Top 20 Solar Panel Manufacturers in the U.S.

As solar installers, you would, of course, want your business to succeed. And in order for you to do that, one important thing that you need to do is to secure yourself a reliable and trusted solar manufacturer. This is because solar manufacturers are the ones that make finished solar products, such as panels, batteries and many more, from scratch for you. In other words, you can say that solar manufacturers are the ones that will help you keep your business afloat. That is why choosing a solar manufacturer is incredibly important — it is also going to be your biggest investment yet — and you should make sure that you do it right.

Solar manufacturers can be found all over the world, with a lot of them found in southeast Asia. However, there are solar manufacturers that can be found in the United States as well. So, if you live in this country, there’s no need to worry about where to find a reliable manufacturer.

SolarTech Universal


SolarTech Universal is an American solar panel manufacturing company that is based in Riviera Beach, Florida. This company is known for making use of SmartWire Technology (SWT) in the solar cells instead of the usual busbars, and this technology reduces the shading on the cell, thus allowing greater light penetration. Aside from that, SWT also creates a dense contact grid of 2,660 points, which minimizes the opportunity for electron/hole recombination. The increased number of contact points allows for increased electron collection as well, thus allowing the cells to produce much greater power output. 

In addition to SWT, SolarTech Universal also makes use of high-efficiency monocrystalline passive emitter rear contact (PERC) solar cells. These particular cells generate more open circuit voltage and current by increasing internal reflectivity. As a result, the cells will be able to achieve an average efficiency of 20.9%.

Long story short, SolarTech Universal produces solar panels that are totally unmatched when it comes to quality. 

SunSpark Technology


SunSpark Technology is technically new to the solar panel manufacturing business, but it’s definitely not new to the solar industry. Its parent company, Yiheng Science and Technology Co.
