List of Solar Panel Manufacturers in the USA

List of Solar Panel Manufacturers in the USA

  • Post author:

The demand for quality solar panels is increasing every year across the world, including in the United States. Most of the globe’s solar panels are manufactured in East Asia. China has the majority of producers. In fact, the top 8 producers from the top 10 are Chinese. South Korean and other Asian companies follow Chinese.

Although the USA contributes less than 10% of the global production, it still has a meaningful number of manufacturers operating in the homeland. Here is a quick list of the top solar panel manufacturers in the USA:

  1. First Solar
  2. Tesla/SolarCity
  3. Hanwha Q CELLS
  4. LG Solar USA
  5. JinkoSolar
  6. Silfab Solar
  7. SunSpark USA
  8. Heliene
  9. Mission Solar
  10. MiaSolé
  11. SunPower
  12. Auxin Solar
  13. CertainTeed Solar

There are many reasons for consumers and solar contractors to choose American manufacturers rather than reply to some foreign companies. Perhaps, people want to support the nation’s employment and American companies. Another reason is domestic companies are more reliable and trustworthy, especially for solar contractors, since their entire business depends on manufacturers. Also, businesses remain secure from uncertainties, like import tariffs, for example, in January 2018, the US government imposed a 30% tariff on the import of solar panels and cells. Nevertheless, we have mentioned below a complete list of all major solar panel manufacturers in the USA.

Auxin Solar
