How many dollars would 1 kilowatt make, concerning electricity made by a solar panel?

I would like to be able to calculate how much money I will receive from my power company if I were to make a solar panel and install it for my home and then sell the extra energy it generates back to the power company. I'm looking at my power bill and it seems that what I need to know to calculate this is how much would the power company pay me on a per watt basis.

Not everyone is going to have the same answer because different power companies will pay a different rate. Looking at my bill, I am being charged about 21 cents per kilowatt hour. One kilowatt hour is 1,000 watts per hour. So for every hour you send 1 watt back to the power company, you get 21 / 1000 = $0.021. But not really. What power companies do is to give you credit for what the power costs them only. Using the math above, I found that my power company pays me only 4 cents per kilowatt hour.

On average, you want to make a solar panel system that generates 12,000 KwH per year. To find out how many solar panels you need to buy to achieve this, here is the formula. If you live in California where you have about 8 hours of sunlight a day, then the math is 12,000 / 365.25 days = 32.8542 / 8 = 4.1 Kilowatt of solar panels. So in this case you want to make a 4 Kilowatt solar panel system. This means that if you buy a 120 watt solar panel, you would need 4,000 / 120 = 33 solar panels on your roof.

My friend John has 72 panels on his roof, here is a picture of his house.
