Development of a microprocessor-based sun-tracking system for solar collectors
Technical Report
·
OSTI ID:5320405
The development of a prototype sun-tracking system and the tests performed on it on an east-west trough solar collector array are described. The system includes a controller built around an RCA1802 microprocessor (..mu..P), a digital shaft encoder, and a heat flux sensor. The heat flux sensor consists of a fine resistance wire wrapped around the receiver tube. The wire is used to correct errors in calculated tracking angles arising from reflector imperfections and misalignments.
