Solar Panels and Embodied Energy

A commonly asked question about solar panels is "How long does it take to make back the energy used in the manufacture of the panel?" This energy (otherwise known as embodied energy) is produced by a Siemens panel in about 18 months. So that gives another 23.5 years of free electricity before the warranty even runs out! Other brands of solar panels would have similar amounts of embodied energy.
