What better way to use solar panels that as a shading mechanism? The South Korean government had a great idea and ran with it, building a 20 mile stretch of solar bikeway, from Daejeon to Sejong. The lane is protected from traffic on both sides and is in an area about 100 miles south of the capital of Seoul.
One drone operater captured some awesome footage, strafing overhead the path. The audio is loud, as it's just the drone's engine, but turn down the sound and turn up some music to enjoy this footage
