Photovoltaic cost data between 1975 and 2003 has been taken from Nemet (2009), between 2004 and 2009 from Farmer & Lafond (2016), and since 2010 from IRENA. Prices from Nemet (2009) and Farmer & Lafond (2016) have been converted to 2024 US$ using the US GDP deflator, to account for the effects of inflation.
The total cost over the service life of the system is amortized to give a levelized cost per year. In the PV System Cost Model (PVSCM), the owner's overnight capital expense (cash cost) for an installed PV system is divided into eight categories, which are the same for the utility-scale, commercial, and residential PV market segments:
The representative residential PV system (RPV) for 2024 has a rating of 8 kW dc (the sum of the system's module ratings). Each module has an area (with frame) of 1.9 m 2 and a rated power of 400 watts, corresponding to an efficiency of 21.1%.
Market analysts routinely monitor and report the average cost of PV systems and components, but more detail is needed to understand the impact of recent and future technology developments on cost. Consequently, benchmark systems in the utility-scale, commercial, and residential PV market sectors are evaluated each year.
With the average residential solar system costing between $20,000 and $30,000 before incentives, and the federal 30% tax credit scheduled to step down after 2025, now is an optimal time
