Pyranometer- Why to Measure Accurate Solar Irradiance ?
The Solar Radiation Sensor, or solar pyranometer, measures global radiation, the sum at the point of measurement of both the direct and diffuse components of solar irradiance.
In-plane irradiance received by the PV array is one of the most important and significant factors that directly impacts the PV Performance. Irradiance must be measured accurately to determine your optimal PV performance ratio.
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-
