Description

Kurzfassung:Short version:

Kühlvorrichtungen für PV-Solarmodule erhöhen den Ertrag der Solaranlage. Die gekühlten PV-Solarmodule erzeugen einen höheren Energieertrag, weil die thermischen Verluste durch die Kühlung geringer werden. Die hier beschriebenen Kühlvorrichtungen können die Vorderseite und/oder die Rückseite des PV-Solarmoduls kühlen. Bei der Vorderseitenkühlung wird gleichzeitig mit der Kühlung noch eine Reinigung der PV-Solarmodule erreicht.Cooling devices for PV solar modules increase the yield of the solar system. The cooled PV solar modules generate a higher energy yield because the thermal losses due to cooling are lower. The cooling devices described herein may cool the front and / or rear of the PV solar module. In the front cooling, cleaning of the PV solar modules is achieved simultaneously with the cooling.

Die vorderseitigen Kühlvorrichtungen können erst installiert werden, wenn die PV-Solaranlage bereits aufgebaut ist, können also nur nachträglich installiert werden.The front-side cooling devices can only be installed when the PV solar system is already set up, so they can only be retrofitted.

Die rückseitigen Kühlvorrichtungen können bereits während der Produktion der PV-Solarmodule auf die Rückseite der Module montiert werden aber auch nachträglich, wenn die PV-Solaranlage schon besteht.The rear cooling devices can already be mounted on the back of the modules during the production of the PV solar modules, but also retroactively if the PV solar system already exists.

Anwendungsgebiet:Field of use:

Kühlung und Reinigung von bereits montierten PV-Solarmodulen.Cooling and cleaning of already installed PV solar modules.

Wasserschwall-Kühl- und Reinigungsvorrichtung für PV-SolarmoduleWaterfall cooling and cleaning device for PV solar modules

Leider erzeugt die Sonneneinstrahlung in den Photovoltaik Solarmodulen nicht nur Strom, sondern auch Wärme. Diese Wärme wirkt sich schädlich auf den Ertrag der PV-Module aus. An warmen Sommertagen kann die Scheiben- und somit auch die Zellen-Temperatur in einem Solarmodul leicht 80–90°C und mehr erreichen, besonders in südeuropäischen Gegenden (Mittelmeerraum).Unfortunately, the solar radiation in the photovoltaic solar modules generates not only electricity, but also heat. This heat has a detrimental effect on the yield of the PV modules. On warm summer days, the disc and thus the cell temperature in a solar module can easily reach 80-90 ° C and more, especially in southern European areas (Mediterranean).

Es ist bekannt, dass z. B. kristalline Solarmodule einen Minderertrag von ca. 0,5%/°C liefern. Ein Modul, das z. B. auf der Scheibe an warmen Tagen eine Temperatur von 65°C erreicht, was sogar in Deutschland oft vorkommt, verliert dadurch ca. 20% an Leistung. Gemessen wird die Leistung eines Moduls bei der Herstellung bei 25°C unter sogenannten STC (Standard-Test-Conditions). Eine Temperatur von 65°C stellt somit eine Erhöhung gegenüber der STC-Temperatur um 40°C dar. Multipliziert mit dem Verlustfaktor von 0,5%/°C erhält man dann den für 65°C üblichen Verlust von 20%.It is known that z. B. crystalline solar modules provide a reduced yield of about 0.5% / ° C. A module that z. B. on the disk on warm days reaches a temperature of 65 ° C, which often occurs even in Germany, thereby loses about 20% of power. The performance of a module in the production at 25 ° C under so-called STC (Standard Test Conditions) is measured. A temperature of 65 ° C thus represents an increase of 40 ° C compared to the STC temperature. Multiplied by the loss factor of 0.5% / ° C, the usual 65 ° C loss of 20% is obtained.

Ein 200 Wp Modul hat dann nur noch eine Leistung von 160 Wp, denn 20% von 200 Wp ist ein Verlust von 40 Wp. Noch schlimmer werden die Verluste durch die hohen Temperaturen in Südeuropa.A 200 Wp module then only has a power of 160 Wp, because 20% of 200 Wp is a loss of 40 Wp. The losses are even worse by the high temperatures in southern Europe.

Bei Scheibentemperaturen von z. B. 85°C steigen die Verluste dann sogar auf 30% und das 200 Wp Modul liefert nur noch 140 Wp.At disk temperatures of z. B. 85 ° C, the losses even rise to 30% and the 200 Wp module delivers only 140 Wp.

Wp bedeutet, das die angegebene Leistung des Moduls nur unter STC Bedingungen gilt:
(Sonneneinstrahlung: 1000 W/m2, Messtemperatur: 25°C, Sonnenspektrum: AM 1.5).Wp means that the specified power of the module is only valid under STC conditions:
(Solar radiation: 1000 W / m 2 , measuring temperature: 25 ° C, solar spectrum: AM 1.5).

Eine optimale Kühlung der Module würde also den Ertrag signifikant steigern.Optimum cooling of the modules would thus significantly increase the yield.

