Not sure if it fits your theme, per se...
My first #Solar installation was with the panels mounted on an old chicken tractor that was no longer in use...
Eventually moved them onto some gate hinges hanging on a beam under the eaves on my #TinyHouse so I can angle them or put them down as needed, without having to invest in fancy roof mount hardware.
Building it on a "vehicle" rather than a "house" allows more flexibility for #DIY installations, not needing an inspection, etc.
