Here in Colorado, the typical price for a PV system is running about $2.80/watt. This breaks down to $0.70/watt for panels, $0.33/watt for inverters, leaving $1.77/watt for permitting/paperwork/design/inspection/labor.
From this you can see that the majority of the system cost is not the hardware but the soft costs. The portion of your original costs (more than 60%!) have no value for a future owner: they will have to pay again the (new) design costs, paperwork/inspections etc associated with the system re-installation, and of course the labor to install the panels at their new location.
This is a weakness of how solar is bought/sold in the US today, somewhat analogous to how cumbersome it used to be to get a house mortage. The internet in the form of (for example) Rocket Mortgage greatly streamlined the costs/time of getting a mortgage: the same thing is need for the solar industry to reduce the amount of stiction involved in acquisition. This would have to include integration with the local permitting authorities, which is probably why no one has tried to tackle this problem yet.
Wouldn't it be nice to go to a web page, type in a few details, electronic orders go out to contractor/local permitting department, crew shows up next day for installation, simple sign-off without inspection. Badda Bing!
dream on.

Subject: Sale of a third party solar system
I am the owner of a 26 KW pv system on a grocery coop, which I've owned for 5.5 years. I'm nearing the end of the depreciation period and i'm interested in assessing how much the system may be worth if I put it up for sale, either to the coop or others.
Has any one else sold a third party owned system or know of a published analysis?
I'm just starting my research on this question.
Thanks ,
