U.S. businesses have installed a total of nearly 19 GW of on-site and off-site solar through the first nine months of 2022, about double the amount installed through 2019, according to a report released Tuesday by the Solar Energy Industries Association.

Meta tops the 2022 list of U.S. corporate solar users — growing from 177 MW in early 2019 to 3.6 GW today —  followed by Amazon, Apple and Walmart. Microsoft, which ranks fifth, has “leapt into the top 10” by adding 479 MW of capacity since 2019, SEIA states in a release provided with the report. Target ranks sixth, but SEIA reports that it “remains the top onsite corporate solar user.” 

Half of all U.S. corporate solar capacity has been built in “the last two and half years,” SEIA estimates, and U.S. companies are now responsible for 14% of installed solar capacity in the country. 

“Total commercial solar installations are expected to double again over the next 3 years with nearly 27 GW of off-site corporate solar projects scheduled to come online by 2025,” SEIA’s release states. “This represents nearly a third of the total contracted solar pipeline” in the U.S.

Meanwhile, more than 75 multinational corporations have committed “to collaborate with 14 countries — potentially paving the way for over $100 billion in clean energy infrastructure investment” as part of the Clean Energy Demand Initiative, the U.S. State Department said Nov. 10.

The State Department and the Clean Energy Buyers Alliance announced the formation of a secretariat for the initiative during COP27.

The secretariat will strengthen CEDI efforts by “fostering public-private collaboration, maximizing potential for investment, and streamlining the investment process,” the State Department said.

Companies involved in the initiative include U.S.-based giants such as Amazon, HP and Nike.
