Pumpkin Solar Panel headed for the Moon

Pumpkin recently delivered a 72W solar panel that is destined for the Moon. Configured as a single 6x10S1P + 1x12S1P solar array on a carbon fiber and aluminum honeycomb substrate, this panel will drive a Pumpkin power system consisting of a Pumpkin EPSM1 multi-channel high-efficiency power system with two Pumpkin BM2 100Wh batteries attached, all in a lunar rover.

This solar panel has the usual hallmarks of a Pumpkin PMDSAS solar array, including redundant paths for every solar cell string's signal net, redundant bleed resistors, multiple temperature sensors, an extremely high degree of design symmetry to reduce cost, and many design details customized for this particular application. The signal traces are implemented exclusively on the top layer of the PMDSAS sub-panels via careful maze routing, for the ultimate in reliability.
