Workstation4u – Powered by Solarbayer

Workstation4u is a brand of Solarbayer GmbH and stands for high-quality workstations, business PCs, servers and IT hardware. The company Solarbayer is a manufacturer and system provider of wood heating systems, thermal solar 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 field of IT hardware over many years. We have gained experience ourselves in the areas of CAD engineering, fluid/energy and radiation simulation as well as geodata calculation. For tackling these demanding tasks we rely on current enterprise-class IT hardware. To keep the high costs 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 is why a few years ago we decided to build a second business division for the sale of professional workstations and servers, to give you the opportunity to acquire high-performance hardware at affordable prices. With our large storage area of over 16,000 m² and a mature logistics system, we ensure fast and uncomplicated delivery. We have thousands of different workstations, desktop PCs, servers and notebooks in stock to handle even larger IT projects.

By purchasing and selling refurbished IT hardware we also make a significant contribution to conserving our environmental resources. Thus the Workstation4u business field ideally complements our primary business area of renewable energies.
