He is not human though lol he is kryptonian his phisology is explained in great detail in the comics, him getting sun burned/ Tan is not compatible with it. The sun can destroy him if he gets too close, just like a battery too high a voltage can cause them to explode, just like superman's cells. His cells absorb too much energy and they become unstable and explode, but it was not burning him lol. See all star superman. The outside battery doesn't burn just like steel doesn't burn until exposed to great heats, its implosion from inside from too much power/energy
I'm thinking this statue isn't for you.
