Solar panels.

I'll look the paperwork out, but I'm pretty sure the panels are now registered with our property with the land registry, like go with (joined) to the property

That's 100% how these schemes work. They don't care who owns the property as the new owner is legally bound to keep the panels connected (or buy the system from them).
