TL;DR: In this article, a parametric study on the thermal performance of a solar air collector with a v-groove absorber has been investigated, and the results show that the v-Groove collector has considerably superior thermal performance to the flat-plate collector.
Abstract: In this paper, a parametric study on the thermal performance of a solar air collector with a v-groove absorber has been investigated. In this single-cover collector, the air flowing in the channel formed by the v-groove absorber and the bottom plate—which is flat and insulated—is along the groove, aiming at enhanced heat transfer rate between the air and the absorber by increasing the heat transfer surface area, which is crucial to the improvement of thermal performance of a solar air collector. To quantify the achievable improvements with the v-groove absorber, a flat-plate solar air collector where both the absorbing plate and the bottom plate are flat, is also considered. The thermal performance of these two types of solar air collectors is analyzed and compared under various configurations and operating conditions. The results show that the v-groove collector has considerably superior thermal performance to the flat-plate collector. It is also found that to achieve better thermal performance, it is essential to; use a small size of the v-groove absorber for the v-groove absorber collector and to maintain a small gap between the absorber and the bottom plate for the flat-plate collector; to use selected coatings that have a very high absorptivity of solar radiation but a very small emissivity of thermal radiation on the absorber and glass cover; to
maintain an air mass flow rate above 0.1kg/m2s; and to operate the collectors with the inlet fluid temperature close to that of the ambient fluid.

27 Apr 1978TL;DR: In this article, the authors propose a system including at least a pair of mounting spars supported in a spaced-apart parallel relationship by modular sections constructed of standardized hardware for mounting one or more solar collector panels in predetermined positions on stationary surfaces.
Abstract: A system including at least a pair of mounting spars supported in a spaced-apart parallel relationship by modular sections constructed of standardized hardware for mounting one or more solar collector panels in predetermined positions on stationary surfaces. The system includes provisions for accommodating expansion and contraction of the collector panels and insulating the manifold pipes employed in a solar installation for preventing radiation heat losses.

Abstract: Due to the dramatic advances in commercial multi-junction solar cells with 40% conversion efficiency, solar concentrator capable of delivering flux levels of hundreds to thousands of suns at high collective efficiency is the key factor for the success of novel Concentrator Photovoltaic (CPV) system. This paper would review and survey the progress in the last 30 years including the optical design and development in the optics of solar concentrators for the CPV system. The detailed architectural design and optical principle of solar concentrators are presented to show various innovative and creative ideas of harnessing solar energy.
