Break even at $1 per watt would be 3 years
Today, I pay 11 cents per kilowatt-hour from Xcel Energy. At $1 per watt, a solar panel rated at 1000 watts would cost $1000. It would take 9000 hours of use to break even. Assuming an average of 8 hours of sunlight per day, that would take 3 years.

At the current price of $8 per watt, the break even point is 24 years. Even $3 per watt isn't attractive with a break even point of 9 years.
