Executive Summary : | solar PV systems face a significant issue where solar radiant flux does not result in 100% electrical power generation due to increased cell temperature. This results in a decrease in efficiency by about 0.5%. To address this, new materials and systems are needed to provide passive storage of thermal energy in PV panels. Phase change material (PCM) integrated PV panels can absorb and store heat dissipated from the PV surface, while PCM with nanoparticles can drop module temperatures by approximately 8°C and increase efficiency by around 5%. However, direct use of PCM or PCM with nanoparticles can cause premature leakage or instability. This research proposal focuses on developing highly thermal conductive ink/adhesive with EPCMs with reduced supercooling for PV panels. A smart condition monitoring system will be implemented for real-time monitoring, enhancing efficiency and output energy. The primary objective is to provide methods for encapsulating PCM with shell materials with enhanced thermal conductivity and mechanical strength. Multi-shell walls will be developed, and EPCMs will be embedded in a conductive ink-based adhesive. The study also aims to determine the time duration during which EPCM-embedded solar PV panels can maintain constant temperature under different weather conditions. The excess heat from PV panels will be utilized in passive heating devices. The real-time condition monitoring system will compare measuring parameters from PV panels with reference power, determining normal or affected output energy. The system will generate and transmit information through IoT devices for preventive maintenance. |
