management are the next levels. They are responsible for carrying out the predefined controls and acceptances. At the end, the final, comprehensive acceptance provides the ultimate assurance that the system is totally functional, in line with the state of the art, and that it runs without any problems.

One department deals solely with the development of its own system components. Internal engineers and technicians design detailed solutions tailored to the needs of individual clients and implement these with partners from the industry. This allows an optimal, long-term and secure solution for the client, in which compromises would have had to have been made in conventional systems. As before, “Made in Germany” quality remains a guarantee for an assured return.
