Largest solar rooftop system in the US installed on the Mandalay Bay Convention Center

Mandalay Bay Las Vegas


As solar PV starts hitting the mainstream across the United States, one of the Las Vegas’ most famous buildings has adopted the country’s biggest rooftop array. The project was a joint partnership by NRG Energy and MGM Resorts International, and utilized some top-of-the-range technology from Ten K Solar.

The colossal rooftop system has been installed on the roof of the Mandalay Bay Convention Center, with over 26,000 modules making up a combined capacity of 8.3 MW. The project has been completed in two sections, with the most recent utilizing Ten K Solar’s REFLECT system, which is fully integrated, including a racking system with no roof penetration.

NRG is the owner of the array, and will sell the electricity to MGM Resorts International on a 25-year power purchase agreement. The system has the capacity to power 25% of the entire electricity demand of the Mandalay Bay Resort and Casino complex.

“Companies like MGM Resorts are driving an evolution in America’s energy mix as they seek cleaner sources of power that provide more certainty over energy costs,” ,” said Craig Cornelius, Senior Vice President of NRG Energy. “The solar array atop Mandalay Bay is stunning in its scope and functionality, and we’re thrilled to have MGM as a partner.”
