Abstract: We consider the feasibility of low-concentration CPC’s for low-temperature applications. A quantitative assessment of optical gains versus thermal losses, and of savings in reflector area, leads ...

Abstract: Low-concentration, stationary, nonimaging concentrators (CPC’s) with flat receivers illuminated on both sides are considered as viable alternatives to flat-plate solar collectors. Closed-form, analytic ...

Abstract: An approximate analysis of multi-pass, closed-loop solar systems with well-mixed storage tanks is presented. The thermal coupling of the storage tank both to the collector-storage loop (“charging” ...

Abstract: For single-pass open-loop solar thermal energy systems, in which the flow rate can vary with radiation but is constrained to have a given annual average, an upper bound is derived for the ...

Abstract: The two-stage linear Fresnel reflector solar concentrator is analyzed via an in-depth study of an installed, nominally 220 KWt system. The concentrator includes: (1) a primary linear Fresnel ...

Abstract: We present an analytic method for predicting the long-term performance of solar energy systems with more than one collector brand (“multi-stage” systems). This procedure enables the designer to ...

Abstract: We propose a new method for manufacturing and deploying amorphous silicon solar cells which is based on creating an effectively “bifacial” photovoltaic device by utilizing part of the glazing ...

Abstract: Stationary, nonevacuated CPC solar collectors are a promising alternative to corresponding flat plate collectors in that they offer superior yearly energy delivery at comparable cost for low-temperature ...

Abstract: The design, analysis, construction and testing of a novel solar collector is reported. The Reverse Flat Plate Collector (RFPC) is intended to be a stationary, nonevacuated, low-technology, medium ...
