While the solar trackers do produce a small amount of sound the main source of sound in a solar facility are the inverters. These devices convert DC power to AC power and are best described as making a humming-type sound. We expect the sound pressure of our inverters to be 55dB at 50 meters. (At the fence line, sound from this project will be significantly less than the county recommended limit, which is 67 dBA).
As you can see from the graph below, the project’s sound level equates to that of normal conversation. Since our inverters are all interior to the project, we expect little to no sound to travel beyond the project area.
