Solar panels can lower your electricity bill by 75% or more, but the upfront investment is significant. Most homeowners spend between $12,600 and $33,376 to install a complete residential solar system in 2026, with the national average at $19,873 before incentives. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. Data source: IRENA (2025); Nemet (2009); Farmer and Lafond (2016) – Learn more about this data Note: Costs are expressed in constant 2024 US$ per watt. This work has grown to include cost models for solar-plus-storage systems.
