As of June 2022, the United States' total installed solar capacity reached 130.9 GWdc — enough electricity to power 23 million homes. That’s a lot of solar panels.

But most of the panels generating that renewable energy weren’t made in America. Until recently, many homes, businesses, and solar developers used solar panels produced overseas. Like many other goods, they were simply the most economical and readily available option. However, with new legislation and supply chain pressures, that’s quickly beginning to change.

Why Install American-Made Solar Panels?

There are a few different benefits to installing solar panels made in the USA:

  • With the Inflation Reduction Act, using domestic products will allow businesses to increase their federal tax credit by 10% if the 40% domestic content criteria is met - see below
  • It supports the US economy, businesses, and workforce
  • Leading international companies are beginning to manufacture in America, increasing the availability 

The new push for domestically manufactured solar panels started after two events.

In 2018, a 30% tariff was levied on imported solar panels. This was extended in 2022 and incentivizes US-based solar panel manufacturing. As a result, a few of the top international solar panel manufacturers began setting up shop in the states, and US-based firms also increased capacity. However, as of June 5th, 2022, the solar tariff has been suspended for 24 months by the Biden Administration.

The next event was the passing of the Inflation Reduction Act (IRA). The IRA is making some big changes in the way the federal tax credit works for solar.

An additional 10% will be added to the tax credit if at least 40% of the solar system equipment is produced domestically. The specifics of how the 40% will be calculated still need to be released, but we would assume it would include solar panels, inverters, and other system components.

List of American Solar Panel Manufacturers

Here is a list of the solar companies that manufacture panels in the United States. Purchasing US-built solar panels from these companies should count towards your 40% domestic content for that extra 10% tax credit in the IRA.

But first, a quick note. These manufacturers are listed in alphabetical order and don’t indicate any preference towards these companies (Check out our top solar panel list). This list features companies headquartered in America as well as international companies with manufacturing facilities in America. It does not include companies headquartered in America with no American-based manufacturing.

Top 3 Best American-Made Solar Panels

While many American solar manufacturers produce great, high-quality, well-performing panels, here are America’s favorites.

We’ve gone through the leading manufacturers, choosing and ranking them based on the following factors:

  • Product Warranties: How long the manufacturer stands behind manufacturing-related issues
  • Performance Warranties: Ensure the panels will maintain a specified efficiency level for the duration of the warranty - the rate at which they will degrade
  • Panel Efficiency: The percentage of electricity the panels can produce vs. the energy they receive
  • Price

Choosing The Best American-Made Solar Panels

When installing a solar energy system, the panels you choose will greatly impact the rest of the system. Be sure to choose a make and model that suits your energy goals and budget.

Choosing American-made panels can help in this respect. With many leading manufacturers producing panels in America, those looking to install solar have a wide variety of options to buy domestically. This makes getting that extra 10% tax credit for commercial installations that much easier!
