A lot is being said about the future of solar companies with one stalwart, SunEdison Inc. (SUNE), rumored to be going bankrupt. In fact, shares of the company tumbled almost 45% in Friday’s after hours trading. The company has been on a southward trend for some time now. The company’s market value has dropped to a mere $136 million as compared to July last year, when it was valued at almost $10 billion (read: Solar ETFs to Shine in 2016?). Per The Wall Street Journal report, SunEdison is expected to file for bankruptcy in the coming weeks. The report goes on to say that with the company preparing chapter 11 filing and in talks with creditor groups, it is likely that creditors will take control of the company and its power projects. SunEdison is already facing probes by Securities and Exchange Commission and Justice Department. Meanwhile, one of its two yieldcos, TerraForm Global Inc. (GLBL), has warned that the company is at a “substantial risk” of bankruptcy. If the bankruptcy is announced, it could create a ripple effect in the solar industry and the entire alternative energy space. Detractors of the solar industry argue that with expensive solar panels and heavy reliance on government for subsidies, SunEdison could be the first company to fall in a series of dominoes. However, the reason behind SunEdison’s fall is primarily its high debt. It is to be noted that SunEdison has been struggling to finance its projects due to high debt incurred as a result of a string of buyouts, including First Wind and Solar Grid Storage. It turned worse last July when SunEdison entered into a definitive agreement to acquire Vivint Solar in a cash-stock deal worth $2.2 billion. The deal made investors increasingly cautious about its rising debt pressure. These acquisitions, once believed to be strategic, are burning a hole in the company’s pocket. Thanks to these acquisitions, at the end of September 2015, SunEdison’s balance sheet had long-term debt spiraling to $9.8 billion, as per SEC filing. These are company specific issues and don’t show the true picture of the industry at large. In fact, other companies belonging to this industry, like SunPower Corporation (SPWR) and First Solar, Inc. (FSLR), are doing well and did not over-leverage their businesses. Additionally, with SunEdison, a large competitor out of the way, it would easier for these companies to win projects (read: Alternative ETFs to Gain on First Solar Q4 Beat). The solar industry has a well-developed infrastructure, greater efficiencies, and a growing customer base. In fact, boosting solar capacity features high on the Democratic presidential hopeful Hillary Clinton‘s agenda (read: Trump, Clinton Race Ahead: ETFs in Contest). Last year, the U.S. government approved of a five-year extension of the Investment Tax Credit and Production Tax Credit for solar and wind companies (read: Solar ETFs Soar on Tax Credit Extension). With global warming issues gaining momentum and several countries working on renewable sources and efficient alternative energy application, solar companies are here to stay.
