Abstract
A compound parabolic concentrator (CPC) is a non-imaging device generally used in PV, thermal, or PV/thermal hybrid systems for the concentration of solar radiation on the target surface. This paper presents the geometric design, statistical modeling, parametric analysis, and geometric optimization of a two-dimensional low concentration symmetric compound parabolic concentrator for potential use in building-integrated and rooftop photovoltaic applications. The CPC was initially designed for a concentration ratio of “2×” and an acceptance half-angle of 30°. A MATLAB code was developed in house to provoke the CPC reflector’s profile. The height, aperture width, and concentration ratios were computed for different acceptance half-angles and receiver widths. The interdependence of optical concentration ratio and acceptance half-angle was demonstrated for a wide span of acceptance half-angles. The impact of the truncation ratio on the geometric parameters was investigated to identify the optimum truncation position. The profile of truncated CPC for different truncation positions was compared with full CPC. A detailed statistical analysis was performed to analyze the synergistic effects of independent design parameters on the responses using the response surface modeling approach. A set of optimized design parameters was obtained by establishing specified optimization criteria. A 50% truncated CPC with an acceptance half-angle of 21.58° and receiver width of 193.98 mm resulted in optimum geometric dimensions.
Highlights
The rapid growth in global electric energy demand exhorts the development of sustainable and renewable energy resources [1]
Another advantage of using a concentrated photovoltaic system is that the output electrical power increases by a factor equal to the concentration ratio of the given concentrator [33]
This section explores the influence of input design parameters on the geometry of the compound parabolic concentrator (CPC) collector
Summary
The rapid growth in global electric energy demand exhorts the development of sustainable and renewable energy resources [1]. Solar energy is the most promising resource among all the available options of renewable energy resources due to its abundance, cleanliness, and free availability [2]. Photovoltaic (PV) systems and solar thermal collectors are currently being used [3]. Solar PV systems have many distinct advantages, such as low maintenance costs due to the absence of any moving parts, quiet operation, no harmful greenhouse gas emissions into the atmosphere, and support for sustainable development. Solar PV technology plays a vital role in sustainable development by reducing the dependence on fast depleting fossil-fueled power plants [4]. The conversion efficiencies of conventional solar cells are inherently lower that further
