The top five corporate solar users in America, according to the research that tracks and analyzes commercial solar adoption, are Meta, Amazon, Apple, Walmart, and Microsoft.
Meta currently has the largest corporate solar portfolio in the US after a sharp growth in installed solar capacity from 177 megawatts in early 2019 to 3.6 GW today. Target continues to be the leading corporate user of solar energy on-site, but Microsoft has jumped into the top 10 thanks to the addition of 479 MW of new capacity since 2019.
“Solar energy is a key part of Walmart’s commitment to becoming a regenerative company, powered by 100% renewable energy by 2035,” said Vishal Kapadia, senior vice president, of energy transformation at Walmart. “Our onsite and offsite solar projects have helped us deliver strong progress toward our goal, with 46% of our global electricity needs supplied by renewable energy as of 2021.”
The number of American businesses with at least 100 MW of solar capacity installed has increased from 11 in 2019 to 23 in 2019. In this study, the top 25 corporate solar users are ranked, and 18 of them have carbon-neutral or 100% renewable energy targets. Additionally, the study now keeps track of projects that combine commercial solar energy with battery storage, which is especially beneficial for companies that offer key services or that provide essential information or data infrastructure.
