Title: Analysis and design of a 100-kilowatt solar photovoltaic flat-panel power system for a machining and metalworking facility in Columbus, Ohio. Phase I. Photovoltaic flat panel application experiment. Final report, October 1, 1978-February 28, 1979

Technical Report ·
OSTI ID:5754814

A 100-kW-peak flat-panel photovoltaic power system to supply power to a machine-shop load in Columbus, Ohio has been designed and analyzed by a Battelle-led team. The system will provide three-phase, 240-volt ac power to a Machining and Metalworking Facility which has 100 pieces of machinery and employs 50 machinists and other craftsmen. The system will operate in parallel with the utility which will supply backup power. Due to the close match of the array power output to the workday shop load, only a small amount of the power generated is excess to the concurrent shop demand. When there is any excess, it will be fed to alternate loads at the site, rather than into the utility grid. The system performance analysis indicates that the system will supply approximately 115,000 kWh/year of electrical energy after all loses. The system uses high-energy-density flat-panel photovoltaic modules in a roof-mounted installation, and employs a microprocessor-controlled power conditioning unit. The overall system design, analysis of system performance and design alternatives, and detailed plans for installing, operating, and evaluating the system were developed in the project.
