4 FAQs about US Solar Electric System

How much solar power does the US have in 2025?

Solar accounted for 58% of all new electricity-generating capacity added to the US grid through the third quarter of 2025, with more than 30 GW installed. Solar and storage, combined, accounted for 85% of new capacity in this timeframe. The US added 4.7 GW of solar module manufacturing capacity in Q3, bringing the total to 60.1 GW.

What percentage of US electricity is generated by solar?

Including that additional solar capacity would bring the share provided by solar + wind to more than a quarter of the US total. With the inclusion of hydropower (7.59%), biomass (1.06%), and geothermal (0.31%), renewables account for a 32.40% share of total US utility-scale generating capacity.

Is solar power a 'American energy dominance'?

In the topsy-turvy world of US energy policy, solar power has been pushed aside while other renewables — namely hydropower, biomass, and geothermal — have earned the support of President Donald Trump's “American Energy Dominance” program. That's just plain weird.

What percentage of US solar power is wind & solar?

Taken together, wind and solar make up 23.44% of the US's total available installed utility-scale generating capacity. Moreover, almost 29% of US solar capacity is in the form of small-scale (e.g., rooftop) systems that are not reflected in FERC's data.
