Solar power in car parks

Put solar panels on top of trolley parks in supermarket car parks or even on canopies in car parks. If they were on canopies in car parks, it would mean that solar power is being generated and cars would also be keeping cooler in the shade of the canopies, therefore reducing the need for air conditioning to be put on in an extremely hot car which has been sitting in the direct sunlight. Electric cars can be charged and the stored power can go to lighting the car parks and surrounding areas or buildings.
