Abstract

Different climatic factors can have an impact on the long-term performance of conventional solar panels, leading to problems like decreasing power output, interconnector failure, and cell fracture. Traditional modules, however, cannot be repaired in the event of any failure; instead, the entire unit must be replaced, even if the failure was largely caused by a single component. This thesis examines standard encapsulation methods, most common recycling procedures and presents a new approach design strategy for solar panels that makes it simple to access individual components, permitting upgrades, repairs, and modifications.
The proposed module configuration is composed of a double layer structure. The upper layer functions as a safeguarding glass cover, while the second layer is made up of solar cells that are adhered to a printed circuit board (PCB) that can endure high temperatures by using silver conductive epoxy. These two layers are separated by air gap layer and finally combined within an openable Aluminum frame with good sealing. To test the effectiveness of this new encapsulation technique, electrical and thermal analyses were conducted. An experimental study was conducted firstly. It is revealed through this experimental study that the dark and illuminated current-voltage characteristics are not affected when applying the new encapsulation technique. Furthermore, a theoretical thermal analysis is conducted to assess and compare the performance of the proposed module with that of the conventional module. Finally, some environmental tests have been performed to insure the reliability of the proposed module. According to the thermal analysis, the new approach encapsulation method is expected to result in slightly higher thermal stress on the solar cells compared to conventional encapsulation. Nevertheless, the novel encapsulation method presents benefits in relation to reliability and the ability to perform repairs. Thus, implementing the presented design can help conserve natural resources and reduce production costs.
