I thought about it too, but still at the early stage. my electricity bill was $158 for 1230 kWh last month, roughly 13c/kWh. this includes ~$30 from my pool pump, ~$30 to charge my volt, ~$30 from the dehumidifier. 1/3 of the bill was from the distribution charge: 5c/kWh. I just switched to a time-of-use plan, which gives me 1.5c/kWh distribution charge for 7pm- noon next day. with this change, I expect to drop my bill by ~20%. so, even without solar panels, my cost is not too bad. but self-sufficient in energy does seem to be a cool idea. if I do want to generate 800kWh/mo electricity as my monthly average, I need about 17 of 300W panels, calculated by 800kW/300W/200 hours full sun light hours in MA/0.8 to account for efficiency loss [2]. The cheapest panels on [ 1] will cost me ~$3200 total before installation. If the cost is half of this number, I would attempt to do it now. At this point, I will watch and wait.
