Technical Evaluation of Four Amorphous Silicon Systems at NREL

Research output: Contribution to conferencePaper


The National Renewable Energy Laboratory (NREL) has been studying the performance of small grid-tied systems since 1992. These 1 to 2 kW systems are designed to ac conduct in-situ technical evaluations of the PV arrays in a high voltage configuration. This paper will concentrate on the; performance and reliability of four amorphous silicon systems currently being tested in Golden, Colorado. Thefour systems include arrays from United Solar Systems Corp., Solarex, and Advanced Photovoltaic Systems. Each of these systems is tied to the grid with an Omnion inverter. The data show that most systems employing amorphous silicon exhibit; stable performance over time and are viable for commercial scale up to larger systems.
