Abstract
Abstract Presently available solar cell mounting techniques and substrates are not optimized for use with large area solar panels. The packaging and deployment of single crystal silicon solar cells have imposed a severe constraint on the design of photovoltaic power supplies having capacities in excess of 1500 w. The large area solar cell array (LASCA) is a new concept designed to fill the need for a compact, lightweight space power source capable of providing more than 1500 w of power. It can be launched and deployed in a simple manner and is designed to operate on oriented vehicles in artificial gravity or zero-gravity environments. The system is presented and the major components discussed. The force required to extend the solar panels is calculated, and the force available from extensible boom actuators is given. The LASCA performance as a function of solar panel length-to-width ratio and the amount of acceleration experienced by the array is shown. The power-to-weight ratio as a function of power level at a G of 0.2g is derived.
