10 Biggest Solar Companies

JKS, CSIQ, and SEDG top the list of the 10 biggest solar companies

Governments, businesses, and individual consumers are increasingly looking toward alternative and sustainable forms of energy beyond fossil-based fuels as signs of climate change escalate. While solar and other alternative energies tend to be more expensive or more difficult to produce upfront compared with fossil fuels, they have the primary benefit of leaving behind a significantly smaller environmental impact. Solar companies are experiencing a period of growth following incentives provided by the Inflation Reduction Act of 2022, which allows taxpayers to subtract 30% of the cost of solar power from their taxes through 2032.

These are the 10 biggest solar companies by 12-month trailing (TTM) revenue. This list is usually limited to publicly traded companies in the U.S. or Canada, either directly or through ADRs. However, many in the solar industry are based and listed outside of those countries, so excluding any companies would not correctly represent the industry.

Some foreign companies may report semiannually and may have longer lag times. All data are courtesy of YCharts and are current as of Dec. 22, 2022.
