Environmentally how long does it take to be energy neutral from the production of a solar panel?
For solar panels to be able to be called a renewable energy source the energy that they produce needs to be reimburse from the manufacturing process. In mid 2006 , many years ago the International Energy agency concluded that to recover all the energy used in the manufacturing of and recycling of solar panels would take 16- to 1.8 years. Over the past 10 years manufacturing practices has reduced this time frame even more. If you factor in that solar panels should last around 25 to 30 years a solar panel has the capacity to produce 15 times that amount of energy that it cost to produce the same panel.
