Stacked arrays of thin-wall glass tubes and corrugated thin glass sheets were fabricated and demonstrated to be feasible honeycomb constructions for solar collector heat loss control. Likely design values of honeycomb length and diameter were identified within a region limited by temperature difference across the honeycomb, by excessive infrared emittance and conduction, and by deficient solar transmittance. Experimental and analytical performance studies showed that, under comparable conditions, glass honeycomb collectors achieve the highest thermal efficiencies when compared with single glazed (ALCOA) selective black and single and double glazed nonselective black collectors and are the most cost effective when the inlet temperature above ambient air temperature is greater than approximately 30/sup 0/C.
