JLP02 is a solar radiation sensor that is applied in general observations. It measures the solar radiation received by a plane surface from a 180
Introduction
o field of view angle. This quantity, expressed in W/m2
, is called “hemispherical” solar radiation. JLP02 pyranometer can be employed outdoors under the sun, as well as indoors with lamp-based solar simulators. Its orientation depends on the application and may be horizontal, tilted (for plane of array radiation) or inverted (for reflected radiation).
JLP02 pyranometer is a very good alternative to silicon cell (photodiode-based) pyranometers, which do not comply to the ISO 9060 standard.
Operation
Using JLP02 is easy. The pyranometer can be connected directly to commonly used data logging systems.
The irradiance in W/m2
is calculated by dividing the JLP02 output, a small voltage, by the sensitivity. This sensitivity is provided with JLP02 on its calibration certificate.
Uncertainty evaluation
The uncertainty of a measurement under outdoor conditions depends on many factors. Guidelines for uncertainty evaluation according to the “Guide to Expression of Uncertainty in Measurement” (GUM) can be found in our manuals. We provide spreadsheets to assist in the process of uncertainty evaluation of your measurement.

Use as sunshine duration sensor
WMO has approved the “pyranometric method” to calculate sunshine duration from pyranometer measurements in WMO-No. 8, Guide to Meteorological Instruments and Methods of Observation. This implies that JLP02 may be used, in combination with appropriate software, to estimate sunshine duration. This is much more cost-effective than using a dedicated sunshine duration sensor.
