Solar Radiation Sensor Pyra 300V

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 sunlight sensor must be installed at the same azimuth and tilt angle than the PV array.

Solar Radiation Sensor Mounting Guidelines

Follow these step-by-step instructions carefully to ensure accurate sensor leveling and cable security.

Initial Leveling: Using the bubble level on the sensor as a guide, adjust until perfectly leveled.
Radiation Sensor Height: The top must align slightly above the rim of the rain cone.
UV Sensor Height: Entire comb structure must remain visible above the cone rim.
Final Leveling: Do final leveling once ISS is installed in real position.
Cable Integrity: Ensure cables are straight without crimps.
Secure Cables: Tie cables firmly to avoid wind damage.
Final Test: Shade sensor – reading must change (function check).
