Top 10 Companies in Solar Energy in the US

The United States of America is indeed the largest economy in the world. With an estimated worth of over 17 trillion USD, it would be a huge mistake to consider it small when it comes to the scope of technology adoption. In fact, the country leads the world in so many areas that one dictionary defines the word “American” as “a person who likes to spend money”. This can be attributed to the massive influx of cash that the country experienced during and after the Great Recession of 2008. 

Nowadays, the United States faces a new challenge. As the climate changes and more people become sensitive to the environmental impact caused by human activity, they are looking for alternative sources of energy. Fortunately, they found it in the solar industry, as solar energy technology is improving day by day and becoming more affordable. In today’s article, we’re going to identify ten companies that stand out among the rest and deserve the top spot as companies in the solar energy industry in the United States.
