Our pyranometers ensure the highest accuracy in Irradiance  measurements and are suited to provide both-

·       Global  horizontal irradiance

·       Irradiance  on collector plane

Global Horizontal Irradiance (GHI) is important because it is  the parameter measured in weather and climate networks, derived from  satellite instruments and calculated with clear sky energy models.

A pyranometer tilted in the Plane of Array (POA) of the PV  modules measures the irradiance available to the cells and is used for  calculating energy yield and Performance Ratios. This is why you will often  see pyranometers in pairs, one horizontal and one tilted.

 The  pyranometers are equipped to provide-

·       Individually  optimised temperature compensation

·       Individually  measured directional response, with the test results provided

·       They  are designed for simple maintenance and have a wide range of accessories  available

·       To  offer you the best accuracy when in the field a new calculator is available  to provide you with the real-time uncertainty in your application

  Pyranometers are most  important part of our automated weather station. Logics PowerAMR Platform

  supports various reporting features and  analysis from pyranometer data-

 ·       Weather Module - The system supports all makes of weather sensors such as  pyranometer, Module temperature sensor, ambient temperature and humidity  sensors , wind speed sensors ,wind direction sensors, Rain gauge etc.

·       PR analysis- In  depth analysis of plant performance with reference to weather sensor data and  includes PR analysis, PR curve and PR logs of the day, irradiation v/s power  curves, irradiation v/s module temperature curves, GHI v/s tilted irradiation  etc.

·       Plant Performance- helps to check complete health analysis of the solar plant at  one glance, also includes key parameters like solar insolation, peak  generation, expected energy, specific power, specific yield etc.

·       Irradiation v/s power curves - Power production graph comparing with the solar irradiation  during the da (available within the same axis for comparison)

·       Graphical representation of solar irradiation and active power in the same time axis.

 There are various classification of Pyranometers according to ISO  9060:1990 (E), namely –

1)      Secondary Standard  Pyranometers

2)      Second Class Pyranometers

3)      First Class Pyranometers

Typical Pyranometer comparison is as listed below-
