Abstract
Die vorliegende Erfindung betrifft eine Vorrichtung zur Optimierung des Wirkungsgrades einer Photovoltaikanlage mit auf dem Dach (1) eines Gebäudes angeordneten Solarzellen (3) und mindestens einem das Dach (1) durchdringenden Schornstein (2), wobei der Schornstein (2) mindestens teilweise einfahrbar ausgebildet ist und der Einfahrvorgang in Abhängigkeit des Schattenwurfes (4) des Schornsteins (2) auf die Solarzellen (3) auslösbar ist.The present invention relates to a device for optimizing the efficiency of a photovoltaic system with on the roof (1) of a building arranged solar cells (3) and at least one roof (1) penetrating chimney (2), wherein the chimney (2) formed at least partially retractable is and the retraction operation in response to the shadow (4) of the chimney (2) on the solar cell (3) can be triggered.
Description
Die Erfindung betrifft eine Vorrichtung zur Optimierung des Wirkungsgrades einer Photovoltaikanlage nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for optimizing the efficiency of a photovoltaic system according to the preamble of
Photovoltaikanlagen haben in den vergangenen Jahren, nicht zuletzt aufgrund der steuerlichen Förderung, erhebliche Verbreitung gefunden und finden sich in vielen Gemeinden im Bundesgebiet, teilweise fast schon flächendeckend, auf den Dächern von Häusern, Hallen und anderen Gebäuden. Auf dem Dach angeordnet sind Solarkollektoren, welche in der Regel auf der Basis von Halbleitern arbeiten und aus dem auf sie treffenden Sonnenlicht Strom erzeugen. Dieser wird einer nachgeschalteten Steuereinheit zugeführt, welche den Strom nach Aufbereitung, insbesondere durch Wechselrichtung, entweder in das interne Stromnetz des Gebäudes oder in das öffentliche Netz einspeist.Photovoltaic systems have found in recent years, not least due to the tax incentives, widespread and found in many communities in the Federal territory, sometimes almost nationwide, on the roofs of houses, halls and other buildings. Arranged on the roof are solar collectors, which usually work on the basis of semiconductors and generate electricity from the sunlight that hits them. This is fed to a downstream control unit, which feeds the power after treatment, in particular by changing direction, either in the internal power system of the building or in the public network.
Bekanntermaßen funktionieren Photovoltaikanlagen nur dann mit hohem Wirkungsgrad, wenn die Sonne scheint, insbesondere bei wolkenlosem Himmel. Ferner ist bekannt, dass Photovoltaikanlagen relativ empfindlich gegen Beschmutzung sind. Eine nur leichte, kaum sichtbare Verschmutzung der Oberfläche der Solarzellen kann zu einer Senkung des Wirkungsgrads um 10 bis 15% führen.As is known, photovoltaic systems only work with high efficiency when the sun is shining, especially in clear skies. It is also known that photovoltaic systems are relatively sensitive to contamination. An only slight, barely visible contamination of the surface of the solar cells can lead to a reduction of the efficiency by 10 to 15%.
Darüber hinaus hat es sich herausgestellt, dass in manchen Fällen trotz gereinigter Solarzellen und bei wolkenlosem Himmel der Wirkungsgrad der Photovoltaikanlage zu bestimmten Tageszeiten deutlich geringer ist und teilweise sogar Werte erreicht, die so gering sind, dass sie dem Wirkungsgrad bei verdecktem Himmel entsprechen.In addition, it has been found that in some cases, despite clean solar cells and cloudless sky, the efficiency of the photovoltaic system at certain times of day is significantly lower and sometimes even reaches values that are so low that they correspond to the efficiency in a covert sky.
Es besteht daher die Aufgabe, eine Vorrichtung zur Optimierung des Wirkungsgrades einer Photovoltaikanlage mit auf dem Dach eines Gebäudes angeordneten Solarzellen so zu optimieren, dass ein von der Tageszeit weitgehend unabhängiger, hoher Wirkungsgrad erzielt wird.It is therefore the object to optimize a device for optimizing the efficiency of a photovoltaic system with arranged on the roof of a building solar cells so that a largely independent of the time of day, high efficiency is achieved.
Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüche entnehmbar.This object is achieved with the characterizing features of
Ein Ausführungsbeispiel der Erfindung wird im Folgenden unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert. Diese zeigen:An embodiment of the invention will be explained in more detail below with reference to the accompanying drawings. These show:
Erfindungsgemäß wurde erkannt, dass der Schattenwurf von das Dach
Dieser negative Effekt kann erfindungsgemäß dadurch reduziert bzw. ganz beseitigt werden, dass der das Dach
Durch das Einfahren des Schornsteins
Das Einfahren des Schornsteins
Selbstverständlich kann die hierfür erforderliche Steuerung eine Sperrvorrichtung haben, die, z. B. bei benötigter Wirkung des Schornsteins, das Einfahren für diesen Fall verhindert.Of course, the control required for this purpose may have a locking device which, for. B. at the required effect of the chimney, the retraction for this case prevented.
