Solar Panel Temperature Reduction Study of FORMOSAT-5 Satellite
並列摘要
A small satellite equipped with a self-developed bus with the high-resolution optical remote sensing instrument (RSI) by integrating NSPO with the ITRC (Instrument Technology Research Center) of NARL was developed under the FORMOSAT-5 satellite program. Solar cell efficiency is temperature related. When the solar panel temperature is over 75℃, the efficiency degrades apparently. FORMOSAT-5 satellite solar power system is compacted due to the limited solar panel sizes at the current configuration. Reducing solar panel temperatures could help increase the availability of generated solar power. The objective of this thermal analysis is to reduce the solar array temperature by thermal control design. The solar panel temperatures with and without radiator under various thermal conditions including different beta angles, summer and winter seasons, solar panel configuration, and operating modes as supplied by electric power subsystem (EPS) designers are calculated. From different case studies and with radiators applied to the solar panels backside, the thermal control subsystem (TCS) predict solar panel flight temperature and support data to EPS subsystem predict the power margin. The power margin percentage will increase best to about 8.20% from EPS subsystem predictions and at this condition the maximum temperature can be reduced from 103℃ to 95.7℃ or about 7.3℃ for hot condition. This improves the solar panel efficiency for hot condition.
