Technical Specifications
Flexible
Our unique packaging replaces cover glass and bulky substrates with polymer and ceramic films to produce a thin and flexible solar power module. Solestial SPMs can be safely rolled into a 5 cm bend radius.
Low mass
Our total solar power module mass is 420 g/m2. This includes the cells, interconnects, and protective film layers.
Bifaciality
Bifacial technology allows a photovoltaic module to generate power from light received on either side of the module. Our silicon heterojunction solar cells are intrinsically bifacial, allowing us to rethink packaging for our solar power modules to maximize power. Bifacial technology has the potential to change the way we think about solar arrays and spacecraft orientation. This technology is available to our customers on demand.
Long-lasting cell-to-cell interconnects
Our proprietary cell-to-cell interconnection technology is optimized for very thin crystalline silicon solar cells that can withstand up to 10 years in a variety of destinations in space.
UV and AO protective coatings
The AO and UV protective coatings leveraged by Solestial have been used in the space solar power industry for many years and are proven to protect modules from the damage encountered in low Earth orbits.
Scalable automated manufacturing
Solestial solar power modules are designed for manufacturing using processes derived from the terrestrial solar and PCB industries that can scale to gigawatts as the space industry grows. Solestial’s technology allows us to manufacture large-scale modules in weeks, not months or years.
