If you are unable to attend at the scheduled date and time, we make recordings available to all registrants for three business days after the event

This course will highlight how Plant Controls and Supervisory Control and Data Acquisition (SCADA) systems provide the critical capability to control, monitor, and analyze the performance of solar and solar combined with storage plants. Throughout the day and a half program, attendees will learn everything from PV plant and storage basics, functional requirements of the plants, and how these requirements are implemented in plant controls and SCADA systems.

All attendees will leave the class having a holistic understanding of the plant controls and SCADA systems that pertain to solar plants and solar plus storage plants. It will benefit you whether you’re an operator or a professional who needs a detailed understanding of operation, reliability, and stability of a PV and storage plant, or a sales professional who needs a better understanding of the system to better serve customers. The goal by the end of the course is to have all attendees develop a working familiarity with the key concepts related to this topic.
