Yeah, lots of cost and fitting issues with them at the moment still, lots of new build companies can’t get the skilled labour to even build a straight gable end or fit a wet room, so vaguely ‘challenging’ technology that your average builder can’t do in his sleep is a not on their shopping list.
As the demand goes up they’ll start offering normal panels as an upgrade though. Knowing what the average new build buyer is like though, that demand will be slow, for a lot of them aesthetic is key too.
