Hal Bernton interviewed Jeremy and Pam for the Sept. 7th segment in his Seattle Times series dealing with responses to climate change.  There is a discussion of solar energy systems that are leased to utility customers by a third party such as SolarCity. Companies that lease solar like to point out that the expansion of the solar market has been propelled by third party-owned projects, and that is true to an extent.  It is also true that for a few years there weren't many sources for financing solar, so leasing was one of the only ways to reduce the upfront cost.  Now that excellent financing is available the need for third party leasing has ebbed.
Here is a little more about Solar Leasing and Washington state incentives…
Because of that last point, we continue to keep the door open to the possibility of solar that is owned by a third party, but the current state program fund is insufficient to support the addition of leased projects without  causing a reduced incentive for those who are already in the program. The accompanying Sankey charts show how the financial values flow in a system purchase versus a system lease.  As you can see, there is a clear advantage with ownership, but there is still a place for leasing; the challenge is to find additional incentives that will support third party ownership. (Key to abbreviations: NEM=net metering; TPO=third party owned; ITC=investment tax credit).
