No it's not dubious at all. It's hilariously beneficial considering how far north we are, where I honestly thought it would be very borderline, and probably not worth it at all.
We just about eliminated the electricity component of the typical UK supply of electricity and gas for heating. That's not net zero, or creative accounting, that's actually eliminate use of grid electric for nine or ten months, with a little use in winter. That only because of switching water heating to the panels, that was previously on gas. We're in N Cumbria.
