Solar costs have deflated by 70% in the past decade to $800/kW in 2025. 60% has been the scale-up to mass manufacturing, and 40% has been rising efficiency of solar modules. Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system. . The average cost of residential solar has decreased by about 69% since 2003. In 2004, solar panels cost $10. 70 per watt and were about 15% efficient. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U.
