I have used my system without, and now with solar panels for a few years now. I don't notice any difference in sound quality and nothing noise inducing. I don't notice any problem with inverter noise either. Most solar panel systems don't have any battery storage devices that I am aware of. By law, in many areas, you also have to be hooked up to the electrical grid of your local power company along with your solar panels.
Solar Panel and Inverter Recent Audio Lessons Learned
I am building a new home in California with a dedicated upstairs music room. California requires 2020 new home construction be equipped with solar panels to augment conventional electric power. The solar panels will be installed on the roof and located in the area directly above the music room ceiling. I am concerned about adverse impacts (such as RFI) on sound reproduction. Does anybody have current experience on whether they have experienced negative sound impacts attributable to solar panel inverters and battery storage devices, or implementation of effective mitigation measures? [NOTE: I am a novice in the area of residential solar energy and reluctant to rely on "canned" solar provider internet sources. I am looking for real experiences from true audio and music enthusiasts.] Thanks for your assistance.
