Field Testing and Performance of an Amonix Multi-Junction Cell Module at the University of Nevada Las Vegas

This paper discusses the installation, operation, and performance of a high concentration photovoltaic single-plate, multi-junction module developed by Amonix and installed at the Center for Energy Research at the University of Nevada, Las Vegas (UNLV). The paper discusses the objectives and goals of this project and describes the principal of the Fresnel optics, the module, and how it was attached to the Amonix 25-kW unit located at the UNLV Center for Energy Research. Also described are how the module is connected to a load and the measurements taken. Data is presented in the paper showing the module has produced power for over 2200 hours at a power efficiency of 26% to 28.6%. Data is also presented showing the next generation single-plate, multi-junction module achieving an efficiency of nearly 30%.Copyright © 2007 by Midwest Research Institute
