Title: Low-cost, high-performance solar flat-plate collectors for applications in northern latitudes

Abstract

Solar flat plate collector designs have been developed which incorporate high performance polymer film and laminate technology that have a projected manufacturing cost approaching $15/m/sup 2/ and potential thermal performance consistent with the best commercial solar flat plate collectors available today.

  • Polymeric films are used in the construction of the absorber and window portions of a flat plate solar collector. The absorber heat exchanger consists of a channeled liquid envelope constructed using a polymeric film and metal foil laminate. In addition, the composite films and light frame monocoque construction contribute to very light weight and low cost. The use of high-performance polymers permits low-loss designs with high thermal performance. The construction concepts are consistent with high speed mass production and installation with manufacturing cost projections of $15/m/sup 2/. Tests performed at Brookhaven National Laboratory (BNL) and elsewhere indicate performance potential consistentmore » with applications incorporating solar absorption air conditioning.« less
  • Separate abstracts were prepared for 21 papers in this workshop proceedings. Topics covered include: polysilicon material requirements; economics; process developments in the USA and internationally; and the polysilicon market and forecasts. (LEW)
  • Measurements in Solar House I at Colorado State University have provided comparison data on space heating, water heating, and cooling by systems in which flat-plate collectors and evacuated tube collectors were used. Data were procured on 47 days during operation of the flat-plate collector and on 112 days when the house was heated or cooled by the evacuated tube collector system. It was concluded that the system comprising an evacuated tubular collector, lithium bromide absorption water chiller, and associated equipment is highly effective in providing solar heating and cooling to a small building, that it can supply up to twicemore » the space heating and several times the cooling obtainable from an equal occupied area of good quality flat-plate collectors, and that a greater fraction of the domestic hot water can be obtained by supplying its heat from main storage. The cost-effectiveness of the system, in comparison with one employing a good flat-plate collector, can be determined when commercial pricing data are made available.« less

The cost-effectiveness of the system, in comparison with one employing a good flat-plate collector, can be determined when commercial pricing data are made available. A summary of monthly and annual energy use for space heating, domestic hot water (DHW) heating, and space cooling is presented. The collector performance is presented. The first two months of data were obtained with the system employing flat-plate collectors, whereas heating and cooling during the following nine months were supplied by the evacuated tube collector system.« less
  • A residential solar domestic hot water system utilizing tubular solar collectors is analyzed for climatic conditions typical of various regions of the Northeast. Experimentally determined system parameters are used in analytical simulations to compare the performance of systems using two different flat plate collectors to the system using the tubular type. A cost/benefit analysis is performed to determine the economic feasibility of the various systems.
