Swift Solar has announced a partnership with solar developer Plenitude for utility-scale pilot testing and evaluation of long-term supply arrangements. Plenitude is a company controlled by Italian energy giant Eni that aims to achieve 15 GW of renewable capacity by 2030. Eni Next, the venture capital arm of Eni, is a strategic investor in Swift Solar.
The partnership represents a milestone in the commercialization of perovskite technology for utility-scale solar energy. The work includes pilot testing of Swift Solar’s technology in a U.S. Plenitude solar facility. This provides early validation of performance and durability under large-scale operating conditions.
“Major developers don’t run pilots unless they see real commercial potential, and this reflects Plenitude’s interest in exploring the next generation of solar,” said Joel Jean, CEO and co-founder of Swift Solar. “We see the same urgency among customers across all industries. Everyone wants better performance and more secure domestic supply chains.”
Swift Solar’s perovskite-silicon tandem technology is expected to achieve module efficiencies of 28% or higher, while conventional solar panels achieve efficiencies of 20% to 24%. This produces up to 40% more power with the same footprint, the company said.
The efficiency benefit will become valuable as demand for electricity from AI data centers increases, Swift Solar said. The technology enables energy generation from limited land areas while reducing installation costs and improving project economics.
Swift Solar’s proprietary perovskite tandem technology is supported by exclusive IP from MIT, Stanford and NREL. The company has more than 40 patents and more than $60 million in funding from venture capital firms, investors and government agencies, including the U.S. Department of Energy and the U.S. Department of Defense.
