Typically, consumers can expect to pay between $1,000 and $3,000 for the installation of a single large solar panel. This range reflects varying circumstances but generally encompasses panel placement, wiring, and electrical system connections. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. These benchmarks help measure progress toward goals for reducing solar electricity costs. . NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus-storage systems. Data source: IRENA (2025); Nemet (2009); Farmer and Lafond (2016) – Learn more about this data Note: Costs are expressed in constant 2024 US$ per watt. Unlike residential panels, commercial systems tend to be larger, with capacities ranging from tens of kilowatts (kW) to several megawatts (MW).
