They are in front of the elevators at an outdoor multi story parking garage around my area. That’s all I wanted to share, thanks.

Hm, the efficiency point is a bit moot, you can say the same for coal, oil and gas.
You definitely cannot. All of those materials burn and release carbon. Not 100% of the material goes towards energy. Solar for instance produces electricity with no byproduct (excluding the cost to make the panel). There are no byproducts in the generation stage. We then transport the electric which also produces heat.
