Both are massively inefficient when compared to eating plants however you could not feed the current human population by hunting so hunters are almost entirely unjustified in saying that they need to hunt to sustain themselves. Hunt(or farm) some wheat instead, it complains less. Just thought of this, for a lot of crops you don't even need to kill them to obtain the food so yeah, don't eat animals.

I don't know if this is a joke or not. Regardless standing in the path of a solar panel would not cause any skin damage (other than what happens when you stand in the sun) because solar panels are designed specifically to absorb as much solar radiation as possible, a solar panel that reflected sunlight would be entirely worthless unless you wanted a tan.
