To reflect this difference, we report a weighted average cost for both wind and solar PV, based on the regional cost factors assumed for these technologies in AEO2023 and the actual regional distribution of the builds that occurred in 2021 (Table 1).
Cost per kWh shows the lifetime cost of solar electricity by dividing your net system cost by total expected energy production over 25 years. This typically ranges from 6-8 cents per kWh, compared to current grid electricity averaging 16.44 cents per kWh nationally.
This is because more hours of operation spread the fixed capital costs over increased electricity production, reducing the levelized cost of electricity (LCoE). Capacity factors are determined by properties of the solar resource including the direct normal irradiance (DNI) and daily/seasonal profile, power block reliability, and inclusion of TES.
Despite these cost increases, advancements in solar PV technology and construction continue to provide downward pressure on the $/kW cost.
Projections of utility-scale PV plant CAPEX for 2035 are based on bottom-up cost modeling, with 2023 values from (Ramasamy et al., 2023) and a straight-line change in price in the intermediate years
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are

Historic Low Pricing: Solar costs have reached unprecedented lows in 2025, with systems ranging from $2.50-$3.50 per watt installed, making the technology more accessible than ever before.
Lawrence Berkeley National Laboratory compiled and synthesized empirical data on the U.S. utility-scale solar sector.
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
NLR''s bottom-up cost modeling methodology, shown here for residential PV systems, considers a wide set of factors and many interactions between them. These bottom-up models
Installation costs for CSP declined by 50 % over the past decade, falling to the current range of $3000–11000 per kW. Adding 6–15 h of thermal energy storage at $20–60 per kW is now
