be terrific.
I'm not sure about the numbers in this OP: $107,900 would buy about 20-25 kW system, not nearly enough to offset the Whitehouse by 81% I suspect.
In any case, this is great news and I hope he goes for it.
Now about those Carter "solar panels":
Carter had solar thermal water heating panels, not photovoltaic, just to correct any misunderstandings about the panels.
Lot's of solar on the whitehouse grounds today:

Solar at the White House
Solar energy has returned to the White House complex. While the White House has kept pretty quiet about it, three solar installations were completed last summer on White House buildings and are now generating renewable power and hot water. Here are the details:

Installing PV panels on a National Park Service maintenance building at the White House.
In July and August, three solar energy systems, designed by Steven Strong of Solar Design Associates in Harvard, Massachusetts, were installed on two separate White House buildings. The first of these, a large 8.75 peak-kilowatt photovoltaic (PV) system, was installed on the National Park Service maintenance building located in the southwest corner of the 16-acre (6.5 ha) White House grounds. This system consists of 167 EC-51 PV modules, each rated at 51 watts, manufactured by Evergreen Solar of Marlboro, Massachusetts. Three 2,500-watt Sunny Boy inverters, provided by SMA Americas (a division of the German manufacturer SMA), convert this DC electricity into AC power that is fed into the White House electricity grid.
On the same building, a residential-scale solar water heating system was installed to provide hot water for landscape maintenance personnel. This system is comprised of two 4' x 8' (1.2 x 2.4 m) flat-plate collectors made by SunEarth, Inc., of Ontario, California. These panels were installed using a typical stand-off mount in a drain-back configuration (for more on solar water heating.
The third installation is a five-panel, building-integrated solar hot water system on the White House cabana next to the presidential pool and spa. This system is integrated into a terne-coated, standing-seam copper roof. The inset design of the panels provides a relatively flush profile (see photo). Hot water produced by this system heats a hot tub and shower, with any extra energy going into the outdoor pool. The absorber plates for these panels were made by SunEarth, but the rest of the system was site-manufactured for better integration with the roof.
