Maxeon Solar Technologies and Hardt Electric Enable the American College of Chest Physicians to Power HQ with Clean Solar Energy

48,500 square-foot, LEED-certified facility now powered by advanced solar photovoltaic (PV) system

SAN JOSE, Calif., Sept. 30, 2025 /PRNewswire/ -- Maxeon Solar Technologies, Ltd. (NASDAQ:MAXN), a global leader in solar innovation and channels, together with its Preferred Partner, Chicago-based Hardt Electric, have announced a successful new solar energy installation to help power the American College of Chest Physicians (CHEST) headquarters in Glenview, Illinois.

CHEST's solar system is projected to generate approximately 341,000 kWh annually, offsetting nearly 30% of the facility's electricity use. That translates into avoiding about 242 metric tons of CO₂ emissions each year—the equivalent of taking 54 cars off the road, eliminating the burning of 27,000 gallons of gasoline, or planting 4,000 tree seedlings and growing them for a decade. Beyond reducing carbon, this shift lessens harmful pollutants that contribute to asthma and other respiratory conditions, directly supporting CHEST's mission to advance lung health and improve air quality for the Chicagoland community.

"The solar installation at CHEST headquarters reflects our continued commitment to social responsibility and to advancing lung health," said Robert Musacchio, PhD, CEO of the American College of Chest Physicians (CHEST). "By lessening our reliance on conventional energy sources, we are addressing one of the leading contributors to air pollution, which is closely linked to respiratory disease." 

Hardt Electric, serving as the project's EPC (Engineering, Procurement, Construction) contractor, designed and installed a roof-mounted PV system tailored to CHEST's facility and energy goals, consisting of over 560 highly efficient and exceptionally reliable solar panels from renewable energy innovator Maxeon.

"Maxeon solar technology has been developed through over four decades of research and innovation, delivering industry-leading efficiency and durability," said Michael Hynes, Business Development Manager at Maxeon. "Our panels capture more sun in low light conditions—creating more energy earlier in the morning, on cloudy days, and later in the evening. And Maxeon panels maintain their power advantage over time with the industry's lowest degradation rate. This technology allows Maxeon to have an industry-leading, 40-year warranty that important installations like CHEST can depend on to produce clean energy for decades."

For Hardt Electric, the CHEST project represents more than a technical achievement—it reflects shared values. Both organizations are committed to sustainability, health, and building a cleaner future for communities in Chicago and beyond.

"CHEST is a leader in advocating for lung health, and this project demonstrates that their values extend beyond clinical care into environmental stewardship," said Peter Hardt, President of Hardt Electric. "We're proud to deliver an energy solution that supports their mission, supports a healthy environment, and offers an R.O.I that will help this organization focus funding that advances pulmonary health."
