I think it might be time to look again? Cost of panels is extraordinarily low and cost of installation (e.g humans) is not on a similar curve. I looked at price/watt and went ahead and installed. The payoff period is ~11 years, 1 1/2 years in. Warranted to 20. You could take panel price to zero and it wouldn't have changed the math much.
