.The SMP12 is a high quality pyranometer designed for measuring solar irradiance on a plane surface (radiant flux, W/m²), which results from combination of the direct solar radiation and the diffuse sky radiation. The measurement can be made horizontally for Global Horizontal Irradiance (GHI) or tilted for Global Tilted Irradiance (GTI). The SMP12 instrument is designed to measure and report solar irradiance, sensor body temperature, internal humidity and tilt angle from horizontal. The SMP12 can also be used to create an albedometer to measure surface reflectance where one SMP12 is facing the ground and another SMP12 is facing the sky.
All SMP’s have the RS485 Modbus RTU interface, very low power requirements and are supplied with comprehensive, traceable, calibration certificates. Calibrations are traceable to the World Radiometric Reference (WRR) in Davos Switzerland and are performed in accordance with ISO 9847, Annex A.3 ‘Calibration of Field Pyranometers by comparison to a Reference Pyranometer’.s and are supplied with comprehensive, traceable, calibration certificates.

Field Data Logger Options
The Meteon 2.0 is a significantly more advanced and versatile data logger than the Meteon, particularly for users working with modern “Smart” Kipp & Zonen pyranometers. It can accept up to 5 Smart pyranometers and one analogue pyranometer, plus one Modbus temperature and a pulse input for kWh values. The Meteon 2.0 can log up to 380,000 sets of min, max and average values. This logger is ideal for those needing to monitor multiple parameters (irradiance, temperature, energy) in PV applications.
If you require a permanent solar panel efficiency monitoring system, please contact us directly to discuss your requirements. We can provide bespoke tailored systems to fit any requirements with loggers suitable for transmitting data via Mobile network, Wi-Fi, Ethernet or even a satellite connection.
