Use of an Iterative Research and Development – System Engineering Approach for the Caltech Space Solar Power Project

We describe the application of an iterative research and development/system engineering process being utilized in the Caltech Space Solar Power Project (SSPP). We begin with a brief description of the SSPP approach to achieving a viable space solar power capability. This approach centers on eliminating mass from the satellite through the use of ultra-light weight materials, advance photovoltaic devices and modern CMOS integrated circuits. These three technology areas are the focus of our research activities. We then describe the system model that uses the projected performance of the various technologies to estimate the levelized cost of electricity (LCOE). Researchers can use the model as a "what if" tool to assess the impact of a technology on space solar power. We then show some examples of trades and insights the model provides and conclude with some observations.
