The solar array ,one of the main parts of the satellite's electrical power subsystem, is responsible for providing the required electrical power for the satellite during the mission. Micrometeorites and small space debris are considered serious risk for the satellite mission. Due to the number of satellites in orbit, space debris is increasing. The impact of micrometeorites or orbital debris on the solar panels of the satellite can damage the internal structure of the panel, which causes a drop in the electrical power of the satellite. In this article, along with the numerical and geometrical simulation of the solar panels of the MEO communication satellite, an algorithm based on the direct random impact of micrometeorites and orbital debris on the solar panels has been presented, and their damage rate has been calculated. The size of meteorites and space debris is determined based on the average size of the particles in the earth's orbit. After summarizing the collision results, the redundant solar panel has been simulated based on the minimum and maximum damage to compensate for the satellite power loss. The results show that the redundant solar panel can compensate the loss of satellite power after the collision and estimate the extent of damage as soon as possible
