Solar energy comes directly from the sun. The most common way to capture this energy is through solar panels. Photovoltaic solar panels convert sunlight directly into electricity for homes, businesses and communities. Thermal solar panels use the sun’s heat for water and space heating. 
In 2023, solar power made up about 3.9% of all electricity produced in the United States.
In Missouri, solar provided 2.06% of the state’s electricity in 2023. Almost 80% of this came from small-scale systems, such as solar arrays installed on rooftops.
Beginning in January 2025, large utility-scale solar systems began producing more electricity than small-scale systems for the first time. Utility-scale solar now makes more than twice as much electricity as small-scale systems and Missouri utilities are expected to continue growing their solar capacity. A recent example is Ameren Missouri’s new Reform Renewable Energy Center project, which has plans to incorporate energy storage capabilities along with solar generation.
Some reasons for this growth in utility-scale solar is due to higher energy needs, utility sustainability targets and portfolio diversity goals. In addition, solar construction is relatively low-cost and quick compared to other energy infrastructure needs.
Solar panels can help lower energy costs and reduce environmental impacts from energy consumption. If you are interested in installing solar panels, consider the following:
The department can offer general advice regarding solar energy systems, but it cannot recommend particular businesses. Visit the U.S. Department of Energy, BBB St. Louis, Federal Trade Commission and Missouri Solar Energy Industries Association for additional tips when considering solar energy systems.
For consumer protection concerns, contact the Missouri Attorney General, the Federal Trade Commission or the Missouri Solar Energy Industries Association.
