Select the output, supply and mounting scope together
The reviewed Class C documents support the performance values below. Output, supply, cable, mounting and calibration deliverables remain order-specific.
- The reviewed instrument classification is ISO 9060:2018 Class C, with a 0-2000 W/m² range and 300-3200 nm spectral response.
- Sensitivity is 7-14 µV/(W/m²). Non-linearity is below ±3%, response time is no more than 60 seconds to 95%, and annual stability is below ±3% per year.
- Performance is expressed through the Class C component specifications rather than one generic accuracy number.

How to choose
- Confirm that ISO 9060:2018 Class C performance is appropriate for the PV, weather, agricultural or environmental measurement objective.
- Select one output that matches the logger or RTU: passive 0-20 mV, 4-20 mA, 0-5 V, RS485 Modbus RTU or SDI-12.
- Match the supply to the selected output. Passive millivolt needs no external power; powered variants use the supply stated for that ordered configuration.
- Define whether the sensor is mounted horizontally or in the plane of array, then review levelling, shading, horizon obstruction and cleaning access.

Compatible with
- Passive millivolt data loggers with sensitivity-based scaling for the selected sensor
- 4-20 mA or 0-5 V analogue inputs on the ordered powered-output variant
- RS485 Modbus RTU masters or SDI-12 loggers on the corresponding ordered variant
- Weather-station, PV monitoring and agricultural RTUs with suitable sampling and averaging logic
Typical package
- ISO 9060:2018 Class C thermopile pyranometer
- One ordered output configuration: passive 0-20 mV, 4-20 mA, 0-5 V, RS485 Modbus RTU or SDI-12
- Matching logger, RTU or analogue acquisition input with the required scaling and averaging
- Horizontal or plane-of-array mounting and levelling hardware confirmed for the site
- Selected cable length, surge protection, field power and enclosure where required
- Calibration-document scope, inspection plan and two-year recalibration interval recorded for the project
Applications
Use this Class C thermopile pyranometer to measure global solar irradiance from 0 to 2000 W/m² at PV, weather and agricultural monitoring sites. The reviewed family covers passive millivolt and several powered-output variants, but each ordered unit uses one selected output and its matching supply. Mounting plane, shading, cable, logger scaling and calibration documentation are fixed in the quotation rather than assumed from the family name.
- PV plant reference irradiance and performance-ratio input
- Automatic weather-station global solar-radiation measurement
- Agricultural evapotranspiration and irrigation-support datasets
- Solar-resource assessment and environmental monitoring
- Remote irradiance logging through a selected RTU, logger or acquisition gateway
What to include in your quote request

Frequently asked questions
What does Class C mean for this pyranometer?
The reviewed instrument is classified as ISO 9060:2018 Class C. Selection should use the published response, non-linearity, directional-response, temperature-effect and stability components instead of reducing performance to one unsupported generic accuracy number.
Which output should I choose?
Match the output to the site logger or RTU. Choose passive 0-20 mV for a compatible low-level input, 4-20 mA or 0-5 V for analogue acquisition, RS485 Modbus RTU for a serial master, or SDI-12 for a compatible environmental logger. One configuration is selected when ordering.
Does every output use the same power supply?
No. The passive 0-20 mV configuration needs no external supply. The powered variants use 5 VDC or 12-24 VDC depending on the selected output, so the output and supply must be quoted together.
How should the pyranometer be mounted?
Use a rigid, level and unobstructed location for global horizontal irradiance, or a reviewed plane-of-array bracket for tilted measurements. Record nearby shading, horizon obstructions, cable route, cleaning access and surge exposure before ordering.
What calibration documentation is included?
The reviewed calibration basis is ISO 9847 and the recommended recalibration interval is two years. The exact report, certificate or traceability documentation included with the order must be written into the quotation.
What should I provide when requesting a quote for the Class C Pyranometer for Solar Radiation Monitoring?
Application, measurement objective and required instrument class; Horizontal or plane-of-array mounting and site coordinates; Selected output and connected logger / RTU input; Sampling, averaging and reporting interval
Where can I compare available model options?
Open the Agriculture & Weather Hardware Catalog linked on this page. It lists audited SG-coded selections; the ordered configuration is confirmed in the quotation.
Will it work with my existing system?
Compatibility is reviewed against your field signals, protocols and upstream platform. Typical pairings include Passive millivolt data loggers with sensitivity-based scaling for the selected sensor, 4-20 mA or 0-5 V analogue inputs on the ordered powered-output variant, RS485 Modbus RTU masters or SDI-12 loggers on the corresponding ordered variant.
