Thermal Design and Analysis of Deployable Solar Panel Low Earth Orbit Equatorial Constellation Satellite

Solar panels on satellites are a particularly important requirement as the main power source for the needs of satellite operations in orbit. Solar panels on satellites facing the space environment will experience temperature degradation under different conditions in their orbital trajectories. These conditions usually occur in winter with a direction perpendicular to the solstice, deployable solar panels (DSP) will experience maximum worst-case conditions and cause maximum temperature changes. Therefore, we need a DSP that can survive in extreme space environmental conditions and maintain the temperature of the solar panel at its working temperature so that there is no decrease in efficiency which can result in a decrease in the power generated. DSP consists of solar panels and deployable plates. In this paper, finite element modeling, simulation, and analysis are used to validate the DSP thermal design using the FEM NX Space System Thermal software in transient conditions.
