90 per watt without labor and other fees. Since your typical solar panel system size is 6. 5 kW, anticipate spending around $3,900 for the panels alone, or somewhere between $1,950 and $5,900. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. These benchmarks help measure progress toward goals for reducing solar electricity costs. . NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. NLR's PV cost benchmarking work uses a bottom-up. . 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. The Base Year estimates rely on modeled capital expenditures (CAPEX) and operation and maintenance (O&M) cost estimates benchmarked with industry and historical data.
