Role of Weather Monitoring Station(WMS) in Solar Power Plant

Solar PV directly converts solar energy from Sun into electricity. This is a non-conventional and easy way to produce electricity. In the current era, larger PV plants are being set up by developers using solar PV panels.

In order to establish quality solar PV the government is also setting up policies in favor of renewable energy eg. wind, solar, etc. Further govt is also appointing/ forming authorized agencies to make guidelines for setting up a quality PV plant eg. IEC61724-1-2.

Weather Monitoring Station (WMS) is a mandatory Instrument to install in Solar PV power plants. after setting up the solar PV plant, we need a system for performance evaluation. here comes the role of the weather monitoring system in solar PV plants. the weather monitoring system has sensors like pyranometer, and anemometer for measuring various weather parameters. Plant owners use WMS to collect weather data to get many insights into the plant’s operation and possible ways to increase the plant’s output.

Mainly solar radiation data is the key factor affecting the PV system, but along with solar radiation, other weather parameters like ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, and rain are also important parameters in affecting the performance, without measuring and analyzing all these parameters data, any plant owner cannot take the right decision to make their plant more efficient.

In addition, ignoring these factors can harm the whole business. As we know, a small decline in plant efficiency can significantly affect the energy output and hence ROI.

Model of Automatic Weather station with all its components.

Structure of WMS:

A complete WMS is comprised of multiple weather sensors, which are shown in the below figures.

Components of Weather Station for the Automated Weather Observation System:
Anemometer– Measures wind direction and speed.

Thermometer – Measures atmospheric temperature.

Pyranometer – Measures solar radiation levels from the sun in watts per square meter (used to calculate ‘Evapotranspiration’, the rate at which water evaporates from the soil).

Hygrometer – Measures relative humidity using a percentage measure of water vapor in the air.

Barometer – Measures atmospheric pressure to predict precipitation and visibility.

Rain gauge – Measures liquid precipitation.

Datalogger: It is installed inside the enclosure box. it collects all sensor data and sends it to the client or meteoxperts cloud server.

Data monitoring software – Meteoxperts provides its own software so that customers can monitor data with the help of data tables and charts and use these data to improve the efficiency of their PV plants.

The benefits of WMS in a Solar Plant:

It helps you to collect and analyze weather data and predict them to get maximum output from your solar plant. The Photovoltaic (PV) system performance depends on both the quality of the system and the weather. As the weather varies the output of PV system changes.

The key factor to affect the PV system is solar radiation but along with solar radiation data, the weather parameters like ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, and rain are the other important factors affecting the performance. 

These are the list of benefits.

  • Efficiency improvement of plants, due to weather data monitoring.
  • Low-Maintenance required, due to regular supervision.
  • Risk management, due to early forecasting we can plan and reduce our risk.
  • WMShelps in planning out the maintenance activities
  • Damage Prevention- heavy wind loads at the site may cause damage with accurate wind speed and direction Users can take necessary steps to prevent damage and loss.
