Anybody have experience buying into a solar farm for home electricity? [View all]

Tomorrow we're getting a proposal from a solar farm in an adjacent town. We heat, cook and heat water with natural gas so our electric bill is only about 40-50 dollars per mo. Apparently the deal is you rent-to-own the solar panels at the farm.

Just wondering what others have learned. We live in MA, so I think the state might give a tax break for solar.
