Is our list missing any U.S. companies? Leave us a note in the commentswe’ll update with new additions as they come in.

There are two things we should mention regarding our list of solar panel manufacturers based in the United States.

To begin with, many of these firms construct part or all of their solar panels in the United States, but import crucial components from other nations. These components are likewise subject to the solar tariff, however the first 2.5 gigawatts (GW) of solar cells imported each year are exempt. (For comparison, the United States deployed 12 GW of solar in 2017, including an estimated 2.5 GW of solar panels made in the United States.)

Second, not all of the companies on this list are based in the United States. Some, like Heliene, have headquarters elsewhere. SolarWorld Americas, for example, is a subsidiary of a foreign manufacturer. They all, however, make some of their panels in the United States.

Continue reading to learn more about some of the companies that manufacture solar panels in the United States.

SolarWorld Americas and Suniva

January 2019 update: Suniva declared bankruptcy in 2018 and is currently undergoing the bankruptcy process.

These two may be the most recognizable of all the U.S. solar panel manufacturers on the list (and no longer on the list). SolarWorld Americas and Suniva have both recently been in the headlines as two companies that have petitioned the government to levy taxes on foreign solar panel manufacturers.

In the solar business, there is debate regarding whether the tariffs will truly stimulate greater manufacturing in the US in the long run. According to certain industry associations, the rising costs will have a negative influence on solar in the United States. According to the Solar Energy Industries Association, there will be modest job growth in manufacturing, but job losses in the solar installation industry will be far greater.

SolarWorld has stated that it would expand its solar panel production in the United States in the near future. Suniva hasn’t made any public statements about their plans.

Heliene Solar

Heliene is headquartered in Sault St. Marie, Ontario, and produces the majority of its solar panels there. Heliene does, however, have a production facility in Minnesota. The Made in Minnesota Solar Incentive Program, which offers a cash payout to Minnesota solar system owners who install solar panels made in the state, accepts the company’s solar panels.

Heliene indicated that it will invest in a new equipment line at its Minnesota facility after the White House’s announcement of the solar tax.

Mission Solar

Mission Solar is situated in San Antonio, Texas, and all of their solar panels are designed, engineered, and assembled there. They create solar panels for both small-scale (rooftop) and large-scale (ground) installations.

Mission Solar, like the other companies on this list, announced that output would increase in 2018. Their plans, however, have been in the works since 2017 as a result of increasing output and are unrelated to the trade dispute.


Seraphim Solar USA is a wholly owned subsidiary of the Chinese Seraphim Energy Group. At its factory in Jackson, Mississippi, Seraphim Solar USA manufactures all of its panels in the United States.


Solaria is headquartered in Fremont, California, and its solar panels are made in both the United States and South Korea. Solaria reported in early January 2018 (before to the final tariff ruling) that it had raised $23 million to enhance its production capacity.

SolarTech Universal

SolarTech Universal is a solar panel manufacturer based in the United States. It owns its manufacturing facilities in Riviera Beach, Florida, and is the sole solar panel manufacturer in the state. The corporation believes that the tariff will have a favorable impact on its business in the short term, but that the expenses will outweigh the advantages in the long run.

SunSpark Technology

The parent company of SunSpark Technology is situated in China, and the firm is based in Riverside, California. SunSpark, which has a manufacturing site in Riverside, has been silent about the levy.


Tesla Energy has partnered with Panasonic to manufacture solar panels in the United States at the Tesla Gigafactory 2 in Buffalo, New York. Panasonic stated in early January 2018 that it has begun producing solar cells at the factory, both for the Tesla solar roof and for Panasonic solar panels.

Panasonic produces the majority of its panels in other countries, and it has so far been unable to meet all of Tesla Energy’s needs. Panasonic and Tesla, on the other hand, intend to increase output in the coming year. Tesla expressed its opposition to the tariff in the summer of 2017, and after the levy was announced, it reaffirmed its commitment to American manufacturing.

How many solar panel manufacturers are there in the United States?

The bulk of photovoltaic solar panels marketed in the United States were not built in the United States until recently. Several Asian solar companies, most notably in China, have begun to relocate their operations and manufacture solar panels in the United States.

Why? Because of the Trump administration’s import tariffs, which hit solar panels and manufacturing supplies in 2018. To encourage domestic production, then-President Donald Trump imposed a 30% tariff on imported solar panels and the cells required to make them. As a result, some solar energy companies have begun to manufacture at new facilities in the United States. The taxes on imported solar equipment were then extended for another four years by President Biden in February 2022.

Many of the main solar brands available in the United States are represented on this list, including Hanwha Q CELLS, Jinko Solar, Silfab Solar, Mission Solar Energy, and Solaria.

Here’s a list of the top five solar panel manufacturers in the United States.

Who is the world’s largest solar panel manufacturer?

#1 JinkoSolar Holding Co. is a company that specializes in solar energy. JinkoSolar is a Chinese conglomerate that manufactures solar cells, modules, and other solar-related materials. It is one among the world’s top solar panel producers in terms of delivered gigawatts (GW).

Who creates Tesla’s solar panels?

Tesla’s energy division is discreetly unveiling a new solar module for its solar rooftop business while Elon Musk goes on trial in Delaware for Tesla’s acquisition of SolarCity.

While the solar roof tiles have received the most attention, Tesla’s solar panels remain account for the majority of the company’s solar revenue.

Tesla has been overhauling its solar panel operations for some years, and it has lately begun to pay off, with the division returning to growth in recent quarters.

Tesla unveiled a new solar panel and cut solar retrofit prices about this time last year.

Tesla Solar became incredibly competitive with the new pricing and a new price match policy, and the business ramped up installations to 92 MW deployed last quarter.

Tesla is releasing a new solar panel, the Tesla T420S photovoltaic module, once again.

The solar panel configurator on the automaker’s website has yet to be updated. The company’s 340-watt solar panel maker, Hanwha Solar, is still the only one included.

The new Tesla solar panel looks like this:

How many solar panels are created in the United States?

According to the National Renewable Energy Laboratory, since 2004, U.S. output of photovoltaic cells used in solar panels has dropped from 13% to less than 1% of world supply, while China’s share has risen from less than 1% to 67 percent (NREL).

Does Tesla produce its own solar panels?

In addition to their popular Solar Roof which replaces traditional roofing materials with small photovoltaic shingles, Tesla also manufactures traditional solar panels..

Where do the majority of solar panels come from?

  • LONGi Solar, Tongwei Solar, and JA Solar are the top three global manufacturers.
  • The majority of solar panels are made in China, although certain companies in Canada and the United States are gaining ground.
  • LG Solar, CertainTeed, Q CELLS, Silfab Solar, JinkoSolar, Solaria, and Tesla are just a few of the well-known solar panel manufacturers with manufacturing sites in the United States.
  • While the place of manufacture may be relevant to you, you should also consider pricing, efficiency, brand, quality, and other considerations.

Who is the owner of Sunrun?

Sunrun is now the nation’s biggest dedicated home solar, storage, and energy services company, with over 3,000 workers servicing more than 134,000 families in 22 states under the leadership of Executive Chairman and co-founder Ed Fenster and CEO and co-founder Lynn Jurich (and counting).
