UV Spectroradiomter on Sun tracker for direct solar irradiance measurement and TOC determination
- Precise Sun Tracker with 4 Quadrant Diode for fine alignment
- Highest stray light reduction for precise TOC determination, evaluated in scientific intercomparisons to Brewer and Dobson
- Compact size
- Weather proof
- Included software
Accuracy shown in intercomparison measurement campaigns
The BTS-Solar has been compared to Brewer and Dobson in several scientific publications to verify and show the measurement capabilities. These showed an excellent agreement, see, long term intercomparion at DWD (Deutscher Wetterdienst) and International Intercomparion at Izaña Atmospheric Observatory/Teneriffa .
Measurement system for direct spectral irradiance measurements of solar radiation. The system consistent of a BTS2048-UV-S-WP (Spectroradiometer with tube), SUT-1711 (Suntracker), SUT-Z01 (Sunfinder), SolarRunner (Software) and connection cables. Evaluations like TOC (Total Ozone Column) are supported by the measurement system.
Compact sun tracker design
The SUT-1711 is a compact sun tracker for worldwide use under all weather conditions. It is equipped with a tripod stand and a spirit level for adjustment.
Payload designed for single devices
The accurate motion system does not require maintenance. The maximum payload depends on the resulting leverage and is typically limited to 5.5 kg. The unit is perfectly suited for the BTS2048-xx-WP series.
Fine sun tracking accessory
For extended accuracy sun tracking a direct sun sensor with integrated GPS receiver and four quadrant diode can be used as an accessory (SUT-Z01). This system automatically configures location and provides precise time information. This sensor is usually connected with the measurement device and communicates via the application software with the sun tracker.
The SolarRunner software is the application software for the full measurement system.
In addition the SUT-1711 can be controlled by a software development kit (SDK) or by the application software of the used Gigahertz-Optik GmbH measurement device (e.g. BTS2048-xx-WP series). The software automatically controls the SUT-1711 in order to track the sun position depending on the GPS position and time. For even more precise control and automatic setup the fine sun tracking accessory SUT-Z01 is recommended.
