For Rapid Support

Avoid expensive retrofitting from the outset - depending on the installation site and the applied PV plant components, our project engineering team plans all the measurement points that require monitoring.

We provide the complete configuration of necessary technology, data communication and data banks, in addition to the adjustment of the power plant control system to meet the requirements of the local public utility company.

Extend the lifecycle of your PV power plant and the warranty of your installed components! Our maintenance team inspects, repairs and updates your power plant on a continuous basis.

Our highly-trained control room team, with its extensive experience in renewable energies, provides permanent management, monitoring, documentation and analysis of your PV power plant.

skytron PV plant monitoring and control solutions are comparatively unique in the young solar market. For a good introduction and to cover the basics of our monitoring concept, we offer regular training workshops at our head office in Berlin.

So as to be able to react quickly and competently to your requests in the case of an emergency, we provide a number of ways for you to quickly reach the right contact person
