This solar boondogle will take 100 years to pay itself off -- if it lasts that long! Solar- and wind-power are only for environmentalists that can't or won't understand economics, math, or science and for remote off-the-grid sites. Another factor is the substantial toxic waste resulting from the manufacture of solar system components. All government subsidies of "alternative energy" scams such as solar and wind power and electric and hybrid cars must cease immediately.
