The average cost of solar panels ranges from $2. 50 per watt installed, with most homeowners paying between $15,000 and $35,000 for a complete system before incentives. . This paper presents average values of levelized costs for new generation resources as represented in the National Energy Modeling System (NEMS) for our Annual Energy Outlook 2025 (AEO2025) Reference case. The estimates include only resources owned by the electric power sector, not those owned in. . The latest cost analysis from IRENA shows that renewables continued to represent the most cost-competitive source of new electricity generation in 2024. Total installed costs for renewable power decreased by more than 10% for all technologies between 2023 and 2024, except for offshore wind, where. . Average price of solar modules, expressed in US dollars per watt, adjusted for inflation. Data source: IRENA (2025); Nemet (2009); Farmer and Lafond (2016) – Learn more about this data Note: Costs are expressed in constant 2024 US$ per watt.
