What returns can be expected from a PV system?
A. The initial pretax return for a medium-sized system on a good site is 8%-12% annually. That compares favorably to money market accounts, CD’s, stocks and even long term treasuries. Initial returns can range from 6%-12% depending on system size, site specifics and an investor’s tax bracket. The initial rate of return can be calculated by doing a solar site survey and system design before making a decision to purchase a system. Average system pay back is 9-11 years.
