Hintergrund der ErfindungBackground of the invention

Eine eine Nachführeinrichtung aufweisende Photovoltaikanlage ist beispielsweise aus der DE 10 2005 01 4 320 A1 bekannt. Die Nachführeinrichtung weist hierbei eine mechanische Kopplung zwischen der vertikalen und der horizontalen Nachführung eines Photovoltaikmoduls auf. Prinzipiell ist aus der DE 10 2005 014 320 A1 auch die Möglichkeit bekannt, für die Nachführung eines Photovoltaikmoduls Rückkopplungsmechanismen zu verwenden, wobei in diesem Fall an den Nachführeinrichtungen oder an den Photovoltaikmodulen Messsensoren vorhanden sind. Details zur Mess- oder Regeltechnik sind in der DE 10 2005 014 320 A1 nicht offenbart.A tracking device having photovoltaic system is for example from the DE 10 2005 01 4 320 A1 known. In this case, the tracking device has a mechanical coupling between the vertical and the horizontal tracking of a photovoltaic module. In principle, from the DE 10 2005 014 320 A1 Also known is the possibility to use for the tracking of a photovoltaic module feedback mechanisms, in which case measuring sensors are present on the tracking devices or on the photovoltaic modules. Details of the measuring or control technology are in the DE 10 2005 014 320 A1 not revealed.

Aus der DE 201 10 240 U1 ist ein Sonnenlicht-Sensor für Nachführungssysteme bekannt. Dieser Sensor umfasst eine Anordnung von drei gemeinsam in der Draufsicht die Form eines Y bildenden Platten, von denen zwei im Wesentlichen rechtwinklig zueinander angeordnet sind. Auf denjenigen Seiten dieser Platten, die der dritten Platten zugewandt sind, ist jeweils ein photovoltaisches Element angeordnet. Zusätzlich trägt eine der beiden zueinander rechtwinkligen Platten auch auf der der dritten Platte abgewandten Seite ein photovoltaisches Element. Zum Betrieb eines Solarkollektors oder Moduls werden zwei rechtwinklig zueinander montierte Sonnenlicht-Sensoren benötigt, wobei der eine Sensor zur Ausrichtung Azimut und der andere Sensor zur Ausrichtung Elevation dient.From the DE 201 10 240 U1 is a sunlight sensor for tracking systems known. This sensor comprises an arrangement of three plates, which together in plan view form the shape of a Y-forming plate, two of which are arranged substantially at right angles to one another. On those sides of these plates, which face the third plates, a photovoltaic element is arranged in each case. In addition, one of the two mutually perpendicular plates also carries a photovoltaic element on the side facing away from the third plate. To operate a solar collector or module, two sunlight sensors mounted at right angles to each other are required, one serving to align azimuth and the other to orient elevation.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine Photovoltaikanlage mit einer gegenüber dem Stand der Technik verbesserten, insbesondere rationell herstellbaren sowie im langjährigen Einsatz robusten Nachführeinrichtung anzugeben.Of the Invention is the object of a photovoltaic system with an improved over the prior art, in particular rationally producible as well as robust for many years Specify tracking device.

Zusammenfassung der ErfindungSummary of the invention

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Photovoltaikanlage mit den Merkmalen des Anspruchs 1. Diese Photovoltaikanlage umfasst ein Solarpanel mit mehreren starr miteinander verbundenen, nicht in einer einzigen Ebene angeordneten Segmenten, wobei jedes Segment zur photovoltaischen Erzeugung elektrischer Energie geeignet ist. Weiter umfasst die Photovoltaikanlage eine vorzugsweise mehrachsige Nachführeinrichtung, welche zur Ausrichtung des Solarpanels nach dem Sonnenstand vorgesehen ist. Zumindest ein Teil der Segmente des Solarpanels wird sowohl zur Energieerzeugung als auch zur Detektion der Intensität der einstrahlenden Sonnenstrahlung zum Zweck der sonnenstandsabhängigen Nachführung des Solarpanels verwendet. Hierbei bildet die Relation zwischen den mittels verschiedener Segmente detektierten Bestrahlungsintensitäten eine Regelgröße der Nachführung.These The object is achieved by a photovoltaic system with the features of claim 1. This Photovoltaic system includes a solar panel with several rigidly interconnected connected, not in a single plane arranged segments, wherein each segment for photovoltaic generation of electrical Energy is suitable. Furthermore, the photovoltaic system includes a preferably multiaxial tracking device, which for Orientation of the solar panel is provided according to the position of the sun. At least part of the segments of the solar panel will be both to Energy generation as well as for the detection of the intensity the einstrahlenden solar radiation for the purpose of the sunlight dependent Tracking the solar panel used. Here forms the Relation between the detected by means of different segments Irradiation intensities a controlled variable the tracking.

