Solar power tower technology has evolved over many years, is well understood, and is currently being deployed commercially.To address the increasing demand for this technology, eSolar has strategically deviated from the traditional solar plant concept that has historically: 1) utilized mid-to large-sized heliostats arranged in a single field configuration and 2) utilized a single solar receiver.The eSolar plant concept is unique in that it utilizes small (~ 1.1 m2) heliostats, and the solar portion of the power plant configuration is modular and scalable (i.e., multiple receivers).Benefits of small heliostats include: 1) low wind profile that facilitates less complex designs;2) quick, simple field installation performed by local, unskilled labor;and 3) the ability to leverage high-volume production into lower equipment cost.The "modular and scalable" philosophy enables a broader addressable commercial market by offering a generally "standard" product that is flexible relative to plant capacity and configuration without having to redesign solar plant equipment.In addition to strategic benefits, challenges with this approach include: 1) the need for heliostat control solutions that can manage hundreds of thousands of heliostats;2) multi-receiver startup and control, and 3) field piping costs and thermal losses.This paper describes the strategic trade space considerations, supporting analyses, and design decisions that serve as the bases for eSolars unique approach.
