Solar4America solar panels review 2024: From under California sky

It is always a pleasure to meet a local manufacturer in the solar market long conquered by Asian companies. Can our countrymen compete with Chinese manufacturers? Let’s find out – here comes our Solar4America solar panels review.  

Solar4America makes solar panels in Sacramento

Solar4America is a California-based solar panel manufacturer with a 140,000-square-foot production facility in Sacramento. The company has grown to become one of the largest domestic solar module manufacturers in the US, producing over 1.3GW of solar panels annually. Solar4America’s commitment to American manufacturing ensures that their solar panels are crafted with the highest standards of quality and reliability.

Solar4America is one of the few solar companies in the US that not only manufactures but also installs solar panels. Company’s product line features both residential and more powerful modules suitable for both home and business applications. But that’s not all – Solar4America also offers smaller solar panels for RVs or boats, as well as thin-film solar panels for outdoor activities. Besides solar panels, they also manufacture batteries, inverters, charge controllers, and generators.

40W to 550W

power output range

Solar4America offers an impressive power range. You can find both tiny little 40W portable folding panels and impressive 550W bifacial modules in their product line. The company can cater to all: campers, homeowners, and businesses.

19% to 21%


The efficiency ratings float from a bit below 19% to over 21%, which is considered average on the market. The better the power output and efficiency are, the fewer panels and less space you need to build a powerful system, which is especially important when space is a constraint.

25 years

product and performance warranty

Solar4America also provides a comprehensive warranty package. The company’s product warranty covers product defects for 25 years, which is nice because not many companies provide such long warranties for their products. The company’s performance warranty guarantees that panels retain over 85% of their rated output after 25 years.

$0.6 to $1

 price per watt

American-made PV module prices tend to be about 20% higher than that of Chinese solar panels. Yet Solar4America’s solar panels cost per watt ranges from $0.6 to $1, which is not that high even compared to Asian brands.

Solar4America solar panels: Cons
