Solar power generation is increasing dramatically because of environmental friendly and available energy source compared to other renewable energy sources. One of the major threats of expansion of solar power system is lightning damage. So, the induced voltage on power condition system (PCS) of solar power system due to different places of nearby lightning strike is analyzed using electromagnetic field analysis approach, and the cause of damage of system is investigated. It is found that the maximum induced voltage change per unit distance is observed 5kV changing strike point vertically from the prescribed point, and minimum voltage is observed for horizontal changes. In addition, the induced voltage is found excessive at high rate of rise time of lightning strike currents. The induced voltage is studied with the help of FDTD method. Virtual Surge Test Lab (VSTL) is used for FDTD calculations, which solve Maxwell's electromagnetic equations with minimum approximations. The model of solar power system was represented with thin wire, which is a good approximation of power line and steel frame.
