Highlights of Sullex Weather Monitoring System:

  • Real-time and historical data enables comprehensive evaluation of system performance.
  • Compatible with Sullex IOT devices with simple configuration, hence reducing installation and maintenance costs.
  • Easy visualization of sensor data on Sullex Cloud Portal.
  • Calculate Power, Expected vs. Actual Power Output, Module Efficiency etc.
  • Immediate identification of defects and malfunctions in Solar PV systems.
  • Immediate anomaly detection prevents solar PV system to remain shut down for long period due to lack of sufficient information.
  • Data Storage in case of no internet availability.

Sullex Weather monitoring System has the following sensors:

The module temperature sensor is used by PV plant operators to know the temperature of the modules installed in the array. The module temperature sensor converts this reading into a voltage signal. This signal is sent back to the monitoring device.

As the system operator it’s important to know the systems’ performance. The module temperature sensor will help to enhance kWh performance by ensuring reliable access to the all necessary data.

Wind Speed Sensor is designed with rugged components stand up to hurricane‐force winds yet are sensitive to a light breeze. Includes sealed bearings for long life. The range and accuracy specifications have been verified in wind‐tunnel tests. In areas where icing of the anemometer is a problem, drip rings deflect water from the joint between moving parts.


The Solar Radiation Sensor, or solar pyranometer, measures global radiation, the sum at the point of measurement of both the direct and diffuse components of solar irradiance. The sensor’s transducer, which converts incident radiation to electrical current, is a silicon photodiode with wide spectral response. From the sensor’s output voltage, the console calculates and displays solar irradiance. It also integrates the irradiance values and displays total incident energy over a set period of time.

The outer shell shields the sensor body from thermal radiation and provides an airflow path for convection cooling of the body, minimizing heating of the sensor interior. It includes a cutoff ring for cosine response, a level indicator, and fins to aid in aligning the sensor with the sun’s rays. The space between the shield and the body also provides a runoff path for water, reducing the possibility of rain- or irrigation-water entrapment. The diffuser is welded to the body for a weather-tight seal; it provides an excellent cosine response. The transducer is a hermetically-sealed silicon photodiode with integrated amplifier. Spring-loaded mounting screws, in conjunction with the level indicator, enable rapid and accurate leveling of the sensor. Each sensor is calibrated against a secondary standard Pyranometer in natural daylight.

It is a naturally aspirated, 6-plate radiation shield. Its louvered construction allows air to pass freely through the shield, serving to keep the probe at ambient temperature. The shield’s white color reflects solar radiation.

The most effective passive shelter. Protects temperature sensor from solar radiation and other sources of radiated and reflected heat. Multi-plate construction for maximum airflow
