U.S. surpasses 50 GW of solar module manufacturing capacity
These investments will bring the total planned capacity of solar modules to over 50 GW, solar cells to 56 GW, wafers to 24 GW and ingots to 13 GW. Growth is seen further
As of Q1 2025, the Clean Investment Monitor tracks 110 operational solar component manufacturing projects across the US with the capacity to produce 42 gigawatts (GW) of modules, 8 GW of cells, and 26 GW of polysilicon. As those existing facilities ramp up production, an additional 19 GW module and 6 GW cell capacity will come online (Figure 3).
The Major Solar Projects List is a database of all ground-mounted solar projects, 1 MW and above, that are either operating, under construction or under development. The list is for informational purposes only, reflecting projects and completed milestones in the public domain.
There are more than 8,100 major solar projects currently in the database, representing over 340 GWdc of capacity. There are over 1,300 major energy storage projects currently in the database, representing more than 104,000 MWh of capacity. The list shows that there are more than 180 GWdc of major solar projects currently operating.
There remains an enormous amount of capacity in the pipeline, with more than 160 GWdc of large-scale solar projects either under construction or under development. The Major Solar Projects List is a database of all ground-mounted solar projects, 1 MW and above, that are either operating, under construction or under development.
