SUNation’s position in PSEG Long Island reflects more than installation volume; it reflects the strength of a regional platform built to serve customers across multiple energy and service needs.
“Our deep familiarity with the Long Island market give us an execution advantage at every stage of the customer lifecycle,” said John Mucci, General Manager of SUNation’s New York Operations. “That helps us install more projects efficiently, maintain a strong customer experience, and create additional opportunities across residential, commercial, and service, all of which support sustainable growth in our core market.”
