SunEdison, based in the United States, was a leading renewable energy company that specialized in solar energy and energy storage solutions. It was established in 1959 as a holding company called MEMC Electronic Materials. The company entered the solar market in 2006 and went public in 2008.

In 2016, SunEdison filed for bankruptcy and sold off its assets. SunEdison's headquarters were located in Maryland Heights, Missouri, United States. The company had a global presence, with operations in North America, Europe, Asia, and Africa.

It aimed to develop, build, and operate solar power plants, as well as provide solar panels and energy storage solutions. SunEdison offered a wide range of products and services, including solar panels, energy storage systems, project development, financing, and operation and maintenance services for solar power plants. The company worked with utility-scale, commercial, and residential customers to provide clean and renewable energy solutions.

The company had several noteworthy subsidiaries and joint ventures. These included Renova Energia, a Brazilian renewable energy developer, TerraForm Power and TerraForm Global, yieldcos that owned and operated renewable energy assets, and Greenlight Planet, which focused on providing solar products to underserved communities in developing countries. SunEdison faced tough competition in the renewable energy market.

Although it was once considered a dominant player, financial difficulties and strategic missteps led to a decline in its market position. The company struggled with a high debt load and faced legal challenges, ultimately resulting in bankruptcy. As of now, SunEdison is no longer an active company and its brand and assets have been mostly liquidated.

Its downfall serves as a cautionary tale in the renewable energy sector. It highlights the importance of financial stability, sound strategy, and effective execution in this rapidly evolving industry
