Solar ERoEI Is Actually Really, Really Good

The terms “energy payback” and “energy payback period” when used to discuss solar power might be kind of confusing at first glance, but when you dig a little deeper, you get much more clarity. Energy payback refers to the amount of energy a solar power system has to make in order to equal the energy which was used to produce it.
