Many homeowners wonder what will happen to their home’s property value if they add solar. A number of studies have looked at this question. The largest and most thorough to date was conducted by the Lawrence Berkeley National Lab and published in January 2015. It looked at data from eight states over a fifteen year time period. On average, home values increased by $4 per watt of installed solar capacity. One Solaflect PV Tracker has 4 kW (4,000 watts) of capacity. See the report here.
Note that in Vermont, state law exempts solar equipment from being assessed for property taxation, so long as the solar array is smaller than 50 kW in size (that is, fewer than 13 Solaflect PV Trackers).
In New Hampshire, each town has the option to exempt solar from property taxation. Details regarding the towns that have adopted an exemption are available here. New Hampshire residents interested in solar should contact their local government to confirm the exact details for their town.
