Home solar and/or wind power, how long to break even point?

Do any of you reading this have a solar system and/or mini windmill setup for your home?
If so, how long do you expect it to take before you reach the break-even point?
A few years back I calculated the cost for where I live (with various government rebates, etc) and it would have taken between 6-7 years to recoup. Without the government incentives it would take probably twice as long.
One day, when I am no longer renting, I plan to make an attempt at becoming fully or very close to fully energy independent with solar, wind and whatever other methods are available to me.
