20-kW Solar Photovoltaic Flat-Panel Power System for an Uninterruptible Power-System Load in El Paso, Texas. Phase Ii. System Fabrication. Final Report October 1, 1979-May 31, 1981
The system plans, construction, integration and test, and performance evaluation are discussed for the photovoltaic power supply at the Newman Power Station in El Paso, Texas. The system consists of 64 parallel-connected panels, each panel containing nine series-connected photovoltaic modules. The system is connected, through power monitoring equipment, to an existing DC bus that supplies uninterruptible power to a computer that controls the power generating equipment. The site is described and possible environmental hazards are assessed. Site preparation and the installation of the photovoltaic panels, electrical cabling, and instrumentation subsystems are described. System testing includes initial system checkout, module performance test, control system test. A training program for operators and maintenance personnel is briefly described, including visual aids. Performance data collection and analysis are described, and actual data are compared with a computer simulation. System drawings are included. (LEW)
