LPPYRA-Lite is a very small and light pyranometer based on an accurate thermopile sensor for ordinary monitoring of small PV systems. Its exceptionally compact dimensions ease the installation and the integration into any application.
At the same time, being a Class C Spectrally Flat according to ISO 9060:2018, it guarantees the accuracy, reliability and precision of the measurements, in compliance with the reference standards. Each sensor is characterised by its own calibration factor, indicated on the body of the pyranometer. Specifically designed for direct tilted installation on PV panel plane, it does not require any levelling device, but for installations where horizontal positioning is needed, an optional fixing base with integrated levelling device is also available.
