SISCO total solar radiation sensor adopts a precision optical structure with a high-transmittance dome cover to improve solar energy measurement accuracy. The aluminum alloy housing provides excellent durability and protection, while the compact design supports reliable long-term operation.
Double Glass Dome and Thermopile Detection
- Features a double-layer glass structure for solar radiation transmission.
- Converts incident solar radiation into an electrical signal through thermopile detection.
- Uses a thermopile sensing design to measure incoming solar radiation.
Flexible Signal Output and Data Transmission
- Supports analog and digital output options, depending on the selected configuration.
- Uses MODBUS-RTU communication through the RS485 interface.
- Provides built-in or external transmission modules according to the output type.
- Accommodates different power supply requirements; the 0–20 mV version does not require an external power supply.
Applications
SISCO total solar radiation sensor is designed for accurate solar irradiance monitoring in photovoltaic systems, weather stations, environmental monitoring equipment, and research instruments.

Details
Q1: What is the difference between a total solar radiation sensor and a PAR sensor?
A1: A total solar radiation sensor measures overall solar irradiance across a wide spectral range, while a PAR sensor focuses only on photosynthetically active radiation. The two sensors are designed for different measurement purposes and wavelength ranges.
Q2: How should a solar radiation sensor be installed for accurate measurement?
A2: Proper installation requires a stable horizontal mounting position with an unobstructed view of the sky. Avoiding shadows, dust accumulation, and incorrect alignment helps maintain accurate solar radiation measurement.
Q3: How long can a total solar radiation sensor maintain measurement accuracy?
A3: With ±2%/year stability and a 2-year calibration period, a total solar radiation sensor can provide consistent measurement performance when properly installed and maintained.
Tips: How to maintain accurate measurements with a total solar radiation sensor?
- Install the sensor in an open area with an unobstructed view of the sky to avoid shadows or reflected light affecting measurement results.
- Keep the dome cover clean by removing dust, dirt, or water stains regularly to maintain proper light transmission.
- Ensure correct horizontal alignment during installation to improve measurement accuracy and reduce angle-related errors.
- Check calibration periodically according to operating conditions to maintain long-term measurement reliability.
- Protect the cable and connection points from moisture or mechanical damage when used in outdoor environments.
