PROMOTION — The SunSource commercial energy system from Lennox Commercial integrates directly with 3- to 6-ton solar-ready Energence rooftop units, which provides effective efficiency levels of 34 SEER and beyond, according to the company. The system collects energy from the sun and feeds it directly into the rooftop unit. Any excess electricity is sent to the rest of the building for other uses, or back to the power grid, possibly earning a credit on monthly utility bills.
