SMP10 Pyranometer

The Kipp and Zonen SMP10 Pyranometer is a Class A  (secondary standard) pyranometer. Widely used in the solar energy sector for performance monitoring, the SMP10 is considered the industry standard for performance.

  • 5-year warranty
  • ISO 9060  spectrally flat Class A
  • Internal drying desiccant – very low maintenance
  • RS-485 Modbus output (also either V or A output)
  • Wide range of power options 5-20VDC



Kipp and Zonen SMP10 Pyranometer


In our opinion, the Kipp and Zonen SMP10 pyranometer is the flag ship pyranometer within the solar energy sector. The SMP10 offers exceptional performance, very easy installation, versatile output options with very low maintenance all without upsetting the accountants.

The Kipp and Zonen SMP10 Pyranometer is a Class A  (secondary standard) pyranometer that combines the sensor technology and smart interface from the CMP11 pyranometer with the low maintenance from the CMP10 Pyranometer. The accuracy of the measurement and the RS-485 Modbus serial communications means the SMP10 is perfect for any sized PV solar farm where full SCADA integration capabilities are needed.

Thermopile sensor

Widely used within the solar energy sector, the SMP10 provides high-quality data for feasibility studies and monitoring the photovoltaic performance of established solar projects. The SMP and CMP range of pyranometers utilise a thermopile sensor.  Thermopile sensors absorb a greater spectrum of solar radiation (than silicone sensors) and have a near-perfect cosine response. As a result, they are considered superior to silicon sensors.

The Kipp and Zonen SMP10 has an internal drying cartridge that will last for at least 10 years. This minimises maintenance significantly by reducing the requirement to replace the desiccant cartridge (as per the SMP11 Pyranometer). The drying cartridge is replaced as standard when the SMP10 is returned for re-calibration.

The interval for dome cleaning can be extended, and the quality of measurements maximized, by fitting SMP10 with the CVF4 ventilation unit.
