I understand your point to their cosmetics but they are on the rear of our garage so no one can see them. We don't even notice they are there. To get 75% free electric is a great benefit though that cannot be ignored.
I suspect with Tesla roof tiles and the likes of new products coming there will be better products to alleviate these cosmetics.
Solar is the future ! Micro generation is the way forward.
Why Boris sees fit to plunge all our efforts into one thing, wind, defies logic or sense IMO....
