Repurposed 330 gallon Tote transport Tank (expired DOT cert) into a high tech rabbit hutch

I got a bunch of these old sulfuric acid IBC tote tanks from my work .
This is my rabbit hutch prototype I created from one of the tote tanks..
It has two used solar panels as a roof so once I create more of these modular animal cages I can line them up and use them as my solar array for some high-tech free power gardening including off-grid daylight timers for chickens and brooder warmers and automated chicken run doors, and power for security cameras
