The SR15-D2A2 Pyranometer is an advanced instrument used to measure solar radiation, specifically the global solar radiation received by a horizontal surface. It is part of the pyranometer family, which are devices that measure the intensity of sunlight or solar radiation reaching the Earth's surface.

1. Solar Power Efficiency: To ensure solar panels and systems are performing optimally, it’s crucial to measure how much solar radiation is available. The SR15-D2A2 provides real-time data for this.

2. Climate & Environmental Studies: The device offers scientists critical data needed to study the effects of solar radiation on the climate and ecosystems.

3. Accurate Data: With a wide measurement range and precision, it’s suitable for a wide array of professional applications, ensuring that users can make data-driven decisions.

Calibration of SR15 pyranometer has been improved; our latest calibration method results in an uncertainty of the sensitivity of 1.8 %, compared to typical uncertainties of higher than 2.8 % for this pyranometer class. SR15’s response time is < 10 s, a significant improvement relative to earlier sensors and competitors.

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 SR15 may be used, in combination with appropriate software,
to estimate sunshine duration. This is much more cost-effective than using a dedicated sunshine.
