Solar Junction Corporation Key Developments

Solar Junction Corporation and Sierra Nevada Corporation Launch Disruptive Space Solar Array Technology

Sierra Nevada Corporation (SNC) and Solar Junction Corporation (Solar Junction) are launching a revolutionary new technology that will increase the efficiency of spacecraft solar array production and operation and lower the overall cost, providing a direct savings to customers. These advanced solar arrays are manufactured utilizing a patent-pending Surface Mount Technology (SMT) assembly method. This method allows each cell to be installed faster, closer together and more accurately than ever before. This advancement significantly increases the amount of power generated per area, while decreasing cost and delivery time. SNC has teamed with Solar Junction, an innovative semiconductor technology company based in San Jose, California, to develop this industry-first spacecraft solar array technology. Solar Junction’s high-efficiency, multi-junction Surface Mount Cell with Coverglass (SMCC) enables automated, high-speed pick-and-place assembly of SNC-designed and manufactured solar arrays. SNC’s low-cost SMT solar array powered by Solar Junction’s SMCC cells. Efficiency and Reliability: The SMT approach allows SNC and Solar Junction to design, fabricate, inspect and test a complete solar array within a drastically reduced timeline. This technology produces a number of benefits that address overall system design and performance, resulting in significant savings at the spacecraft level. In addition to the improved design, SNC has implemented a zero-touch labor process which vastly reduces room for human error and allows each interface to undergo a more rapid and precise quality test. Once on-orbit, the small cell size and increased number of strings per panel in the design makes the array more resilient to solar interference factors such as partial shadowing from the spacecraft body and debris. Power System Heritage: SNC has recently completed its first contract to integrate this advanced technology onto its solar arrays under the Air Force Research Laboratory’s (AFRL) Satellite for High Accuracy Radar Calibration program. The 5U cubesat array was delivered within a few months after contract award and will result in a significant power output increase. This first-use of SNC’s and Solar Junction’s Surface Mount Technology will prove the efficiencies and benefits of this highly-scalable system. SNC has developed and delivered several solar array systems, including 18 arrays for the ORBCOMM Generation 2 constellation currently on-orbit. Eight deployable arrays were recently delivered to Southwest Research Institute for integration onto NASA’s CYGNSS spacecraft, and two articulated arrays are being finalized for the AFRL’s STPSat-5, which SNC is the prime contractor for.
