Abstract

This paper presents the study of lightning protection factors for photovoltaic power generation systems. The induced voltages were investigated obtained from the lightning effects and inductance due to the lightning effects on structures and conductors in this system. After that, a model of the lightning effects on the structure was simulated using a MATLAB program. The model was developed as a simple photovoltaic system consisting of a typical arrangement of solar panels, the height between the panel and the aluminum profile was 0.09 m. The simulation result found that an electromagnetic field was dispersed resulting in the highest electromagnetic fields at one point. The effects of the amount of induced voltage on the inverter damage was tested by the induced voltage impulse to 10/350 μS and 0.25/ 100 μS. The results showed that the size of the structure supporting the solar panel and the point of lightning current influenced the generation of induced voltage at the junction of the solar panels. The amount of induced voltage generated can be more accurate to determine the rating of the over voltage protection device.
