Well its not silent those panels go into MPPTs that produce noise when high amps are flowing through them to charge batteries if they don't direct export , if they direct export then there is noise from inverters to convert DC->AC

But is it honestly enough to notice if you live half a mile a way? Couldn't they just put up sound damping like the oil rigs do?

Well depends on where they are they might be obligated to put due to some noise polution law or they might not care because there is no such law
