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 construction, development and EDP department, we have built up extensive and at the same time well-founded know-how in the field of IT hardware over many years. So we have gained experience ourselves in the areas of CAD engineering, liquid/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 for this within limits, we recognized early on that refurbished and individually assembled hardware fully meets these requirements. From this position we can advise you to find and configure the ideal hardware for you.

That's why we decided a few years ago to set up a second line of business with the sale of professional workstations and servers in order to give you the opportunity to purchase high-performance hardware at affordable prices. We have thousands of different workstations, desktop PCs, servers and notebooks in stock so that we can also handle larger IT projects.

With the purchase and sale of refurbished IT hardware, we also make a significant contribution to protecting our environmental resources. The Workstation4u business area thus ideally complements our primary business area of ​​renewable energies.
