To complete the attached worksheet, including information on the identified states from the provided source as well as an estimate of the total number of owner-occupied, single-family homes in each state that have solar panels.
The estimated payback period for installing solar in Arizona is 11 years.
No sources specifically addressing the number of owner-occupied units that have solar panels installed were located. It was found that approximately 12% of single-family homes in Arizona had solar panels at the end of 2019. Since the majority of single-family homes (64.8%) in Arizona are owner-occupied, we assumed that the rate of solar installation on owner-occupied single-family homes was similar to the rate for all single-family homes and used the following formula to estimate the information for row 15: 1,257,000 x .12 = 150,840.
