These are the most proven, cheap, and powerful space-grade silicon solar cells in the market, with titanium oxide and aluminum cover glass and cell interconnects (3) installed, they have been flown many times in many CubeSat missions.

They are very tough, with proven survivability of 10+ years with a reasonable EOL degradation level due to their coating, they have multiple points linked to the substrate, and even a broken-in-half cell keeps working if properly installed. We have 300+ units in inventory.

Proven reliability is a cornerstone of EXA's solar cell technology, crafted from high-purity Silicon material for enduring performance with a lifespan exceeding 20 years. Backed by flight heritage in space missions, these solar cells have demonstrated exceptional resilience in the most demanding environments. Leveraging an existing supply chain, EXA ensures scalability, maintaining consistency and reliability in every solar cell.

Designed to meet the needs of both terrestrial and space applications, EXA's solar cells are the perfect choice for long-flight-duration spacecrafts. Their custom design options allow for flexibility with customizable shapes, sizes, and a sleek black appearance, ensuring seamless integration and conformability to diverse spacecraft designs.
