Embedded Energy – Solar Module Manufacturing and Pay Back

Embedded Energy - Solar Module ManufacturingOne often stated myth is that manufacturing solar panels requires more energy than the solar module will produce is simply not true.

According to a 2004 National Renewable Energy Laboratory study that analyzes several different panel technologies, “Producing electricity with photovoltaics (PV) emits no pollution, produces no greenhouse gases, and uses no finite fossil fuel resources.” and it takes only 1 – 4 years for the energy savings accumulated by producing electricity from solar to equal the energy cost of producing the panel.

Solar technology has improved in the years since this study was conducted, and production efficiencies have driven the “energy payback period” down even further.  Solar modules generally have a 25 year warranty and can continue to produce long after that time frame(at a slightly reduced rate) lifetime production of a solar module exceeds far embedded costs.
