Solar cost update 2025: CAPEX, O&M, LCOE, payback math
Explore solar costs in 2025, including CAPEX, O&M, LCOE, and payback periods. Discover how integrated solar and energy storage solutions enhance investment returns and energy
In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power. It also helps them handle money risks.
Battery storage prices have gone down a lot since 2010. In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power.
We expect this trend will continue in 2025, with 32.5 GW of new utility-scale solar capacity to be added. Texas (11.6 GW) and California (2.9 GW) will account for almost half of the new utility-scale solar capacity addition in 2025.
As can be seen in the chart below, the ITC brings down the cost significantly, with 100MW, 4-hour utility-scale standalone energy storage ranging from US$83/MWh if deployed in areas designated as 'energy communities' (regions with economies historically dependent on coal and other conventional energy technologies) up to US$192/MWh at the top end.
