Top Solar Contractors 2021

Energy Service Partners Recognized as Top U.S. Solar Installation Company 

TORRANCE, CA – July 20th, 2021 — The U.S. solar industry is on the upswing, thanks to a pro-renewables presidential administration and increased concern over climate change. Energy Service Partners (ESP) has had a front-row seat to this action, with business increasing more than 40% over the last year. Solar Power World has recognized the company’s installation success by ranking ESP at No. 94 in the United States overall on the 2021 Top Solar Contractors list. ESP placed at No. 15 overall in Residential-specific installers nationwide.

The Top Solar Contractors list is developed each year by Solar Power World to honor the work of solar installers in the United States.

“Not even COVID-19 closures and slowdowns could prevent the solar industry from installing fantastic numbers last year,” said Kelly Pickerel, editor in chief of Solar Power World. “The Solar Power World team is so glad to recognize over 400 companies on the 2021 Top Solar Contractors list that not only survived a pandemic but thrived in spite of it.”

The U.S. solar industry grew 43% in 2020, installing more solar panels on homes, businesses and across the country than any other year on record. The residential market saw an 11% increase, which is remarkable considering the difficulties of maneuvering home solar projects through pandemic precautions.

The federal government passed a two-year extension on the solar investment tax credit (ITC) at the end of 2020, which will further accelerate solar adoption across all market segments. After installing 19.2 GW in 2020, research firm Wood Mackenzie expects the U.S. solar market to quadruple by 2030. 

ESP employs 115 people who installed 22,171 KW (over 22 MW) of solar power in 2020. Since its founding in 2015, the company has installed over 47 MW of solar. The company is actively seeking new sales partners who need help installing new solar contracts, and currently works with hundreds of sales partners and subcontractors.
