Many of our customers get this question from their environmentally conscientious friends: How much energy does it take to manufacture solar panels compared to how much energy they produce? Good question!
The Institute of Science in Society has an answer: The Institute’s life cycle analysis shows that the energy payback for polycrystalline panels (which is what Sungevity uses) is 2.2 years. In other words, after 2.2 years, the power generated by the panels exceeds the power used to manufacture them. The panels have a lifespan of at least 25 years which means 23 years of clean, green energy on your roof. That’s a fantastic energy payback by any standard and makes us doubly confident that solar is the single best way to go green.
