Stretched Lens Solar Array: The Best Choice for Harsh Orbits

In past years, very few satellites have flown in orbits that require long durations in the Van Allen radiation belts due to the loss of power, hence lifetime, caused by the radiation. Another recurring obstacle to reliable power in space is electrostatic discharge which is most prevalent in GEO. As power levels continue to increase, arcing failures will become more prevalent. An array that can withstand high voltage, high radiation operation while being lightweight and cost efficient is necessary for the future of the space industry. The Stretched Lens Array (SLA) developed by ENTECH, Inc. is a viable candidate. This paper will discuss recent advances, past and future testing protocols, flight history, and the ability of the SLA to reliably fly in harsh orbits.
