JLP02 is a solar radiation sensor that is applied in most common solar radiation observati**. It complies with the second class specificati** of the ISO 9060 standard and the WMO Guide. JLP02 pyranometer is widely used in (agro-)meteorological applicati** and for PV system performance monitoring.

JLP02 is a solar radiation sensor that is applied in general observati**. 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 conditi** 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.
Suggested use
• general meteorlogical observati**
