“…Ruelas et al 65 used Finite Element Analysis to analyze the structural integrity of STSC under wind loads. Their analysis showed that a 12.4 m 2 reflector, when subjected to wind load of 180 km/hour undergoes deformations of about 0.005 m and resulted in a maximum stress of 27 MPa.…”

The innovation in concentrated solar power (CSP) systems is one of the many vital solutions to meet the ever-increasing global energy demands. Among various CSP systems, point focus solar concentrators can attain a higher concentration ratio and helps reduce the size of the receiver, resulting in higher operating temperatures, lower thermal losses, and higher system exergy. This article presents a review on a particular class of CSP systems known as stationary point focus solar concentrators, that is, point focus solar concentrators having a stationary receiver. They can be categorized as (a) Scheffler reflector, (b) Scheffler-type concentrator, (c) high temperature concentrator, (d) central tower receiver, and (e) CNRS solar furnace. Having a stationary receiver helps reduce the maintenance and simplifies the plumbing network for heat transfer fluid. However, low maintenance might be a tradeoff on the performance side. This review systematically collates the literature on stationary point focus solar concentrators. Also, the basics of solar angles and various solar tracking systems applicable to this class of CSP systems are covered.

This work describes a new photovoltaic (PV) sun tracker design methodology that utilizes the advantages that the orientation and efficiency of the PV panel offer due to the latitude of the installation zone. Furthermore, the proposed design methodology is validated experimentally via the implementation of a solar tracker with dual axes at a specific location (27.5° latitude). In this case, the methodology enables the incorporation of a high-availability, low-accuracy, and low-cost tracking mechanism. Based on the results, the feasibility of this type of solar tracker for latitudes close to 30° is demonstrated, as this tracking system costs 27% less than the traditional commercial systems that use slew drives. This system increases the collection efficiency by 24% with respect to a fixed device. The proposed methodology, which is based on an orientation efficiency chart, can be applied to the construction or control of other types of solar tracker systems.

“…He also found that India and other countries use the Scheffler reflector‐type solar cookers in various consumable sectors which defeated the society's cultural perception. Ruelas et al 30 fabricated the model of Scheffler‐type solar concentrator which could be applied in heavy wind loads of up to 180 km/h. A 12.4 m 2 designed reflector area was subjected to 0.005 m deflection only and attained 27 MPa maximum stress.…”

This experimental analysis was performed with the aim to melt the ice into hot water at very high altitude regions such as Leh Ladakh. Three different designs of ice‐chamber were used to melt the ice with direct heating in minimum time. The radiations were focused on the receiver with the help of 1 m2 Scheffler solar concentrator exposed to the atmospheric situations of NIT Kurukshetra. The Scheffler solar concentrator was fabricated with fiber‐reinforced plastic material. The fabrication process is discussed in detail. The results obtained from the design showed that the ice frozen at −5°C completely melted, converting into water. The maximum temperature of water attained in the ice‐chamber with receiver 1 (circular plate with fins), 2 (CPC with fins), and 3 (copper crucible) was 57.7°C, 64.3°C, and 67.4°C, respectively.
