US Solar Power Leads New Electricity Additions in 2025 with 43 GW Capacity
In 2025, the US installed 43 GW of solar capacity, making it the largest source of new electricity for the fifth year. According to the SEIA and Wood Mackenzie, solar and energy storage comprised 79% of all new capacity, with significant installations in Texas and Indiana. Despite regulatory challenges, the solar sector remains economically viable, driven by rising electricity demand. Projections indicate an addition of 490 GW by 2036, reaching nearly 770 GW total capacity. Domestic solar manufacturing also saw substantial growth in 2025.

In 2025, the United States installed 43 GW of new solar capacity, maintaining its status as the largest source of new electricity additions for the fifth consecutive year. Solar and energy storage accounted for 79% of new electricity generation capacity, with significant contributions from Texas (11 GW) and Indiana (3 GW).
Despite regulatory challenges, the solar sector remains robust, driven by increasing electricity demand from data centers. Projections suggest the US could add 490 GW of solar capacity by 2036, reaching a total of nearly 770 GW. The US also saw a surge in domestic solar manufacturing, with module capacity increasing by over 50% to 65.5 GW.