In bevorzugter Ausgestaltung weist das Solarpanel eine rechteckige Grundform mit einem zentralen Hauptsegment und vier an dessen Seiten angeordneten Nebensegmenten auf. Sowohl die Abmessungen zweier einander gegenüberliegender, im Wesentlichen streifenförmiger, auch als Sensorsegmente bezeichneter Nebensegmente als auch deren Schrägstellungswinkel gegenüber dem zentralen Hauptsegment stimmen hierbei vorzugsweise überein. Eine vollständige Umrahmung des Hauptsegments mit gegenüber diesem schräg gestellten Nebensegmenten gibt der Gesamtanordnung der Segmente eine dreidimensionale Struktur, welche dem Solarpanel eine im Vergleich zu durchgängig flächigen Panels erhöhte mechanische Stabilität verleiht.In preferred embodiment, the solar panel has a rectangular Basic form with a central main segment and four at its sides arranged sub-segments on. Both the dimensions of two each other opposite, substantially strip-shaped, Also referred to as sensor segments sub-segments as well as their skew angle in this case preferably coincide with the central main segment. A complete framing of the main segment with opposite this biased sub-segments gives the overall arrangement the segments have a three-dimensional structure, which is the solar panel one compared to consistently flat panels gives increased mechanical stability.

Der Vorteil der Erfindung liegt insbesondere darin, dass zur geregelten Ausrichtung eines Solarpanels nach dem Sonnenstand keine gesonderten Sensoreinrichtungen sondern eine Mehrzahl einen definierten Winkel zueinander einschließende, der photovoltaischen Energieerzeugung dienende Panel-Segmente verwendet werden. Um eventuelle Serienstreuungen einzelner Panel-Segmente, insbesondere Sensorsegmente, zu kompensieren, kann eine Kalibrierung der Photovoltaikanlage unter Laborbedingungen, das heißt mit Bestrahlung des Solarpanels mittels einer künstlichen Lichtquelle, erfolgen.Of the Advantage of the invention is in particular that the regulated Orientation of a solar panel according to the position of the sun no separate sensor devices but a plurality of a defined angle enclosing each other, photovoltaic power generation panel segments used become. For possible series deliveries of individual panel segments, In particular, sensor segments to compensate, can be a calibration the photovoltaic system under laboratory conditions, that is with irradiation of the solar panel by means of an artificial Light source, done.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Hierin zeigen:following an embodiment of the invention with reference to a Drawing explained in more detail. Herein show:

2 in symbolisierter Draufsicht sowie verschiedenen Schnitten ein Solarpanel der Photovoltaikanlage nach 1. 2 in a symbolized plan view and various sections a solar panel of the photovoltaic system 1 ,

Ausführliche Beschreibung der ZeichnungDetailed description the drawing

Eine in 1 grob vereinfacht dargestellte Photovoltaikanlage 1 umfasst eine Stützkonstruktion 2 mit einer Nachführeinrichtung 3 sowie ein an der Stützkonstruktion 2 mehrachsig verstellbar angelenktes Solarpanel 4. Die gesamte Photovoltaikanlage 1 ist beispielsweise auf dem Erdboden oder auf dem Dach eines Gebäudes installierbar.An in 1 roughly illustrated photovoltaic system 1 includes a support structure 2 with a tracking device 3 as well as at the support structure 2 multiaxially adjustable articulated solar panel 4 , The entire photovoltaic system 1 For example, it can be installed on the ground or on the roof of a building.

