THERMO/SOLAR is the largest independent company producing solar thermal collectors in Europe. From 2015 the company supplies complete photovoltaic systems.

THERMO/SOLAR was established in 1992 as a joint venture of Slovak aluminium production plant ZSNP based in Ziar nad Hronom and German thermo|solar Energietechnik, that time the largest manufacturer of solar collectors in Germany. From the start the company benefited from more than 20 years of previous experience of its founders in the field of development and manufacturing of solar thermal collectors.

The joint venture has opened the door for the products made in Ziar nad Hronom to western Europe markets. This subsequently lead to increase of quality and fast production growth. The quality of solar collectors has been positively influenced by mutual exchange of “know-how” of both partners: High efficient selective absorbing layer – the contribution of Slovak partner, and progressive deep-drawn aluminium casing of a collector – the contribution of German side.

Production of innovated type of evacuated flat plate collector began in Ziar nad Hronom in 1997. Even in present time, this collector is the only product of this type in the world. The main advantage is its high efficiency at higher working temperatures, while requirin relatively low investment cost. Its design makes it suitable especially for production of industrial heat and space heating for buildings.

THERMO/SOLAR Ziar and its original founders have during their 45 years existence produced and sold hundreds of thousands solar thermal systems. These are used especially for water heating, combination of water, swimming pool and space heating, industrial heat production, as well as other special applications.

THERMO/SOLAR Ziar is permanently investing not only into research and development, but also to environment protection during the manufacturing process. This results in 100% regeneration of anodising and pigmenting solution in the galvanic line for the production of high selective conversion layer and installation of the technology for rinsing water purification.
