Antrieb Solarfaltdach

dhp covers the entire value chain and controls all areas itself - even where external specialists provide support. We develop, manufacture and plan the solar folding roof projects at our own highly automated production site in Zizers/Graubünden, Switzerland.
We are certified according to ISO 9001 and ISO 14001.

Solarfaltdach - Projektmanagement


Project management & construction.

Our project managers, external specialists and the installation team work hand in hand and always in close exchange with the client. Cost estimates, tenders, procurement, cost control and scheduling: these are the disciplines in which we are experts. This is how we create solar folding roofs that please everyone – the client, our partners and ourselves.

Solarfaltdach - Monitoring & Services


Monitoring & service.

We monitor your system 24/7 via a specially developed control centre. The service contract also includes the initial intervention and the annual inspection. We are happy to offer services such as energy management and optimisation as well as detailed analyses and reporting on request.

Finanzierung Solarfaltdach



We offer solutions for financing your folding solar roof project. The project can be financed as contracting by us or third parties. In this case, you commit to purchasing electricity and can take over the system after a certain period of time if you wish. For projects outside Switzerland, instalment credits with a term of up to 10 years can be offered. We will be happy to support you in working out your financing solution.