Das Solarpanel 4 umfasst, wie aus 2 hervorgeht, ein zentrales, rechteckiges Hauptsegment 5 sowie vier dieses rahmenförmig umschließende Nebensegmente 6, 7, 8, 9. Jedes der Panel-Segmente 5, 6, 7, 8, 9 umfasst eine Mehrzahl an Photovoltaikzellen 10, die ausnahmslos zur Erzeugung elektrischer Energie vorgesehen sind. Wie aus 1 sowie den Schnitten in 2 ersichtlich ist, sind die einzelnen Nebensegmente 6, 7, 8, 9, welche auch als Sensorsegmente bezeichnet werden, jeweils gegenüber dem Hauptsegment 5 verkippt angeordnet. Dies hat zur Folge, dass die Sonnenstrahlung nie alle Segmente 5, 6, 7, 8, 9 im gleichen Winkel treffen kann. In der Anordnung nach 1 trifft die Sonnenstrahlung beispielsweise senkrecht auf das Nebensegment 6, während alle anderen Segmente 5, 7, 8, 9 unter einem mehr oder weniger spitzen Winkel der Sonnenstrahlung ausgesetzt sind. Die im Nebensegment 6 photovoltaisch generierte Spannung ist somit größer als die im gegenüberliegenden Nebensegment 8 generierte elektrische Spannung. Die beiden genannten Spannungen werden einem Vergleicher in der Nachführeinrichtung 3 zugeführt, der somit eine Spannungsdifferenz bereitstellt, welche als Regelgröße verwendet wird. Die optimale Ausrichtung des Solarpanels 4 ist dann gegenben, wenn die mittels des Nebensegments 6 generierte elektrische Spannung der mittels des Nebensegments 8 generierten Spannung entspricht. Analoges gilt für die einander gegenüberliegenden Nebensegmente 7, 9. Da jedes der Nebensegmente 6, 7, 8, 9 eine Vielzahl an Photovoltaikzellen 10 enthält, ist die Nachführeinrichtung 3 weitgehend unempfindlich gegenüber äußeren Einwirkungen auf das Solarpanel 4, beispielsweise Verschmutzungen oder unbeabsichtigten Abschattungen einzelner Photovoltaikzellen 10.The solar panel 4 includes, how out 2 shows, a central, rectangular main segment 5 and four of these frame-shaped enclosing sub-segments 6 . 7 . 8th . 9 , Each of the panel segments 5 . 6 . 7 . 8th . 9 includes a plurality of photovoltaic cells 10 , which are provided without exception for the production of electrical energy. How out 1 as well as the cuts in 2 it can be seen that the individual subsegments are 6 . 7 . 8th . 9 , which are also referred to as sensor segments, respectively with respect to the main segment 5 arranged tilted. As a result, solar radiation never reaches all segments 5 . 6 . 7 . 8th . 9 can hit at the same angle. In the arrangement according to 1 For example, the solar radiation hits the secondary segment vertically 6 while all other segments 5 . 7 . 8th . 9 are exposed to solar radiation at a more or less acute angle. The in the secondary segment 6 photovoltaic generated voltage is thus greater than that in the opposite sub-segment 8th generated electrical voltage. The two voltages mentioned become a comparator in the tracking device 3 supplied, thus providing a voltage difference, which is used as a controlled variable. The optimal orientation of the solar panel 4 is then opposite, if by means of the secondary segment 6 generated electrical voltage by means of the secondary segment 8th generated voltage corresponds. The same applies to the opposite side segments 7 . 9 , Because each of the subsegments 6 . 7 . 8th . 9 a variety of photovoltaic cells 10 contains, is the tracking device 3 largely insensitive to external influences on the solar panel 4 For example, soiling or unintentional shadowing of individual photovoltaic cells 10 ,
