Introduction
Welcome to the next level in solar radiation monitoring!
The all-digital sun[e] pyranometer offers the highest accuracy and highest data availability: using new
Recirculating Ventilation and Heating (RVH
TM
) technology, sun[e] outperforms all pyranometers
equipped with traditional ventilation systems. sun[e] is the ideal instrument for use in PV system
performance monitoring and meteorological networks.
The sun[e] measures the solar radiation received by a plane surface, in W/m
2
, from a 180
o
field of
view angle. The sun[e] is an ISO 9060 secondary standard pyranometer. It is employed where the
highest measurement accuracy is required. The sun[e] offers several advantages over competing
pyranometers:
•
Heated for best data availability: new RVH
TM
technology outperforms traditional pyranometer
ventilation
•
The first pyranometer compliant in its standard configuration with the requirements for Class A
monitoring systems of the new IEC 61724-1:2017 standard
•
Low cost of ownership: remote diagnostics and supported by an efficient worldwide calibration and
service organisation
•
The right paperwork: instruments are supplied with the ISO 9060 required test certificates

Recirculating ventilation and heating between the inner- and outer dome is much more
power-efficient than traditional ventilation systems.
