STI Solar-Technologie-International GmbH

More than 20 years of experience as well as continuous research and development have been put in our high-performance collectors. Our own industrial production ensures the extremely high quality criteria of the collectors.

A constant quality standard at the highest level is guaranteed by a variety of measures of quality assurance as well as continuous monitoring throughout the production process.

Thanks to the latest absorption technology with proven ultrasonic welding and vacuum coating maximum revenues can be achieved with our solar collectors.

Besides quality and capacity environmental protection is ensured during development and production. Environmental protection means an efficient energy input throughout the production, short transport routes for ecological supply of raw materials and the use of non-toxic, recyclable material.

The competent know-how in the field of collector manufacture guarantees that all aspects from construction to quality control are taken into account during the production process.

Our high-performance flat plate collectors of the FKA series offer our customers many technical advantages. Our developments reach back to 20 years of experiences in the manufacturing of solar thermal panels. Beside the sign of quality 'Made in Germany' we offer our customers as well:

Universal collectors – one system for all types of installation: You are looking for a collector for roof-mounted installation? Or do you rather prefer roff-integrated installation? Either one is possible with our FKA and even more: we do offer wall console as well as bottom console installation.

Extensive accessories are being offered - from hydraulics to assembling material.

New materials offer a high potential of savings up to 20 % compared to full-sopper collectors - absorber with absorber plate and absorber tube made of aluminum stand up with the same performance and lower costs.

We have a wide range of products so you have a wide choice: the FKA series alone has a choice of 36 different varieties - in addition we can provide you with the solar thermal panel FINO, patented Drain Back systems and a photovoltaic-module matching our collectors.
