The Top Solar Companies Transforming Renewable Energy In the United States

Fossil fuels have been the primary source of energy in the United States for over a century. However, as concerns about climate change mount, that pattern is changing.

Fortunately, solar power is the most plentiful energy source on earth. Solar panels harness the energy of the sun through a process known as photovoltaics. The sun is like a nuclear power station, constantly sending energy to the Earth.

The U.S. has conducted extensive research on solar energy; the world’s oldest solar plant is in California. As the focus shifts to renewable energy sources, more states are dedicating resources to prioritize solar energy. For example, Hawaii has declared that it will use 100% renewable electricity by 2045.

Top Solar-energy Companies In The United States

The following companies have made significant progress in the solar energy and renewable energy industries. They are definitely on the upswing and will continue to grow in the future.

NextEra Energy

In October 2020, the biggest news in the solar energy industry was that NextEra had overtaken Exxon as America’s largest energy company by market capitalization. NextEra was worth $900 million more on the stock market at the time than Exxon.

This dramatic increase is a testament to the strength of the solar and renewables sector as a whole, as well as a positive omen for the green economy.

NextEra takes pride in providing clean energy services throughout most of North America, as well as sustainable solutions to evolving energy needs and requirements. In addition to solar, the company also provides wind, nuclear, and natural gas power.


Avangrid is continuing to lead the way in utility-scale solar and will continue to do so as the demand for this type of energy generation continues to grow. With their vertically integrated approach, they produce renewable energy products that are dependable and cost-effective for every customer.

If you’re not familiar with Avangrid, you’ve likely heard of it under its previous corporate name, Iberdrola Renewables. Avangrid may be based in Portland, OR, but its parent company Iberredrola is still based in the Spanish city of Bilbao.

They are a global leader in the renewable energy industry and have the largest portfolio of renewable assets of any company globally. In the U.S., they specialize in wind, heat, biomass, and solar generation.

First Solar

Drawing on its industry expertise, First Solar promises to mitigate risk while providing more consistent, reliable, and affordable solutions for its clients. They focus on R&D and scaling up solar technology to deliver higher energy yield and stable grid integration.

First Solar is currently undergoing a business turnaround. At the start of 2021, First Solar declared that it would transfer 10 gigawatts of under-construction projects to the Leeward renewable energy company.


SunPower skyrocketed to the top of the commercial solar rankings in 2017, and it hasn’t looked back since. They are a pioneer in business solar power and pride themselves on their sustainability and accountability track record in the solar industry.

But solar isn’t their only focus. They’re also a multi-faceted provider of residential, commercial, and solar storage services.

Cypress Creek Renewables

One project at a time, Cypress Creek Renewables is dedicated to creating a sustainable future. They are well-known for the development, financing, operation, and ownership of utility-scale power plants and distributed power facilities throughout the U.S.

With over 8 Gigawatt of solar under development and over 2.5 GW of solar under management, the company is one of the leading providers of solar energy in the United States. Cypress Creek wanted to be at the forefront of the industry from the get-go and contributed to policy and regulatory shaping from the ground up.

Recurrent Energy

Recurrent is a leading provider of utility-scale solar energy and energy storage solutions. Our mission is to build a robust, clean energy infrastructure for large energy purchasers across the United States.

They are based in the USA, but they are a part of Canadian Solar, which is one of the biggest solar power companies worldwide. Recurrent Energy continued to make headlines throughout 2020, announcing new partnerships, additional solar projects, and the successful completion of previously completed projects.


The company’s name rings a bell when you see it on the homepage of their website, which reads, “In 8 minutes, solar energy reaches the Earth, and we harness it.” This is a very good quote because it speaks to the essence of who we are as a company and why we are so successful.

Their real mission is to harness the power of the sun and make it the most cost-effective and dependable form of energy on Earth.

EcoPlexus, Inc.

Developing, designing, engineering, constructing, financing, operating, and owning solar are just a few of the professional services offered by EcoPlexus. They also collaborate with commercial, governmental, and utility markets.

This comprehensive, integrated approach is one of the reasons for their success. In addition to its headquarters in San Francisco, California, EcoPlexus also has offices in Dallas, Texas, and Raleigh, North Carolina. They also have branches in Mexico, Japan, Korea, Taiwan and Vietnam.

Leeward Renewable Energy

It would be a shame to leave out Leeward renewable energy at this stage. This company has made significant progress in renewable energy and with the recent acquisition of a significant portion of First Solar’s business, will be a major player in the market.

In the past Leeward focused on wind farms with a wind farm portfolio of 21 across 9 states. Investments and a growth mindset have led them to diversify into solar and other forms of renewable energy. They are well on their way.

Sustainable Power Group

sPower focuses on the development, construction, and operation of solar and wind energy systems. Unlike some of its competitors, sPower is a self-sustaining generator of electricity and operates over 150 renewable generation facilities throughout the U.S.

While others construct and manage power plants, they maintain ownership and control over the projects they construct. While sPower is based in Utah, it is a joint venture between The AES Corporation (based in Virginia) and Alberta Investment Management Corporation (based in Canada).
