The Wyndham Philadelphia-Mount Laurel is an upper upscale 245 room full service franchised hotel by Wyndham Hotels and Resorts and is owned and operated by ARS Hospitality, LLC. The property was selected to undergo a full scale renovation including installation of a 756 KW solar photovoltaic system.


Energy efficiency measures included a kitchen lighting retrofit and installation of HVAC occupancy sensors throughout the property. The lighting retrofit included the removal of all florescent tubes and replacement with LED counterparts. The HVAC sensors were funded in part by the New Jersey Clean Energy Program. Energy conservation measures implemented have resulted in an annual energy savings of 27% and cost savings of $34,000 or 9%.


The solar project includes a panel-mounted system placed on top of 10 carports in the hotel’s parking area, covering 70% of the 400 vehicle parking spaces. The array installation, which cost $23 million, was constructed at no expense to the property since the hotel entered into a Power Purchase Agreement with U.S. Solargy, Inc. It is estimated that this system could produce 50% of the hotel’s electrical needs, approximately 900,000 kWh.

Other Benefits

The Wyndham Philadelphia -Mount Laurel overcame a number of barriers while implementing their solar panel project. One of the main barriers was maintaining guest access to the parking lot while contractors were working on the solar panels during peak hours. Contractors had to ensure a safe environment for guests while still working at an efficient rate. In addition, the research phase of the solar installation took twice as long as planned, and as a result, the project was delayed.
