It depends on how much power you use. An easy way to figure it out is first to figure how much you used monthly on average before you got you solar system, and then figure out the average of what you pay now. The difference between these two prices is what you’re saving with your solar system. Then, divide the cost of the solar system by how much you save each month, and you will get the number of months that it will take to pay it back, like, for instance:
200 (average pre solar) – 150 (average post solar) = 50 (difference in cost)
500 (cost of solar installation) / 50 (difference in cost) = 10 (months to pay it back)
Hope this helps!
