Simulation, design and testing of a building-integrated hybrid concentrator photovoltaic system

Abstract

During the course of the project, a computer model was created to analyze the performance of the system; an experimental test rig was constructed to analyze these simulated results; and four different actuating mechanisms were developed and studied to varying degrees. Our results showed that the system, at its current stage of development, does not meet the 5-year target. However, several steps are proposed by which the system should be able to approach this target and open up a wider market to photovoltaic devices.

The modeling, testing, and analysis of a next-generation building-integrated photovoltaic system is presented. The purpose of the system is to overcome obstacles to wider implementation in the solar power market by creating a system that utilizes the solar energy in as many ways as possible. The system consists of an array of solar modules positioned between the two transparent walls of a double-skin building façade. In addition to electricity production, the system captures thermal energy, reduces building heat gain, provides natural daylighting to the interior of the structure, and replaces current building materials in a fully integrated system. The overall goal of the project is to create a design which can return its investment in the form of energy production and cost savings in a period of 5 years or less in major US markets.
