Constance, Germany, 26.05.2025 – Since March 2025, ISC Konstanz has been consulting with
Suniva, the oldest and largest crystalline solar cell manufacturer in the United States and North
America, to accelerate the company’s ramp-up of the first new solar cell production facility in the
United States since 2015.
A team of experienced specialists from ISC Konstanz has assisted Suniva in the optimization process
of its new 1GW PERC production lines at its existing Norcross, Georgia, campus. PERC is particularly
suitable for the U.S. market as it relies on proven, highly efficient technology to maximize production
output, which is critical in supporting the United States’ resurgent module manufacturing sector and
the overwhelming demand for domestic content in the country’s home markets.
ISC Konstanz has led production formula optimization adapting process recipes to local conditions,
and ultimately achieving rapid growth in product efficiency levels and production throughput—key
factors for economic viability.
Suniva has found the relationship to be highly productive in scaling this critical domestic capacity.
“The evolving U.S. regulatory landscape places extreme importance on the need for domestically-
produced solar cells,” says Suniva President Matt Card, “Our partnership with ISC Konstanz provides
Suniva with an exceptional pool of expertise that is allowing us to respond rapidly to the market
need”.
This project is especially meaningful for ISC Konstanz, as a high percentage of production equipment
comes from German manufacturers. “We take pride in saying: A clean energy transition, made in
Germany/Baden-Württemberg!” says Lejo Joseph, head of ISC team.
About Suniva
Suniva is America’s oldest and largest monocrystalline solar cell manufacturer in North America.
Suniva was founded in 2007, out of one of the world’s foremost photovoltaic research institutes, The
University Center for Excellence in Photovoltaics at Georgia Tech, and from research sponsored by
the U.S. Department of Energy. Suniva has established itself as an innovation leader, having
originated and licensed over 150 patents around solar cell development over our 16-year life.
Suniva’s innovative, proprietary cell processing techniques and business model are used to achieve
industry-leading efficiencies while maintaining among the lowest costs in the United States. Suniva
looks beyond its products to work with solar module assemblers, EPC firms and solar plant
developers to enable high-value solar projects benefiting from domestically-made, high-quality and
high-efficiency solar cells.
