How accurate is the FT-BGF11 large-scale photovoltaic environmental monitor?

Large-scale photovoltaic environmental monitoring instrument, that is, weather station, because the daily operation and maintenance of photovoltaic equipment are more sensitive to meteorological conditions, especially solar irradiance, temperature and visibility, as well as severe weather such as strong winds and lightning also have an important impact on photovoltaic power generation. Therefore, the photovoltaic industry needs the assistance of meteorological environmental monitoring instruments, strengthen meteorological monitoring and early warning services, and help the development of the photovoltaic industry. At present, Fengtu Technology has launched FT-BGF11 large-scale photovoltaic environmental monitoring instrument, its introduction is as follows:

FT-BGF11 large-scale photovoltaic environmental monitoring instrument is a meteorological environment monitoring system specially set for grid-connected photovoltaic power stations. The system follows the standard design. Real-time monitoring of ambient temperature, ambient humidity, wind speed, wind direction, atmospheric pressure, tilted total solar radiation, horizontal total solar radiation, horizontal direct solar radiation, horizontal scattered solar radiation, albedo radiation, backplane temperature, peak sunshine hours and other parameters. Stable performance, high detection accuracy, no need for human duty, can meet the needs of photovoltaic power stations for meteorological monitoring and early warning.

Design standards followed:
International Meteorological WMO organization meteorological observation standards
IEC (International Electrotechnical Commission) specification standards
GB/T 19964 "Technical Regulations for Photovoltaic power generation Access to Power System"
Q/GDW11000 "Code of Operation Information Exchange for grid-connected Dispatching of Photovoltaic Power Stations"

The efficiency of solar power generation is closely related to solar radiation, so solar radiation is a key monitoring object. In this regard, the solar radiation sensors used in the FT-BGF11 large-scale photovoltaic environment need to be calibrated for at least two years in accordance with the requirements of the National Meteorological Station on the "JJG 458-1996 total radiation meter" to ensure its accuracy. In addition, the on-site radiation data can be automatically calibrated and automatically corrected to further increase the accuracy. The direct radiation sensor and scattered radiation sensor are equipped with global adaptive fully automatic solar tracking, which can be used globally at latitudes less than 60° south and less than 60° north, and the temperature range is -40 to 60° C.
