This Veterans Day, we extend our gratitude to all who have served. Your dedication and leadership continue to inspire progress—both in our communities and across the clean energy industry.
Across the solar industry, new opportunities are helping veterans build on their skills and continue making an impact. Programs like the Solar Ready Vets Network, a U.S. Department of Energy initiative, help veterans and military spouses transition their experience into careers that strengthen our clean energy future. Learn more: energy.gov/eere/solar/solar-ready-vets-network
We’re also looking back at one of last year’s APsystems Project of the Year winners — Carlson Electric’s installation at the Richard I. Bong Veterans Historical Center in Wisconsin.  A project built to honor those who served, and a lasting reminder of how solar innovation can power both progress and purpose. https://usa.apsystems.com/carlson-electrics-richard-i-bong-veterans-historical-center/

A new chapter in solar innovation begins at the Nanjing International Expo Center in China!
This landmark 25MW solar project spans more than 150,000 square meters and features 6,442 APsystems QT2D microinverters powering over 40,000 high-efficiency photovoltaic modules.
The system is expected to generate approximately 24.8 million kWh annually, reducing carbon dioxide emissions by about 25,000 tons each year—the equivalent of planting 900,000 trees.
Setting a new global benchmark for clean energy, this project showcases the power of microinverter technology in driving sustainable, low-carbon development worldwide.
