Improving the Performance of PV Solar Panels
ISBN: 9786205519424 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Among the factors affecting the efficiency of PV panels is the overheating. For every 1oC rise in temperature, the efficiency of the PV panel drops by 1%. The objective of this research is to develop new technique for improving the performance of Photovoltaic (PV) panels. Two technologies were proposed to improve the performance of the PV panels. The first technique is coating the panel by oil in order to improve the absorptivity of the panel surface. It was found that coating the PV panel with a layer of Labovac oil of a thickness of 10 mm, improves the efficiency of the PV panel by more...

Améliorer les performances des panneaux solaires photovoltaïques
ISBN: 9786205564073 / Francuski / Miękka / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. La surchauffe est l'un des facteurs qui affectent l'efficacité des panneaux photovoltaïques. Pour chaque augmentation de 1°C de la température, l'efficacité du panneau PV diminue de 1%. L'objectif de cette recherche est de développer une nouvelle technique pour améliorer la performance des panneaux photovoltaïques (PV). Deux technologies ont été proposées pour améliorer la performance des panneaux PV. La première technique consiste à enduire le panneau d'huile afin d'améliorer l'absorptivité de la surface du panneau. Il a été constaté que le revêtement du panneau PV avec...

Verbesserung der Leistung von PV-Solarmodulen
ISBN: 9786205564059 / Miękka / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Zu den Faktoren, die den Wirkungsgrad von PV-Paneelen beeinflussen, gehört die Überhitzung. Für jeden Temperaturanstieg von 1°C sinkt der Wirkungsgrad des PV-Panels um 1 %. Ziel dieser Forschungsarbeit ist die Entwicklung neuer Techniken zur Verbesserung der Leistung von Photovoltaik (PV)-Paneelen. Es wurden zwei Technologien vorgeschlagen, um die Leistung der PV-Paneele zu verbessern. Die erste Technik ist die Beschichtung des Panels mit Öl, um die Absorptionsfähigkeit der Paneloberfläche zu verbessern. Es wurde festgestellt, dass die Beschichtung der PV-Paneele mit einer 10 mm dicken...
