Influence of weather station and solar radiation monitoring on photovoltaic power station

Photovoltaic weather station is a weather station designed for photovoltaic power generation control. It monitors key factors such as solar panel surface temperature, total solar radiation, total solar radiation inclination, wind speed and direction, air temperature and humidity, and quantitatively outputs photovoltaic power generation meteorological environmental data. , Photoelectric conversion efficiency value, total radiation, provide real-time accurate data for photovoltaic power generation control.

It supports a variety of communication methods and power supply methods. Users can quickly change and expand data acquisition and processing methods and observation elements by selecting different types of sensors. installation method. Greatly facilitates user use and site maintenance.

Photovoltaic weather station product introduction:

Photovoltaic weather stations are mainly used to measure radiation (direct radiation, scattered radiation, inclination radiation, TBQ total radiation, simple total radiation, ultraviolet radiation sensor, net total radiation sensor) illuminance sensor, patch temperature (component temperature), five meteorological parameters ( It is mainly used in photovoltaic power stations and other environments.

Since weather conditions directly affect the power generation of photovoltaic power plants, the core parameters of photovoltaic power plant performance evaluation are inseparable from accurate weather station data and solar irradiance data.

Weather station sensors play an important role in photovoltaic power plant monitoring systems. Accurate meteorological measured data is the key to tracking, evaluating and controlling photovoltaic power plant performance parameters. Therefore, each photovoltaic power plant monitoring system requires a set of automatic weather stations and several different types of The solar pyranometer is used to calculate the core evaluation indicators of photovoltaic power plants.

So let's talk about the impact of weather stations and solar radiation monitoring on the entire life cycle in detail:

(1) The application of weather stations and solar radiation in the whole life cycle of photovoltaics, from resource assessment of power station site selection, real-time monitoring of power stations, forecast of power generation of power stations, power generation assessment, operation and maintenance management and transaction management, all require high precision and accuracy. Supported by stable meteorological and solar radiation data.

(2) The influence of high precision solar radiation on the cost of electricity and quality assurance.

(3) The influence of solar radiation accuracy on power prediction accuracy (power station production capacity).

In summary, it is necessary to use mid-to-high-end weather stations and solar radiation equipment and replace the low-quality meteorological and solar radiation equipment of the original photovoltaic power station.
