Workstation4u – Powered by Solarbayer

Workstation4u is a brand of Solarbayer GmbH and stands for high-quality workstations, business PCs, servers and IT hardware. Solarbayer is a manufacturer and system provider of wood heating systems, solar thermal systems, heat pumps and innovative storage systems.

With our own design, development and IT department, we have built up extensive and well-founded know-how in the area of ​​IT hardware over many years. We ourselves have experience in the areas of CAD engineering, fluid/energy and radiation simulation as well as geodata calculation. To handle these demanding tasks, we rely on the latest enterprise-class IT hardware. In order to keep the high costs of this within limits, we recognized early on that remanufactured and individually assembled hardware fully meets these requirements. From this position we can provide you with advice in finding and configuring the ideal hardware for you.

That's why we decided a few years ago to set up a second business branch selling professional workstations and servers in order to give you the opportunity to purchase high-performance hardware at affordable prices. We have over thousands of different workstations, desktop PCs, servers and notebooks in stock to be able to handle even larger IT projects.

By purchasing and selling remanufactured IT hardware, we also make a significant contribution to protecting our environmental resources. The Workstation4u business area therefore ideally complements our primary business area of ​​renewable energies.
