Environmental Considerations: 

• Solar energy does not generate greenhouse gas emissions (Zero Emission) while operating (however, emissions are created at different stages of solar energy cycle)

• A solar energy life cycle produces less carbon dioxide than natural gas and any non-renewable source.

​

Average Solar Payback period is 11.43 Years

Solar Panel Life Cycle is 25 Years.
