BIBUS intelligent SunPOS sensor for photovoltic solar systems

BIBUS Hungary has developed an intelligent Sun position sensor for solar tracker systems. Thanks for the new technology innovations this newly developed Sun position sensor can increase the efficiency of the photovoltic solar tracker system, especially in case of the concentrating photovoltic (CPV)solar systems.

This system has the following advantages compared with the traditional Sun position sensors: 

• The system based on the GPS coordinates and time calculate the ecliptic coordinates and than the integrated high accuracy camera system can position the system exactly where the Sun is located (accuracy is +/- 0,1° of the sensor, the final system accuracy depend on the mechanical system), this guarantees the reachable highest efficiency for the solar system,

• The sensor continuously check the CPV modules voltage to reach the highest efficiency,
• The sensor can mount directly onto the solar tracker’s flag,
• Automatic SunPos sensor calibration assure the easy installation of the system,
• Maximum 256 pcs of SunPos sensor can connected serial through RS485 communication channel. 

Features: 

• Completly sealed sensor house (heatable),
• Aluminium house with stainless steel internal and external components,
• Special 32 bit microcontroller,
• On board GPS module,
• Weather station signal processing,
• Ethernet, RS485, USB and wireless communication,
• Image process system, built in ecliptic calculation for no Sun cases,
• Direct motor control (max. 1A AC/DC),
• Motor feedback and temperature sensing,
• Mechanical and software limit switch connection,
• Sensor internal temperature and moisture sensing,
• Special polar filter to protect the camera,
• Nanotechnology surface treatment can provide self cleaning lens,
• DriveGUI software on hungarian language,
• 100% hungarian development.
