Walmart is investing in 74 different rooftop solar projects in Maryland and Illinois in partnership with Solar Landscape. The bulk of the commercial rooftop solar projects are expected to be up-and-running by the end of 2025 and estimated to produce enough electricity to power more than 3,600 homes.
“Walmart’s decision to install solar on many of its Illinois and Maryland locations helps underscore that the flat sunny roofs of big box stores are perfect places to put solar panels,” said Johanna Neumann, Senior Director of the Campaign for 100% Renewable Energy at Environment America Research & Policy Center. “I hope this experience gives Walmart the confidence to bring the benefits of solar to all its locations.”
In 2024, Walmart outlined plans to support 10 GW worth of clean projects – including 2 GW of community solar. It’s estimated that nearly half of American households can’t install their own solar system. Community solar, which allows community members to purchase a portion of electricity from a solar farm, helps those who can’t get solar panels themselves still find a way to reap the benefits of clean energy.
Walmart has more rooftop solar potential than any other retailer in America according to the report Solar on Superstores.
