International Standard of Pyranometer Selection for PV Power Plant

Solar radiation measurement at PV power plant:

IEC Standard has a guideline for Pyranometer selection: IEC61724-1: Photovoltaic System performance

1. Part 1 : Monitoring

Monitoring system class required for each application:

IEC61724-1 Part1 Clause 4: Monitoring system classification

Class A / B monitoring system is recommended for utility scale solar power plant. Class A or Class B would be most appropriate for large PV systems, such as utility-scale and large commercial installations, while Class B or Class C would be most appropriate for small systems, such as smaller commercial and residential installations.

2. Measurement items required for each application

3. System size and quantity of Pyranometer

4. Required Pyranometer class

5. Required Pyranometer accessories (ventilation unit)
