the picture is correct, there's a common post that does the rounds every now and again that says we should put solar panels over car parks instead of building dedicated solar farms, this image provides reasoning as to why dedicated solar farms are a good option, while also recognizing that solar panels over car parks also have their place

my personal opinion on this is, new solar panels should be installed in dedicated sun-tracking solar farms, and older/recycled panels are ideal for car parks, flat roofs, etc.
