Did I read that right? The director of the company that sold them and made false claims is now in the business of 'helping' people to claim against those who mis-sold solar panels?
In my opinion, having solar panels is no longer financially viable; especially since the feed in tariff was closed to new applicants from 1st April 2019 ....
Glad you didn't bother wasting your time and your money :)
On the other hand, we had solar panels fitted eight years ago and managed to get the full, index linked feed in tariff. We paid £10,000 for them and thus far have received over £ 7,000 back, as well as having reduced electricity bills. Another year, and they will have paid for themselves.
I am not gloating, just pointing out that once upon a time they were worth having. I wouldn't consider doing it now.
