Standards and tools for fast project realization

Modern automation engineering is supported by standards and tools which allows for the simple combination of solution components. zenon offers powerful methods for the creation of templates with rich functional content and precisely adjustable interfaces. For an instance, the Solar PV SCADA Application Library in zenon supports the simple integration of devices like solar inverters, combiner boxes or metrology stations, based on the Modbus SunSpec standard. The SunSpec standard defines a stringent, yet simple to apply data model for solar PV related devices. Various device manufacturers support the standard. Integrating these devices in zenon therefore becomes very easy.


Ensuring peak performance

Economic operation is crucial in order to reach the desired return on investment. Operating your equipment effectively requires for constant monitoring of all involved assets, but also auxiliary data such as ambient and weather conditions. Generative capacity as well as generative targets need to be reliably balanced. The zenon Software Platform allows you to keep track of any performance aspect of your solar PV facility. Realtime data as well as long term historic archives and predicted values can be flexibly incorporated into an effective performance evaluation system. The storage of process data in open formats and the flexible exchange of archives via open interfaces or cloud-based storage media allows you to configure an adaptive solution. With that, performance management systems according to standards like IEC 61724 for Photovoltaic System Performance Monitoring can be easily built and constantly improved.

zenon allows you to compare data with KPIs, making your production more cost-effective
