How solar has exploded in the US in just a year – in numbers

Author: Michelle Lewis


Solar and storage companies have announced over $100 billion in private sector investments in the US since the passage of the Inflation Reduction Act (IRA) a year ago, according to a ( by the Solar Energy Industries Association (SEIA) (

Since President Joe Biden signed the IRA in August 2022, 51 solar factories have been announced or expanded in the US.

These new and expanded factories will invest nearly $20 billion into US communities and amount to 155 gigawatts (GW) of new production capacity across the solar supply chain. These announcements include 85 GW of solar panel capacity, 43 GW of solar cells, 20 GW of silicon ingots and wafers, and 7 GW of inverter capacity:

Solar factories announced in the last year are going to employ more than 20,000 Americans.

By 2026, the US will have over 17 times its current manufacturing capacity across modules, cells, wafers, ingots, and inverters when these announced factories are online – and that’s enough to supply the majority of solar projects expected to be built in the US.
