Description
Vorrichtungen zur Wandlung solarer Strahlungsenergie gibt es heute weltweit in vielen Ausführungen. Die bekanntesten sind die Photovoltaik (PV) und die Solarthermie.Devices for the conversion of solar radiation energy are available worldwide today in many versions. The best known are photovoltaic (PV) and solar thermal.
Die Photovoltaik zeichnet sich hierbei dadurch aus, dass bei der Wandlung der solaren Strahlungsenergie in einem sehr hohen Prozentsatz nur der elektrische Strom genutzt wird ohne die Nutzung der dabei immer auch auftretenden Wärme.Photovoltaics is characterized by the fact that in the conversion of solar radiation energy in a very high percentage only the electric power is used without the use of the always occurring heat.
Bei der Nutzung der Photovoltaik treten die folgenden bekannten Probleme auf:
- – bei der Einstrahlung erwärmen sich die Zellen, wodurch der Wirkungsgrad sinkt.
- – der Einstrahlungswinkel ist bei festmontierten Zellen nur für bestimmte Tages- und Jahreszeiten optimal,
- – aufgrund der Reflektion der solaren Strahlung müssen teure Gläser verwandt werden.
- – die solare Strahlung wird in sogenannten PV-Modulen in elektrischen Strom gewandelt, wobei diese Module in der Regel über Befestigungs- bzw. Aufstellvorrichtungen auf dem vorhandenen Untergrund, mehrheitlich auf Dächern, montiert werden.
- - When exposed to heat, the cells, whereby the efficiency decreases.
- - the angle of incidence is optimal for fixed cells only for certain times of the day and year,
- - Due to the reflection of solar radiation expensive glasses must be used.
- - The solar radiation is converted into so-called PV modules in electrical power, these modules are usually mounted on mounting or mounting devices on the existing surface, mostly on roofs.
Diese Probleme werden mit der erfindungsgemässen Neuerung gelöst.These problems are solved with the inventive innovation.
So sind die PV-Solarzellen in den Dachaufbau direkt intergriert, was zusätzliche Befestigungs- und Aufstellvorrichtungen entbehrlich macht.The PV solar cells are integrated directly into the roof structure, which eliminates the need for additional fastening and positioning devices.
Weiterhin kann der herkömmliche Modul-Aufbau mit einem Alurahmen entfallen, da die PV-Solarzellen direkt in die Dachfläche eingebracht werden können.Furthermore, the conventional module structure with an aluminum frame can be omitted since the PV solar cells can be introduced directly into the roof surface.
Die erfindungsgemäß neue Vorrichtung zur Wandlung der solaren Strahlungsenergie ist hierbei belüftet, wodurch der Luftstrom die Zellen kühlt und die Warmluft nutzbar wird wegen einer vorgegebenen Luftführung im Dachaufbau.The inventively new device for converting the solar radiation energy is ventilated here, whereby the air flow cools the cells and the hot air is available because of a given air flow in the roof structure.
Hierbei ist die erfindungsgemäß neue Vorrichtung darüberhinaus dadurch gekennzeichnet, dass den unterschiedlichen Einstrahlungswinkeln der solaren Strahlung besser Rechnung getragen wird, als bei den herkömmlichen, festmontierten Systemen.Here, the new device according to the invention is also characterized in that the different irradiation angles of the solar radiation is better taken into account, as in the conventional, fixed-mounted systems.
Der in der erfindungsgemäß neuen Vorrichtung zur Wandlung solarer Strahlung enthaltene Nachteil einer teilweisen, zeitlich begrenzten Verschattung der Fläche der PV-Solarzellen wird weitgehend dadurch wettgemacht, dass die an der Oberfläche reflektierte Strahlung in andere Solarzellen eingeleitet wird.The disadvantage of partial, temporally limited shading of the surface of the PV solar cells contained in the novel solar radiation conversion device according to the invention is largely offset by the fact that the radiation reflected at the surface is introduced into other solar cells.
Ein besonderer Vorteil der erfindungsgemässen Neuerung ist darin zu sehen, dass die Kosten für eine Sanierung der vielerorts noch vorhandenen Asbestzementdächer aus Wellplatten drastisch reduziert werden können, da die erfindungsgemäß neue Vorrichtung entweder direkt auf diese Dächer aufgesetzt wird, das vorhandene Dach als Bestandteil der Vorrichtung direkt genutzt wird oder aber zusätzlich lediglich die Demontagekosten der alten Asbestzementwellplatten anfallen sowie deren Entsorgung.A particular advantage of the inventive innovation is the fact that the cost of rehabilitation of corrugated asbestos cement roofs still available in many places can be drastically reduced because the new device according to the invention is either placed directly on these roofs, the existing roof as part of the device directly is used or additionally incurred only the disassembly costs of the old asbestos cement corrugated sheets and their disposal.
Ausserdem bewirkt die Schrägstellung der PV-Solarzellen in Verbindung mit der grösseren Wirkfläche der Zellen gegenüber rein flächigen Modulen bei Peak-Einstrahlung einen höheren Wirkungsgrad, da flächige Module hierbei sehr schnell an ihre Leistungsgrenzen stossen, was bei der Schrägstellung nicht der Fall ist.In addition, the inclination of the PV solar cells in conjunction with the larger effective area of the cells compared to purely flat modules at peak irradiance causes a higher efficiency, since area modules very quickly reach their performance limits, which is not the case in the oblique position.
Weiterhin können in die erfindungsgemässe Neuerung auch Absorberbleche anstelle der PV-Solarzellen bzw. zusammen mit den PV-Zellen eingebaut werden.Furthermore, absorber sheets can also be incorporated instead of the PV solar cells or together with the PV cells in the inventive innovation.
Ein Ausführungsbeispiel verdeutlich noch einmal die Vorteilhaftigkeit der Neuerung.An embodiment illustrates once again the advantage of the innovation.
