Actually a good online resource for sizing, estimating and getting
installers for solar systems is  www.findsolar.com . They have a
property value calculator as well. Hires an excerpt from it:
 
How do you calculate the increase in property value? 

We assume installing solar energy systems will increase the value of
your property. In many states this increase in value is exempt from
property tax. 

How much your property appreciates depends upon many factors. For our
calculations we have assumed the value of your property will increase
by:

*	Solar Electric (PV): Twenty times (20x) your 1st-year utility
savings. (So Brian this matches your estimate) 
*	Solar Thermal (water, pool, spa): Fifteen times (15x) your
first-year utility savings.

Actual situations will vary.

Annual savings from a solar system should appreciate for the first 10-15
years for PV (about 10 years for solar thermal), in line with utility
rate inflation. After that, the savings may start to diminish as the
solar system nears its end of life.

Here's another paper they reference:

Hope this helps.

Subject: [BLDG-SIM] property values and solar energy



Anyone have information on property value increases for including/adding
solar energy (photovoltaics, and or hot water) to residential and/or
commercial buildings.

 

There is a reference out there to the Appraisal Journal saying 1$
reduction in utility bills equals $20 in increased property values.  But
this is for conventional conservation improvements for residential.
Does it apply to solar energy generation?
