About Solar power generation costs in 2025
All technologies demonstrate some degree of variability in cost, based on project size, location, and access to key infrastructure (such as grid interconnections, fuel supply, and transportation). For wind and solar PV, in particular, the cost favorability of the lowest-cost regions compound the underlying variability in regional cost and .

U.S. solar generation grows in the forecast by 34% in 2024 and 31% in 2025. Rising solar generation also cuts into natural gas generation next year. Solar generating capacity is growing fastest in Texas along with associated battery storage projects.
The global weighted average cost of electricity could fall by 26% from onshore wind, by 35% from offshore wind, by at least 37% from concentrating solar power (CSP) technologies, and by 59% from solar photovoltaics (PV) by 2025, the report finds.
Cumulative power system costs from 2020 to 2050 are $562 billion (25%) higher, which includes the costs of serving electrified loads previously powered through direct fuel combustion. However, avoided climate damages and improved air quality more than offset those additional costs, resulting in net savings of $1.7 trillion.
Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.
As the photovoltaic (PV) industry continues to evolve, advancements in Solar power generation costs in 2025 have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Solar power generation costs in 2025]
Are solar PV projects reducing the cost of electricity in 2022?
Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.
How much energy will solar provide by 2050?
Solar will provide 30% of buildings’ energy, 14% of transportation energy, and 8% of industrial energy by 2050, through electrification of these sectors. To achieve 95% grid decarbonization by 2035, the United States must install 30 GWAC of solar each year between now and 2025 and ramp up to 60 GWAC per year from 2025 to 2030.
What is the largest source of electricity generation in 2025?
In 2025, renewables surpass coal to become the largest source of electricity generation. Wind and solar PV each surpass nuclear electricity generation in 2025 and 2026 respectively. In 2028, renewable energy sources account for over 42% of global electricity generation, with the share of wind and solar PV doubling to 25%.
Will solar be the fastest growing source of electricity in 2024 and 2025?
Electricity generation New solar photovoltaic power projects are driving our forecast that solar will be the fastest-growing source of electricity in 2024 and 2025. We expect that the share of total U.S. electricity generation from solar will grow from 4% in 2023 to 5% in 2024 and to 7% in 2025.
How much solar will be deployed in 2025?
To reach these levels, solar deployment will need to grow by an average of 30 gigawatts alternating current (GW ac) each year between now and 2025 and ramp up to 60 GW per year between 2025 and 2030—four times its current deployment rate—to total 1,000 GWac of solar deployed by 2035.
Will solar power grow by 2035?
Under this scenario, solar will grow from 3% of the U.S. electricity supply in 2020 to 40% by 2035 and 45% by 2050. To achieve 95% grid decarbonization by 2035, the United States must install 30 gigawatts AC (GW AC) of solar photovoltaics (PV) each year between 2021 and 2025 and ramp up to 60 GW AC per year from 2025–2030.
