Hi, I had solar panels installed and all the electrics are in the garage. We are being driven mad by the 'pings and twangs' that are vibrating through the house throughout the day and night. It's like a massive elastic band being twanged. We did get the installers out and the said that yes sometimes you will get the vibration noise and we should consider 'boxing in' and insulating the box if we don't get used to it. It is impossible to get used to it. Unfortunately my installers have now gone bust! Visitors are now refusing to stay overnight!!! Please help, what can I do and can I do it myself?
