With this range of services, SOLID is the only full-service provider for solar heating in the world.

The advantage of SOLID is that it does not produce its own collectors or components and therefore does not focus on selling its own products, but instead selects components that optimally meet the needs and requirements of its customers. For this reason, SOLID cooperates with several globally recognized manufacturers in the further development and design of their products. In cooperation with SOLID, significant increases in product efficiency have already been achieved on several occasions.

Research & Development:

Research and development is a fundamental part of SOLID's corporate structure and a key driver of successful innovation. Through good cooperation with, for example, universities or research institutes (theory) and industry (practice), SOLID exchanges experience and uses the resulting know-how in a targeted manner to apply it in new projects and products.
