PD IEC TS 63019:2019

What is PD IEC TS 63019 – Photovoltaic power system information model about?  

PD IEC TS 63019 is an international standard that covers essential aspects of photovoltaic power systems. 

PD IEC TS 63019 provides a framework from which the availability metrics of a PVPS can be derived and reported.  

PD IEC TS 63019 describes how data are categorized and defines generic information categories to which time can be assigned for a PVPS considering internal and external conditions based on a fraction of time, system health, and condition by specifying the following: 

• Generic information categories of a PVPS considering availability and production. 
• Information category priority to discriminate between concurrent categories. 
• Entry and exit point for each information category to allocate designation of time. 

The PVPS comprises all photovoltaic (PV) modules, inverters, DC and AC collection systems, grid interconnection equipment, the site, its infrastructure, and all functional service elements. 

Note: Determining the method of information acquisition and specifying exactly how other undefined, time-based availability metrics shall be calculated is out of the scope of PD IEC TS 63019. 

Who is PD IEC TS 63019– Photovoltaic power system information model for?  

PD IEC TS 63019 on photovoltaic power systems information model is for: 

• Designers of photovoltaic panels/ modules and PV components 
• Manufacturers and suppliers of photovoltaic panels/ modules and PV components 
• Engineer/procure/construction companies 

Why should you use PD IEC TS 63019– Photovoltaic power system information model?  

PV power systems can vary in size from small rooftop or portable systems to massive utility-scale generation plants. An information model facilitates how the unavailability of time of components, subsystems, and systems, as well as the lost power and other capabilities, affect the PVPS. 

PD IEC TS 63019 identifies external and internal elements related to the capability, health, and condition of components, subsystems, and the system itself, in addition to production, plant operation, and asset management, which also benefit from a defined set of terms. This is achieved by providing an information model specifying how (PVPS) time designations shall be assigned by information categories.  

PD IEC TS 63019 on the photovoltaic power systems information model intends to exchange information on capability and energy-related data in great detail to form a nucleus for separate information, that is needed by stakeholders as different stakeholders will have different needs.
