What is the life cycle for solar systems, and the approximate payback period?* Most manufacturers will offer a degradation rate warranty for a 25 year period. It is common to have 90% minimum rated power output in the first ten, years and 80% minimum rated power output for the remaining 15 year balance. Installations today generally achieve a payback period of seven to 12 years, after taking advantage of multiple incentives and funding. Some states offer better incentive packages than others, so this payback period will fluctuate accordingly. * Federal, State, and Local codes govern most of these requirements and should be thoroughly investigated. Data presented herein should be considered guidelines only. For more specific information, please contact TimHaahs via email at info@TimHaahs.com |
