Title:
SUN AZIMUTH SENSOR
Document Type and Number:
WIPO Patent Application WO/2008/037158
Kind Code:
A1
Abstract:
A sun azimuth sensor comprises a housing and a photo detector (200a). A slit allowing sunlight
to pass through is provided on the top of the housing. The photo detector includes
a first and a second photoelectric detective elements (201,202) in the same shape.
The two photoelectric detective elements are made of the same photosensitive
base, and are able to respond to the sunlight from the slit respectively and produce
an electric signal. There is a given relationship between the output electric
signal and the azimuth angle of the solar panel, so that the adjustment precision
of the solar panel is improved.