Stand der Technik:State of the art:

Es gibt bereits Hybridmodule, bei denen ein in die Rückwand integriertes Kühlsystem durch die Kühlung mittels eines Kühlmediums (meist Wasser oder Wasser mit Glykol) den Stromertrag verbessert. Diese Vorrichtungen sind recht kompliziert in der Montage und auch die Auswechselung eines Moduls im Störungsfall ist so kompliziert, dass bei manchen Vorrichtungen erst andere Module abgebaut werden müssen, bevor das defekte Modul zwecks Auswechselung demontiert werden kann.There are already hybrid modules in which a cooling system integrated into the rear wall by cooling by means of a cooling medium (usually water or water with glycol) improves the power yield. These devices are quite complicated to install and also the replacement of a module in case of failure is so complicated that in some devices only other modules must be dismantled before the defective module can be dismantled for the purpose of replacement.

Nachteile anderer Vorrichtungen:Disadvantages of other devices:

Es gibt bereits Solarmodul-Vorderseiten-Kühlsysteme ( DE 10 2007 059 202 A1 ), die zur Kühlung der Module eine Sprinkleranlage benutzen. Sprinklersysteme haben aber den großen Nachteil, dass die Sprinklerdüsen schnell verstopfen (Schmutz, Kalk, etc.) und die Module dann nicht mehr optimal gekühlt und gereinigt werden und dass eine Menge Wasser beim Kühlen über den Rand der Module spritzt und somit dem Kühlkreislauf verloren geht. Zusätzlich steht das Sprühsystem unter einem hohen Druck, damit auch alle Module beim Sprühen vom Wasser erreicht werden. Hoher Druck bedeutet aber eine hohe Pumpleistung und das wiederum bedeutet hohe zusätzliche Pumpen-Energie, also Strom, der für dieses System aufgebracht werden muss und der die zusätzliche Ertragsgewinnung schmälert.There are already solar panel front cooling systems ( DE 10 2007 059 202 A1 ), which use a sprinkler system to cool the modules. But sprinkler systems have the big disadvantage that the sprinkler nozzles clog quickly (dirt, lime, etc.) and the modules are then no longer optimally cooled and cleaned and that a lot of water splashes on cooling over the edge of the modules and thus lost the cooling circuit , In addition, the spraying system is under a high pressure, so that all modules are reached when spraying from the water. However, high pressure means a high pumping capacity and this in turn means high additional pump energy, ie electricity that must be applied to this system and which reduces the additional yield.

Neu an der Erfindung:New to the invention:

Neu an der Erfindung gegenüber anderen bereits bekannten, wasserverbreitenden Vorrichtungen ist der ständige Wasserschwall, der nicht nur kühlt, sondern auch stärkere Verschmutzungen wie z. B. Vogelkot wirkungsvoll beseitigt und der gegenüber einer Sprinkleranlage weitere Verbesserungen bietet.New to the invention over other already known, water-spreading devices is the constant stream of water, which not only cools, but also stronger pollution such. B. bird droppings effectively eliminated and offers over a sprinkler system further improvements.

Eine Wasserschwall-Vorrichtung, welche das Modul von außen kühlt und dabei noch eine reinigende Wirkung hat, hat da Vorteile, da eine solche Vorrichtung auch noch nachträglich an einer bereits bestehenden PV-Solaranlage montiert werden kann. A waterfall device, which cools the module from the outside while still having a cleaning effect, has since advantages, since such a device can also be retrofitted to an existing PV solar system.

Steuerelektronik:Control electronics:

Die Wasserschwall-Kühlvorrichtung verfügt über eine Steuerelektronik, die in Abhängigkeit von der Scheibentemperatur des Solarmoduls den Kühlprozess steuert. So setzt bei hoher Scheibentemperatur öfter eine Schwallkühlung ein als bei niedriger Scheibentemperatur. Dadurch wird der zusätzliche Mehrertrag optimiert.The waterfall cooling device has control electronics that control the cooling process as a function of the temperature of the pane of the solar module. For example, at high wheel temperatures, chilling is more frequent than at low pulley temperatures. This optimizes the additional yield.

übrige Komponentenremaining components

Das Wasser wird entsprechend dem Stand der heutigen bekannten Technik über eine Auffangrinne wieder in den Vorratsbehälter zurückgeführt, von dem es wieder zur Wasserschwall-Kühlvorrichtung hochgepumpt wird.The water is returned to the state of today's known technology via a gutter back into the reservoir from which it is pumped up again to the waterfall cooling device.

Bei Bedarf kann auch ein zusätzlicher Wärmetauscher oder ein Wasserkühler eingesetzt werden, damit die Wassertemperatur ihre Kühlfunktion nicht verliert.If required, an additional heat exchanger or a water cooler can be used so that the water temperature does not lose its cooling function.

Die Wasserschwall-Kühlvorrichtung ist so konstruiert, das es sich um eine für diese Branche neuartige Kühlvorrichtung handelt, die mit ihrer Schwallkühlung gegenüber den bereits bekannten Kühlsystemen deutliche Vorteile aufweist.The waterfall cooling device is designed to be a novel cooling device for this industry, with its surge cooling over the already known cooling systems has significant advantages.
