Solution
Solar radiation measurement
Pyranometers, pyrheliometers and sun trackers for meteorology, climate research and solar parks. We build stations that measure global, direct and diffuse radiation – and keep them clean, calibrated and running.
))
What we measure
From a single pyranometer to complete stations on sun trackers.
Global radiation
Total solar radiation on a horizontal surface, measured with a pyranometer.
Direct radiation
Radiation straight from the solar disc, measured with a pyrheliometer on a sun tracker.
Diffuse radiation
Radiation from the sky, measured with a pyranometer shaded by the tracker’s shading ball.
Plane-of-array radiation
A pyranometer tilted like the solar panels, to follow up a solar park.
Sunshine duration
Calculated from the direct radiation, for climate statistics.
Supporting measurements
Temperature, wind and precipitation needed to interpret radiation data.
What your data can look like
Global radiation on a summer day, with the daily total calculated from the same series.
Example with made-up values.

Data collection
Data via telemetry to our data collection systems, with values checked before they are passed on.
Service
Cleaning, calibration as recommended by the manufacturer, and troubleshooting.
Equipment we use
We choose sensors for the accuracy the task requires.
Frequently asked questions
Which pyranometer do we need?
It depends on what the measurement is for. We help you choose a class under ISO 9060 to match your accuracy requirements and budget.
How often do the sensors need calibrating?
We follow the manufacturer’s recommendation and plan the calibration so that the data series isn’t broken.
Can you measure at an existing solar park?
Yes. We add sensors for radiation and temperature and route the data to your monitoring system.
