Sorry but KISS - Keep It Short & Simple applies to solar panels....building a solar panel into a roadway where it must support the weight of trucks, deal with abrasion/chemicals etc. not to mention they need to be highly transparent and angled facing the sun, It's tough enough to keep them woking on the roof of a building
