A few weeks ago DH and I started to hear a strange low muffled tapping/vibrating noise when in our upstairs bedroom. Sometimes it is intermittent, running for a few minutes then stopping and then starting again. Sometimes it is more constant.
We hear it later at night when upstairs (9pm onwards) and early morning (5am onwards) and sometimes through the night even. We can’t hear it when downstairs at all. The noise started just after our neighbour had solar panels fitted.
In 18 months of living here we never heard the noise before. We have checked our property/roof and it is not us! When raised with the neighbour he was quite cagey and denied all knowledge. He even denied hearing any noise in his own property which we find very hard to believe.
After politely raising this, the noise stopped for a few nights before starting again. This makes us more suspicious! Could the noise be connected to the solar panels?
Has anyone had a similar problem or had solar panels fitted themselves and noticed a noise/problem? We read something about solar panels requiring an ‘invertor’ and don’t know if this could be the cause. It sounds like the noise is coming from their loft.
It’s starting to drive us slightly nuts and neighbour is being unhelpful so any insights into cause and even who we might take this further with (local council?) would be most welcome.
