KOSTAL Solar Terminal

The KOSTAL Solar Terminal is the central platform for all digital business processes at KOSTAL. From here, you can access all other central KOSTAL applications in just one click.

The KOSTAL Solar Terminal can be used by both plant operators (private and commercial) and business customers (installers and specialist dealers).

As a plant operator or business customer, you can register here. 

The following applications are available to plant operators (private and commercial):

The following applications are available to business customers (installers and specialist dealers):

• KOSTAL Solar online shop

More KOSTAL applications will follow and be added shortly.

The KOSTAL Solar Terminal first takes you to the home page where you will find the user-specific area and selected applications.

With the help of tiles, users can access all other KOSTAL applications centrally via the home page or menu. 

In addition, users can easily switch back and forth between the individual KOSTAL applications.

In the new KOSTAL Solar Terminal, you can conveniently handle all business and administrative processes yourself – in just a few clicks. You can also manage your own profile and enter, compare and edit data.

This gives you complete transparency and control over all information in the KOSTAL Solar Terminal. A rights and roles concept allows you to add other employees from your company as users to the KOSTAL Solar Terminal and assign them their own rights and roles.

One distinctive feature is that you access the KOSTAL Solar Terminal and all other applications with just one login (single sign-on).

With the new KOSTAL Solar Terminal and integrated single sign-on, you only have to log in once and then you can access all KOSTAL applications without any further action.

Single sign-on allows you to access all KOSTAL applications. This saves time and is secure and user-friendly. In addition, the new KOSTAL Solar Terminal with single sign-on facilitates mobile working from any location.
