Optoelectronic Sensor for Solar Installations
Maximum precise tracking of the sun‘s diurnal position by solar collectors ensures a high harvest ratio and thus good solar collector etficiency. Two-axis tracking is effected by adjustable d. c. motors which are controlled by signals emitted from the sensor.
Application and Characteristics
measurement of the optical deviation and readjustment within < 0.02° (0.3 mrad)
- sensitivity (adjustable) >100 W/m² insolation
- response time > 0.1 sec
- acceptance angle + 0.75%
The sensor for tracking as described above can be used tor:
- parabolic or spherical concentrators (parabolic disk) according to th. solar farm principle
- heliostats or heliostat fields for solar tower installations (required accuracy 0.02°-0,1°)
- test facilities for solar high-temperature generation with concentration ratlos above 1000
- comparison of the target / actual position in computer-cqntrolld solar installations
- and generally for measuring the angular deviation from a remote Iight source and tor tracking mobile light sources (e. g. navigation).
