An American solar photovoltaic manufacturer, Solestial, has announced its plans to supply radiation-resistant, ultra-thin silicon heterojunction photovoltaic components to the Bulgarian satellite manufacturer Endurosat by 2025. While the companies have not disclosed the initial order size, they stated in a joint announcement that the agreement includes an additional 7 kilowatt capacity to meet future power demands.
The Solestial components will serve as the primary power source for Endurosat’s Frame small satellite series, which is an evolved auxiliary payload adapter (ESPA) class satellite, scheduled for its maiden flight in the first half of 2026. The manufacturing processes employed by both companies are designed to shorten delivery times.
Endurosat is set to produce 2026 ESPA-class satellites monthly starting from the second quarter of 2026. These satellites are being developed for various mission types, including Earth observation, communication, and defense applications. Endurosat has international operations in Denver, Toulouse, and Berlin, and recently raised €43 million in venture capital to fund its production expansion.
Meanwhile, Solestial secured $17 million in venture capital to establish a dedicated solar cell and component manufacturing facility in Tempe, Arizona. Since 2023, the company has been automating and expanding its plant to reduce costs and accelerate delivery times.
