Abstract

The automatic sun tracking appts. has solar modules or photodiodes (1,2) mounted on a block and are set at angles to each other. Mounted above the surface are a pair of mirrors (4,5) which - depending upon the direction of the sun's rays - either act as shields or reflectors. When the sun's rays are aligned equally with both mirrors the same electrical outputs are obtained. The solar modules or photodiodes are connected in antiparallel form to a motor that operates to seek alignment with the sun. ADVANTAGE - Reduces effect of variations in electrical characteristics of solar module or photodiode.

Description

(Zusatz zu Patentanmeldung P 43 06 656.9 )(Addition to patent application P 43 06 656.9)

In der Hauptanmeldung P 43 06 656.9 ist in Fig. 5 eine aus zwei Solarmodulen (1) und (2) bestehender Detektor ge­ zeigt, bei dem die Versteilerung der Spannungskennlinie durch einen Schattenwerfer bewirkt wird, während in Fig. 6 der Haupt­ anmeldung die Kennlinienversteilerung durch eine Spiegel­ anordnung erzeugt wird. Nach Fig. 1 dieser Zusatzanmeldung lassen sich Schattenwerfer und Spiegelanordnung auf besonders einfache Weise vereinigen. Dazu sind vor beiden Solarmodulen (1) und (2) in Richtung auf die Sonne zu zwei Spiegelflächen (4) und (5) angebracht, die auch als Schattenwerfer arbeiten können. Diese Art des optischen Verfahrens hat nicht nur wie schon bei denen in der Hauptanmeldung beschriebenen die Ver­ größerung der Kennliniensteilheit in der Nähe von γ=0 zur Folge, sondern gleicht auch die unvermeidlichen Streuungen der elektrischen Eigenschaften der Solarmodule oder Photo­ dioden in entsprechender Weise aus.In the main application P 43 06 656.9 in Fig. 5 is a ge of two solar modules ( 1 ) and ( 2 ) existing detector shows, in which the steepening of the voltage characteristic is caused by a shadow projector, while in Fig. 6 the main application, the characteristic distribution is generated by a mirror arrangement. According to FIG. 1 of this additional application, the shadow projector and mirror arrangement can be combined in a particularly simple manner. For this purpose, two mirror surfaces ( 4 ) and ( 5 ) are attached in front of both solar modules ( 1 ) and ( 2 ) in the direction of the sun, which can also work as shadow projectors. This type of optical method not only results in the increase in the slope of the characteristic near γ = 0, as already described in the main application, but also compensates for the inevitable scatter in the electrical properties of the solar modules or photo diodes in a corresponding manner.
