Does the production of solar panels require more energy than the panels will produce in their lifetime? That’s a question you may hear now and again, especially when talking to those who aren’t really on board with this whole clean energy idea. So, time to set the record straight. There’s a great article over at Care2.com that addresses just this subject. The bottom line is that depending on what technology of panel you’re talking about, the energy payback point (they’ve produced as much energy as it took to manufacture the panel) is from one to four years. Check out the full link above if you want all the details.
