First Solar
Ohio-based First Solar is the largest manufacturer of solar panels in the U.S., producing about 50% more panels than the next-biggest American-made brand. The company mainly produces panels for commercial or industrial-scale installations, which means the individual panels are less efficient than those typically used on residential rooftops, where the goal is to place as much capacity as possible in the limited available space.
Qcells
Qcells is the second-largest manufacturer of solar panels in the U.S., the second most-popular brand on the EnergySage marketplace, and one of the most popular residential solar panel manufacturers, American-made or otherwise.
While Qcells is based in South Korea, the company recently opened a solar panel manufacturing plant in Georgia. Although not all of their panels are American-made (at least, not yet), you&#;ll still be supporting American manufacturing by choosing Qcells.

Here's the full list, according to the DOE, as of July :
The U.S. Solar Photovoltaic Manufacturing Map shows only active manufacturing sites that contribute to the solar photovoltaic supply chain. It details their nameplate capacities, or the full amount of potential output at an existing facility, where known. This does not imply that these facilities produced the amount listed. The data for this map is gathered from public sources and through direct communication with producers. This data is subject to change and is for general informational purposes only. The Solar Energy Technologies Office (SETO) does not guarantee that the data is complete or free of error. If you would like to submit a comment, correction, or provide the information for a facility to be included on the map, contact us.
Key: ac = alternating current, CdTe = cadmium telluride, c-Si = crystalline silicon, dc = direct current, E-BOS = electrical balance-of-system, GW = gigawatt , HQ = headquarters, kt = kilotonne, MW = megawatt, S-BOS = structural balance-of-system, W = watt, and yr = year.
