It’s fairly well-known that US rooftop solar costs have been going down rapidly year on year. Up to a certain point, this phenomenon was largely due to continual reduction in the price of solar panel modules. But that is not the case today… the major cause for the downward trend in rooftop solar costs is the fall in installation costs, financing, etc.
To understand this graphically, look at this chart from GTM Research :
