The U.S. solar panel manufacturing market isn’t the biggest in the world by any means, but it is growing. Many global names set up shop in the country in 2019 to help push the United States to bigger domestic capacity numbers. Here are the Top 10 largest solar panel assembly facilities in the United States based on megawatt capacity. All data is accurate as of Nov. 25, 2019.

They sold that off to raging wire for Data Comms by NTT. Now we’re hoping to hussle into the marketplace with our nano-processes to develop PV Panels, Batteries, and Grid-tie inverters.
I was always told the labor alone to produce cells here was not cost efficient. We hope to start our R&D solar cell production array and off-shore automated cell process line. The final assembly will be based out of New Mexico. We hope to have class-A cells available to commercial and consumer markets as we emerge with certified USA grade panels for solar farms and mini-grids in the future of 2020!

I believe the cells from any manufacturers extruding silicon into ribbons in the US would be considered US made cells; or at least US made wafers, if shipped outside the US for doping and further processing etc. Are there still any US based manufacturers using extrusion methods? And if so, at what scale and capacity do those manufacturers operate at with their US facilities?
I’m surprised to see Miasole’ and Mission Solar still on the list. They were early funded and were, (are?) gearing themselves towards the architectural solar PV aspect of building with solar PV. One of the early adopter CIGS manufacturers Nano solar, was building utility scale solar PV farms in Germany with solar PV panels “printed” onto aluminum substrate to create panels in a “roll to roll” process. No real word why this panel didn’t work out. Nano solar seemed to have almost the same business model as First Solar in Arizona.
Yes, MiaSole is involved with thin-film solar and has been transitioning to less traditional solar applications. Mission Solar is still going down the traditional ground/roof install route.
They may be made in the USA but are the cells made in the US too?
Many use parts from all over and just do final assembly in the US.
To my knowledge most are only assembled in the USA.
The only cells that are made in the United States are made by Panasonic at the Panasonic/Tesla plant in Buffalo, NY, as far as I know.
I started up what used to be the SolarWorld module facility in Hillsboro. I know that they grew and processed their own cells as of 2012.
