NRG Energy and MGM Resort International today announced the completed expansion of the nation’s largest rooftop solar array atop the Mandalay Bay Convention Center in Las Vegas.

The rooftop array includes more than 26,000 photovoltaic (PV) panels which produce a combined 8.3 MW of electricity and can supply up to 25 percent of the power used by the Mandalay Bay Resort and Casino properties. The installation is projected to displace about 8,400 metric tons of carbon dioxide annually.

The project utilizes Ten K Solar’s REFLECTTM and includes 4,644 modules, 180 inverters, and a racking system that requires no roof penetrations. Parallel cell architecture allows modules to capture non-uniform irradiance from reflected light, and 3M Cool Mirror FilmTM reflects only the wavelengths of light that the PV cells can use.

“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 and head of NRG’s Renewables group. “The solar array atop Mandalay Bay is stunning in its scope and functionality, and we’re thrilled to have MGM as a partner.”

NRG owns the installation and will operate it for MGM. The resort will purchase all electricity generated by the solar array via a 25-year power purchase agreement.
