The new national standard has officially taken effect! How can wind speed and direction monitoring for photovoltaic power stations achieve compliance? Maritech propeller-type sensors provide the answe
On July 1, 2026, the photovoltaic industry reached a milestone moment – the official implementation of GB/T 20513.1-2025 "Photovoltaic system performance – Part 1: Monitoring." This standard replaces GB/T 20513-2006, adopts the IEC 61724-1:2021 international standard as equivalent, and comprehensively unifies the technical system for photovoltaic system performance monitoring.
What changes does the new standard bring?
The core of the standard can be summarized as "expanded dimensions, stricter accuracy, optimized methods, and enhanced compatibility." In terms of environmental parameters, in addition to conventional measurements such as module temperature, ambient temperature, air pressure, and humidity, wind speed and wind direction are explicitly included as mandatory environmental parameters for photovoltaic systems for the first time. This means that wind speed and direction sensors have now become "standard equipment" for grid-connected acceptance of photovoltaic power stations. Whether centralized or distributed photovoltaic power stations, all must be equipped with professional meteorological stations to comprehensively collect core parameters including irradiance, backsheet temperature, and wind field. Failure to meet these requirements or insufficient accuracy will directly affect grid-connected acceptance.
Why is wind speed and direction monitoring crucial for photovoltaic power stations?
Wind speed and direction data directly affect module ventilation, heat dissipation, and backsheet temperature, serving as the core data benchmark for power generation assessment, power forecasting, and operations and maintenance scheduling. When wind speeds reach dangerous thresholds, real-time data can assist O&M personnel in promptly determining whether equipment operating conditions remain safe, preventing strong winds from causing damage to power generation equipment.
