Building the Future of Energy

1366 Technologies provides customers with high-performance silicon wafers that both leverage their existing billion-dollar cell and module investments and enable a long-term, differentiated product roadmap. We believe that our technology has immense potential to change the world’s ability to access solar, and our vision for the future is one where solar energy displaces coal as the cheapest fuel source on the planet. We are convinced that this will happen before the end of the decade. 1366 Technologies will play an important role in getting us there.

Direct Wafer Systems on Three Continents

A 192 module array on the GE campus in Schenectady, New York, features panels made with 1366's Direct Wafer® products.

The appeal of the Direct Wafer® process extends downstream, where customers seek advanced, high-quality systems with lower technology costs. Our highly efficient manufacturing process enables 30% faster energy payback for the modules and uses safe, earth abundant raw materials appropriate for addressing the world’s energy needs at a terawatt scale.

The Story Behind Our Name

The “1366” in 1366 Technologies refers to the solar constant or the amount of the sun’s energy that hits the earth’s atmosphere per square meter. It’s an impressive number and a constant reminder that the sun over our heads reliably provides all of the energy our planet currently needs.
