Photovoltaics: Solar Electricity from Photovoltaic Conversion. A Nebraska Energy Resource Status Report

摘要

A brief review is given of how solar photovoltaics work, then the electrical power use in Nebraska is summarized. Photovoltaic opportunities and target market areas are identified and the market future is briefly discussed. Market areas include residential, farmstead, parks, communication, and irrigation. Photovoltaic economics are briefly examined. Data are quoted on: typical power required by various electric motors, average yearly solar energy for various US locations, cost of utility generated electricity required to operate electric motors, cost per watt, efficiency, and cost per sq ft for currently available single crystal silicon cell and a thin film cell, estimated area required for a 5% and 10% efficient system, major cost elements of a photovoltaic system, cost of various systems, and cost of a two-day battery storage capability. The federal programs in the photovoltaic area are outlined and some industry activities are presented. (ERA citation 07:049612)
