Solar Power Noise and Dust: For the Record
For example, a solar farm operating in a quiet rural town can have a background sound level as low as 25 to 30 dBA. In Massachusetts, the sound level limit may then be 35 to 40 dBA. Achieving 35 dBA sound limit will have some challenges. How is this tonal sound produced? Let''s start at the solar panels (also called PV modules).
