Generally speaking, the cost of solar panel installations varies by state but has been steadily coming down over the last several decades.

A solar panel system costs a little high, but can save that much and more over its lifetime.

Installation cost is dependent on a number of factors besides the basic cost of solar modules. The rising price of things like labor, administrative costs, wiring and other components actually drove the average price of solar installations up between 2022 and 2023, although there's some indication prices are already coming down again.

Still, there can be a lot of variation in pricing from market to market, in different states offering different incentives and labor and permitting costs.
