Title: Installation package for concentrating solar collector panels

Abstract

Northrup, Inc., has developed and delivered 300 square feet of Concentrating Solar Collector (ML Series) and Attitude Control System, under the direction of the National Aeronautics and Space Administration. The ''ML Series'' Solar Collector Panels comprise a complete package array consisting of collector panels using modified Fresnel Prismatic Lenses for a 10 to 1 concentrating ration, supporting framework, fluid manifolding and tracking drive system, in unassembled components for field erection. The Installation, Operation and Maintenance Manual, Warranty, List of Materials, Sub-Assembly drawings and Final Field Assembly Drawings are included in the package.

  • Information used to evaluate the design of the Northrup concentrating collector is presented. Included are the system performance specifications, the applications manual, and the detailed design drawings of the collector. The Northrup concentrating solar collector is a water/glycol/working fluid type, dipped galvanized steel housing, transparent acrylic Fresnel lens cover, copper absorber tube, fiber glass insulation and weighs 98 pounds. The gross collector area is about 29.4/sup 2/ per collector. A collector assembly includes four collector units within a tracking mount array.

  • ; ; ; ...
    The first quarterly report and preliminary design data for a Fresnel lens concentrating solar collector including attitude controller are presented. Schedules, technical status, all documents required for preliminary design, and other program activities from October 1, 1976, through December 31, 1976, are presented.

  • The information used in evaluating the design of the Sunmat Liquid Flat Plat Plate Solar Collector developed by Calmac Manufacturing Company is presented. Included in this package are the Subsystem Performance Specification, Installation, Operation and Maintenance Manuals, collector sizing guides, and detailed drawings of the single-glazed collector.

  • ;
    The results are summarized of tests on four concentrating solar collectors at output fluid temperatures from 100/sup 0/C to 300/sup 0/C. Collectors tested were manufactured by Scientific-Atlanta, Inc., General Electric, Del Manufacturing and Suntec, Inc.

  • ;
    The results of tests on a series of five concentrating solar collectors from Suntec Systems, Inc.; Hexcel Corporation; General Atomic Company; McDonnell Douglas Astronautics Company; and Solar Kinetics, Inc. are summarized. The Hexcel design performed better than the others primarily because of a highly reflective, precisely shaped mirror that focused almost all the reflected light onto the absorber. McDonnell Douglas, Suntec Systems, and Solar Kinetics designs were down about 10% in efficiency at temperatures near 300/sup 0/C. The General Atomic FMSC performed at a lower level at low temperatures because of large reflected light spillover, but only about 3 tomore » 4% lower than the others near operating temperatures of 300/sup 0/C. Even the best of these collectors can be significantly improved.« less
